solar schools study

Hot off the presses, a new report released today by SEIA, The Solar Foundation, and Generation 180 shows vast growth in solar on K-12 schools in the United States. Solar capacity on our country’s schools has nearly doubled since the last version of this report in 2014, with 5,489 K-12 schools now powered by solar, totaling nearly 1,000 megawatts of electric generating capacity.

It’s no secret that many American schools are underfunded and classrooms often lack necessary resources for students to learn. Well, with the cost to install solar plummeting, schools are making the switch and seeing their electricity bills shrink, freeing up funds to use to strengthen what schools are here to do, which is teach our nation’s children.

The cost of a solar school installation pops off the page in this report, dropping 67% in the last decade and 19% last year alone. The result is a boom in installations allowing 4 million students in the United States to receive their education in a school powered by solar.

“There’s a reason solar is spreading so quickly across America’s school districts, and it’s pretty simple — when schools go solar, the entire community benefits,” said Abigail Ross Hopper, SEIA’s president and CEO.

These 5,000+ schools are running with much lower electricity bills, and those savings can go toward higher pay for our nation’s teachers, school supplies, textbooks and other essential resources. An investment in solar on a school is a direct investment in that community. Plus, what could be better than a science and conservation lesson right on the school grounds?

California schools lead the way in solar adoption with nearly 2,000 schools making the switch. But it’s notable that other states have picked up the pace including New Jersey, Arizona, Massachusetts, and New York. These states are setting an example and laying the groundwork for other states to follow.

When a school goes solar and cuts their energy costs, that puts investment back into what matters most: the students. Learn more about the report here and see if your community’s school has made the smart choice to invest in their community and go solar.

Wind and solar energy are the lowest cost options in most of the U.S., and that’ll make it very hard to stop the renewable energy freight train from running over fossil fuels.

Utilities that need to build new power generation facilities or replace old ones are going to have a hard time justifying anything but renewable energy in 2017 and beyond. Investment bank Lazard recently released its 11th analysis of the cost of new electricity generation, titled Lazard’s Levelized Cost Of Energy Analysis–Version 11.0, and showed that wind and solar energy are now cheaper than diesel, nuclear, coal, and in most cases natural gas.

Utilities and regulators are going to be hard-pressed to justify anything but renewable energy generation in the future. From Maine to Hawaii, the U.S.’s energy future is renewable.

How renewable energy costs stack up today

The table below shows Lazard’s analysis of the cost, on a per kWh basis, to build new power plants with different fuel sources and technologies. You can see that the lowest cost option is wind at 3 cents per kWh, followed by gas combined cycle that’s as cheap as 4.2 cents per kWh, and solar, which costs between 4.3 cents and 5.3 cents per kWh.

Energy source Low-End Estimate High-End Estimate
Crystalline Utility-Scale Solar PV 4.6 cents per kWh 5.3 cents per kWh
Thin-Film Utility-Scale Solar PV 4.3 cents per kWh 4.8 cents per kWh
Wind 3 cents per kWh 6 cents per kWh
Coal 6 cents per kWh 14.3 cents per kWh
Natural Gas Combined Cycle 4.2 cents per kWh 7.8 cents per kWh
Nuclear 12.2 cents per kWh 18.3 cents per kWh
Diesel 19.7 cents per kWh 28.1 cents per kWh
DATA SOURCE: LAZARD’S LEVELIZED COST OF ENERGY ANALYSIS–VERSION 11.0.

What you’ll also notice is that the range of costs is much wider for fossil fuels like natural gas. That’s because construction costs can be different depending on the state, fuel prices, and how often the plant is being used. Renewable energy, on the other hand, gets to cut to the front of the line on the grid, meaning nearly 100% of its electricity production is used, allowing for predictable electricity pricing.

What’s clear is that diesel, nuclear, and coal are all higher cost than both wind and solar energy on a per kWh basis. No matter how you slice it, renewable energy is winning versus fossil fuels on economics.

I’ll also point out that there’s no fuel cost risk for renewable energy. The wind and sun are zero-cost fuel sources, unlike extracted fuels, which could conceivably spike from current levels.

Trends are working against fossil fuels

It wasn’t long ago that Lazard’s analysis wasn’t so favorable to renewable energy. In 2010, version 4.0 of Lazard’s levelized cost of energy study had wind costs at 6.5-11.0 cents per kWh and solar at 13.4-19.4 cents per kWh. Natural gas, coal, and nuclear all beat solar on a cost basis, and in some cases beat wind.

Energy source Low-End Estimate High-End Estimate
Crystalline Utility-Scale Solar PV 13.4 cents per kWh 15.4 cents per kWh
Thin-Film Utility-Scale Solar PV 13.4 cents per kWh 18.8 cents per kWh
Wind 6.5 cents per kWh 11.0 cents per kWh
Coal 6.9 cents per kWh 15.2 cents per kWh
Natural Gas Combined Cycle 6.7 cents per kWh 9.6 cents per kWh
Nuclear 7.7 cents per kWh 11.4 cents per kWh

Clearly, the tides have shifted in the energy industry. Fossil fuels is at best flat and in some cases getting more expensive, while renewable energy costs are coming down every year. There’s no indication these trends will reverse course, and investors need to consider whether they’re using renewable energy’s growth as a tailwind for their portfolio or fighting the clear trends in energy. If these charts are any indication, fossil fuels’ days may be numbered.

Hurricanes Irma and Maria are still fresh in the mind of all of us who experienced them in the British Virgin Islands and wider Caribbean. These hurricanes have affected so many people, and everyone will have their own heart-breaking, moving and inspiring story to tell. I wanted to highlight a few, and share what I’ve been up to as well.


In the wake of the hurricanes, Virgin Unite has been working with Team Rubicon to bring practical, immediate and vital help to affected communities across the BVI. Lizzy Stileman, a member of Team Rubicon, shares her views about the impact of the hurricanes, and what needs to happen now. Meanwhile, John Ratliff – a long-time friend of Virgin Unite and member of our advisory council for the Virgin Unite Community – shares his story about flying out to the BVI to help on the ground. Below I’ve also shared Sam’s moving film, Help Hope Hurricanes, sharing his view from Virgin Gorda in the aftermath of Hurricane Irma.

Meanwhile, I have been continuing to rally aid and support for the BVI as we continue the recovery process. I recently met with more than 50 representatives of Caribbean governments and utility companies at the Caribbean Renewable Energy Forum in Miami. It was hosted by BMR Energy, one of Virgin Group’s investments, and gave us all a platform to discuss plans to expand the use of renewable energy in the region.

We highlighted the importance of renewable energy – solar, wind, geothermal and others – to reduce costs, reduce the harm being done to the environment and increase the resilience of their electric systems to withstand future hurricanes. In the aftermath of Irma and Maria, this message resonated more than ever.

It was inspiring to see so many decision makers and stakeholders gathered together, committed to tackling climate action now, and putting clean energy as the centerpiece of rebuilding efforts in the Caribbean. There has never been a more important time to push for this type of infrastructure.

Before returning to the BVI, I also travelled to Puerto Rico to meet with governor Ricardo Rosselló. I wanted to meet in person to share my heartfelt thanks for the incredible support Puerto Rico gave to the BVI during Hurricane Irma. We also discussed plans to power Puerto Rico with more clean energy, and the Rocky Mountain Institute plans to complete a study on the most effective ways to do this. It was a really positive visit, testament to the amazing people in Puerto Rico, in such a testing time.

Back in the BVI, I would echo Lizzy’s words: “There is still so much work to do here and there are so many people suffering. It will take years to recover, but it will recover.”

To help further support the affected communities please donate to the BVI Community Support Appeal and help us build a better, cleaner, stronger and more sustainable Caribbean region.

So … that was fast. US natural gas stakeholders barely had time to congratulate themselves for pushing coal out of the power generation market, and it looks like karma is already getting the last laugh. Low-cost renewable energy is beginning to nudge natural gas aside. In the most recent and striking development, California’s massive 262-megawatt Puente gas power plant proposal has been shelved, perhaps permanently.

Electricity Consumers Push Back On Natural Gas

Reporter Ivan Penn of the LA Times has the scoop on the Puente project, and he teases out several powerful forces at work against natural gas.

One key element is consumer pushback. At first glance, the proposal doesn’t seem overly controversial. The proposed plan, a project of NRG Energy, does not involve constructing a new facility. It would have replaced two existing gas units at the company’s existing Mandalay power generation facility in Oxnard, California.

All things being equal, the proposal would provide at least some degree of environmental benefit, because the new units would use 80% less water for cooling than the existing ones.

However, criticism of the new gas project was intense. Penn sums it up: earlier this month, a two-member review committee of the California Energy Commission took the rare step of issuing a statement recommending that the full Commission reject the plans after receiving “hundreds of messages protesting the project as another potential pollution threat to a community already overwhelmed by electricity-generating plants.”

The Rates Are Too Damn High

Aside from concerns about local air quality, Penn also cites an LA Times investigation indicating that the state’s energy policy has over-estimated the demand for natural gas power plants, resulting in artificially high rates:

“The commissioners’ recommendation followed Los Angeles Times investigations that showed the state has overbuilt the electricity system, primarily with natural gas plants, and has so much clean energy that it has to shut down some plants while paying other states to take the power California can’t use. The overbuilding has added billions of dollars to ratepayers’ bills in recent years.”

According to Penn, NRG officials maintain that older plant retirements by 2021 make replacement imperative to build up now.

At current costs, local ratepayers won’t get much relief if old power units are replaced with wind or solar.

My Beach, My Choice

Land use issues and environmental justice issues also come into play. NRG’s Mandalay power generation facility is located on the beach, and as NRG acknowledges, in 2014 the City of Oxnard enacted a moratorium on coastal development.

That complicates development plans within the power plant site, though NRG emphasizes that the final decision rests with state-level regulators.

Among those objecting to the plant from outside the local community is billionaire investor Tom Steyer, who co-authored an op-ed about the proposed facility raising the environmental justice issue:

“…in our state, not all beaches are created equal. That becomes painfully clear if you drive 50 miles north of Los Angeles to Oxnard, where the beaches have been seized by corporate polluters, marred by industrial waste and devastated by three fossil-fuel power plants that sit along the shoreline.

“Oxnard has more coastal power plants than any other city in the state, and not coincidentally, its population is predominantly Latino and low-income….”

Oxnard residents — and no doubt, real estate developers — are looking forward to transitioning coastal property out of industrial use altogether. Here’s LA Times reporter Dan Weikel on that topic:

“Many residents of this predominantly Latino city with a population of 205,000 say they are fed up with the degradation. Their growing dissatisfaction with the condition of large sections of beach has coalesced into an effort to deindustrialize and restore the shoreline of this city that is framed by Ventura and Camarillo and wraps around the town of Port Hueneme.”

So, What’s The Solution?

The Puente project has been suspended, not canceled. However, chances of revival are slim. Although the most recent study affirms that renewable energy is a more expensive choice currently, Steyer points out that the redevelopment of Oxnard’s beachfront could be balanced out by new economic activity related to tourism and recreation.

That opens up a whole ‘nother can of worms, as waterfront development typically drives up the cost of housing, squeezing former residents to outer rims with longer commutes and fewer resources.

Sticking to the energy cost issue, the basic problem comes down to local energy vs. long distance transmission.

NRG makes the case that local energy generation is more reliable. That’s a fair assessment as a general principle, as the old model of centralized power plants falls out of favor. Local and on-site generation is becoming a consensus argument among energy experts, regardless of the power source.

On the other hand, the risk involved in transmitting electricity from remote wind farms and solar power plants could be offset by local storage sites, where the growing microgrid movement would come into play.

New tools for financing energy efficiency improvements could also help tamp down local energy demand and ease the way for a more interactive grid that enables consumers to tweak their electricity consumption to help prevent outages.

Cities like Oxnard can also tap into a growing renewable energy knowledge base that leverages local opportunities for renewable energy development and energy efficiency improvements.

Most of all, the Trump administration’s willy-nilly approach to oil and gas development — for example, a new proposal involving drilling along the Pacific coast — raises the stakes for citizens far outside of the communities dealing with local land use issues, leading to a groundswell of support for alternatives.

Clean Technica

Outgoing JPS President Kelly Tomblin.

Power utility Jamaica Public Service Company (JPS) plans to build a 24.5-megawatt facility to store energy as a safeguard against power outages.

It’s described as the first of its kind in the Caribbean.

JPS plans to build the facility next year, but no cost was disclosed up to press time. It will act like a giant battery that charges when solar- or wind-energy plants generate energy. It then kicks into action, the less power these renewable plants generate due to cloud cover or low wind speeds.

“The proposed initiative will allow JPS to provide a high-speed response when the output from renewables is suddenly reduced to mitigate stability and power quality issues that cause outages to customers,” stated JPS in a release.

The company did not respond immediately to questions seeking more details. It initially said the release, which appeared on the Jamaica Stock Exchange’s website, was not meant to be made public until Monday.

Peak energy usage in Jamaica starts at 6.30 p.m. to 9.30 p.m, which represents a leisure peak, rather than an economic development peak. That becomes important as solar plants reduce power generation just as the peak period starts.

PROVIDING VALUE

Additionally, wind farms optimally generate power at nights but after peak periods. The storage facility would, therefore, provide value as it comes into effect at peak periods utilising the power already stored.

The facility requires regulatory approval from the Office of Utilities Regulation (OUR) but in anticipation, the JPS board of directors last week signed off on the hybrid energy storage solution, the release stated. The project involves construction of a 24.5MW facility at the Hunts Bay Power Plant Substation, and will be a combination of high-speed and low-speed flywheels and containerised lithium-ion batteries. Once approved for construction, it would become operational by the third quarter of 2018.

“The innovation will help to secure grid stability and reliability in the face of increasing intermittent renewable energy. The energy storage solution will have power readily available in the event that solar and wind renewable systems, suddenly lose power due to cloud cover, reduced wind or other interruptions,” stated the release.

It will also provide a much faster, cost effective and environmentally friendly spinning reserve or backup as an alternative to traditional generation spinning reserve which is required by the company.

INCREASED FLEXIBILITY

Additionally, the JPS is seeking to convert more generating units to use liquefied natural gas (LNG). This will result in increased flexibility of the generating units, as the JPS moves to ensure that customers have a more reliable, affordable and sustainable quality service. JPS continues to steadily diversify from solely heavy oil fuel to include natural gas and some 115MW of renewables.

Energy efficiency is now an integral part of JPS’ push to become a more modern and cleaner energy provider.

Jamaica has an energy intensity of approximately 4,800 kilowatt-hours (kWh) per US$1,000 of gross domestic product. To put that into perspective, last December outgoing JPS president Kelly Tomblin described it as one of the highest in Latin America and the Caribbean. She indicated that such inefficient use of energy constrains Jamaica’s growth.

The country, however, has made some gains in its efficiency drive. It ranked 92nd in the World Economic Forum’s Global Energy Architecture Performance Index Report 2017, up from 98 the year before.

The rise in rank was attributed to the 80MW of renewables added in 2016 and plans for an additional 100MW of renewable this year.

In Jamaica last year, Wigton Wind Farm III added 24MW of renewable capacity, BMR Windfarm added 36.3MW, and WRB Content Solar, 20MW. The country saved around US$18 million (J$2.3 billion) in oil imports based on the 80MW renewable energy projects.

Concurrently, those renewable projects saved 800,000 metric tonnes in toxic carbon emissions, according to the energy ministry.

Bloomberg New Energy Finance’s outlook shows renewables will be cheaper almost everywhere in just a few years.

Solar power, once so costly it only made economic sense in spaceships, is becoming cheap enough that it will push coal and even natural-gas plants out of business faster than previously forecast.

That’s the conclusion of a Bloomberg New Energy Finance outlook for how fuel and electricity markets will evolve by 2040. The research group estimated solar already rivals the cost of new coal power plants in Germany and the U.S. and by 2021 will do so in quick-growing markets such as China and India.

The scenario suggests green energy is taking root more quickly than most experts anticipate. It would mean that global carbon dioxide pollution from fossil fuels may decline after 2026, a contrast with the International Energy Agency’s central forecast, which sees emissions rising steadily for decades to come.

“Costs of new energy technologies are falling in a way that it’s more a matter of when than if,” said Seb Henbest, a researcher at BNEF in London and lead author of the report.

The report also found that through 2040:

  • China and India represent the biggest markets for new power generation, drawing $4 trillion, or about 39 percent all investment in the industry.
  • The cost of offshore wind farms, until recently the most expensive mainstream renewable technology, will slide 71 percent, making turbines based at sea another competitive form of generation.
  • At least $239 billion will be invested in lithium-ion batteries, making energy storage devices a practical way to keep homes and power grids supplied efficiently and spreading the use of electric cars.
  • Natural gas will reap $804 billion, bringing 16 percent more generation capacity and making the fuel central to balancing a grid that’s increasingly dependent on power flowing from intermittent sources, like wind and solar.

BNEF’s conclusions about renewables and their impact on fossil fuels are most dramatic. Electricity from photovoltaic panels costs almost a quarter of what it did in 2009 and is likely to fall another 66 percent by 2040. Onshore wind, which has dropped 30 percent in price in the past eight years, will fall another 47 percent by the end of BNEF’s forecast horizon.

That means even in places like China and India, which are rapidly installing coal plants, solar will start providing cheaper electricity as soon as the early 2020s.

“These tipping points are all happening earlier and we just can’t deny that this technology is getting cheaper than we previously thought,” said Henbest.

Coal will be the biggest victim, with 369 gigawatts of projects standing to be cancelled, according to BNEF. That’s about the entire generation capacity of Germany and Brazil combined.

Capacity of coal will plunge even in the U.S., where President Donald Trump is seeking to stimulate fossil fuels. BNEF expects the nation’s coal-power capacity in 2040 will be about half of what it is now after older plants come offline and are replaced by cheaper and less-polluting sources such as gas and renewables.

In Europe, capacity will fall by 87 percent as environmental laws boost the cost of burning fossil fuels. BNEF expects the world’s hunger for coal to abate starting around 2026 as governments work to reduce emissions in step with promises under the Paris Agreement on climate change.

“Beyond the term of a president, Donald Trump can’t change the structure of the global energy sector single-handedly,” said Henbest.

All told, the growth of zero-emission energy technologies means the industry will tackle pollution faster than generally accepted. While that will slow the pace of global warming, another $5.3 trillion of investment would be needed to bring enough generation capacity to keep temperature increases by the end of the century to a manageable 2 degrees Celsius (3.6 degrees Fahrenheit), the report said.

The data suggest wind and solar are quickly becoming major sources of electricity, brushing aside perceptions that they’re too expensive to rival traditional fuels.

By 2040, wind and solar will make up almost half of the world’s installed generation capacity, up from just 12 percent now, and account for 34 percent of all the power generated, compared with 5 percent at the moment, BNEF concluded.

Thousands of photovoltaic panels across the UK generate 8.7GW, smashing previous high of 8.48GW earlier this month

Woman relaxes on deckchair in London.

Solar power has broken new records in the UK by providing nearly a quarter of the country’s electricity needs, thanks to sunny skies and relatively low summer demand.

National Grid said the thousands of photovoltaic panels on rooftops and in fields across the UK were generating 8.7GW, or 24.3% of demand at 1pm on Friday, smashing the previous high of 8.48GW earlier this month.

Experts said the unprecedented share for solar energy meant about 60% of the UK’s power was low carbon, taking into account Britain’s wind farms and nuclear power stations too. That figure is normally around 50%.

National Grid, which is tasked with ensuring a match between supply and demand for electricity, said it was excited but unfazed by the challenge of accommodating “significant volumes” of renewables.

Solar provided a record percentage of UK power at 1pm on 26 May 2017
 Screen Shot 2017-05-29 at 20.40.20

Duncan Burt, who manages day-to-day operation of the grid, said: “We have planned for these changes to the energy landscape and have the tools available to ensure we can balance supply and demand.”

Hannah Martin, head of energy at Greenpeace, said: “Today’s new record is a reminder of what the UK could achieve if our government reversed its cuts to support for solar, and backed the clean technologies that could provide jobs, business opportunities and plentiful clean energy for decades to come.”

The milestone reached on Friday is the latest in a series of records for solar, which has grown from almost nothing seven years ago to 12GW of capacity today. Last summer it provided more power than the UK’s last 10 coal-fired power stations.

In April this year, Britain achieved its first-ever full working day without coal powersince it started burning the fuel in 1882, thanks in part to solar energy.

Solar’s rapid growth is overturning conventions for the managers of the UK’s power grid. In March, for the first time ever, the amount of electricity demanded by homes and businesses in the afternoon was lower than it was in the night, thanks to the cut in demand due to solar panels.

Alastair Buckley, a solar expert at the University of Sheffield, said of the latest record: “I think it’s a positive sign. It’s free electricity today, for the consumer, and we should make the most of it.”

He said that with solar continuing to be installed despite the government’s drastic subsidy cuts in 2016, further records will certainly be broken this summer and for years to come.

Buckley said the grid could handle a far greater proportion of solar power than currently seen, because gas power stations could be ramped down. For National Grid, periods of high pressure bringing lovely weather to the UK like this week were: “really predictable, so easy to plan for,” Buckley said.

Robert Gross of Imperial College said: “This doesn’t pose fundamental problem for the grid – many sunnier countries manage a similar proportion of solar on a much more regular basis.”

Government statistics published on Thursday show that UK solar power capacity has grown from 11.3GW in April last year to 12.1GW this year, enough to power 3.8m homes.

As the debate intensifies over the possible rate increases which could face Jamaicans as more and more customers leave the Jamaica Public Service Company’s (JPS) grid, there are calls for a collaborative approach to the issue.

Manager of the Grid Performance Department at the JPS, Lincoy Small, says the various stakeholders must engage in dialogue to find an approach to provide the cheapest source of electricity to Jamaicans.

According to Small, it cannot be a matter of either renewable energy (RE) or staying on the JPS grid but a combination of the two.

“JPS is not telling people that renewable is not the way to go, because JPS even operates renewable facilities, but the key thing is to get them (grid and RE) working together in tandem to come up with the best synergy of what is best for the customer and what is best for the country,” said Small.

His comments came as Robert Wright, president of the Jamaica Solar Energy Association, told The Sunday Gleaner he has no desire for Jamaicans to leave the JPS grid.

Grid Stability

Wright said he strongly believes RE should be maximised and not just limited to large systems scattered across the island, but smaller systems distributed right across the country.

“When you have these smaller systems spread across the country it provides for better grid stability, and also it allows for more people to participate in clean energy as opposed to simply relying on large solar farms,” said Wright.

But Small said, based on experience due to the unpredictability of RE, the JPS sometimes has to resort to load shedding when customers jump on and off the grid.

He reiterated that JPS’s customers could face additional cost if the impact of RE on the grid is not handled carefully.

“So we are accepting solar power from the customers and as soon as something happens it drops off, and does so much quicker than the grid can even respond on some of those occasions, and as a result you have to be running expensive machines that are quicker to deal with those sun drop-offs or have to shed people’s light,” argued Small.

“And if you run these expensive machines or shed people’s light it means the overall cost to run the grid is going to be absorbed by the customer; you are going to have to pay for a more expensive energy source.”

The JPS executive said the company is actively seeking to incorporate new technology to deal with the loss of the intermittent renewable resources.

But Wright argued that the good news for Jamaicans is that the cost of RE is declining rapidly, enabling it to compete with traditional sources of energy.

“A system that a typical household would need in Jamaica two years ago would cost $1 million; that same system today cost $500,000, so we have seen a significant drop in prices,” said Wright.

“Also what is revolutionary is that the cost of batteries has gone down a lot, so now, even more than before, we will be able to offer that to residential customers at an affordable price.

“What is becoming more available now are systems called micro-inverters, and these allow you to install a very simple rooftop system which is cheaper, faster to install and is more appropriate for affordable housing developments, and so on.”

Batteries Expensive

But Small countered that with solar and wind on average only available for 20 and 35 per cent of the day, respectively, and the cost of buying and replacing batteries being expensive, it might be cheaper for customers to get their power from the JPS grid when RE is not available.

“It (solar) is a good thing to have, but it cannot be operated in isolation, and that is something a lot of people in the solar business not telling their customers,” said Small.

“Because even if you get a panel or a wind turbine and you get the battery, you are going to need a grid to at least charge up that battery for the 80 per cent of the time you are without solar or the 65 per cent of the time you are without wind.

“Plus, you will have to be replacing the battery every two to three years for full value, and batteries cost much more than solar panels.”

Small said the JPS is focused on supplying power as cheaply as possible so persons can take the cheap power from the grid rather than go buy a battery and use the solar power and the wind when it is available.

With Jamaica being a signatory to the Paris Climate Change Agreement, the utilisation of more RE forms part of the National Energy Policy which sees the country aiming to have 30 per cent RE penetration by 2030.

The country is currently at approximately 10 per cent of the quota, with roughly 300 net billing customers (those who have solar systems which allows them to consume energy and sell surplus) and around 10 larger customers.

President of the Jamaica Public Service Company, JPS, Kelly Tomblin, is rejecting claims that she’s using scare tactics to keep businesses from turning to renewable sources of energy.

In an interview yesterday on Nationwide This Morning, Chief Executive Officer of Solar Buzz Jamaica, Jason Robinson, accused JPS of using ‘scare tactics’.

This was in response to comments attributed to Ms. Tomblin in a recent Gleaner report that the company could be forced to raise electricity rates if its top customers leave the grid.

But speaking with Nationwide News yesterday, Ms. Tomblin sought to clarify the comments she made to the Gleaner newspaper.

She’s insisting she’s not using a scare tactics.

Ms. Tomblin says she would prefer companies stay on the power grid.

This, as the intermittent use of the grid is more of a burden on JPS than if a company were to be removed completely.

And, Ms. Tomblin says the JPS doesn’t build LNG plants contrary to Mr Robinson’s claim.

He’d said the light and power company has been offering to set up small LNG plants for large companies, which would also take them off the grid.

She’s also refuting his claim that JPS’s rates are going up.

With many local entities turning to solar systems or other renewable systems to reduce their reliance on more expensive energy supplied by the Jamaica Public Service Company (JPS), there is a another indication that persons who remain on the JPS grid could face the consequences.

“We all should be concerned and thoughtful. You don’t want everybody who can afford solar on their roof going off the grid because you would still have to pay for the grid,” CEO of the JPS, Kelly Tomblin, told The Sunday Gleaner during a recent interview.

“How do we take care of a particular company so that we also take care of the whole? How do we find a way to make it affordable for everybody and don’t just let people cherry-pick off the grid?” added Tomblin.

There is no official registry of the amount of renewable energy being utilised on the island, but it is estimated that approximately 35 megawatts of renewable energy has been installed between residential and business customers in recent years.

The target is to have 20 per cent of the country’s energy need being supplied by renewable sources by 2018, moving to 30 per cent by 2030.

Energy Sales

The JPS has recorded four years of decline in energy sales from 2010 to 2014, but has seen a turnaround in the last two years with a two per cent increase in 2015 and a four per cent increase in 2016.

“This could be due to the fact that the cost of electricity to customers has dropped by about 25 per cent over that time (usage tends to increase when the price of electricity is lower),” the JPS said in an emailed response to questions from our news team.

According to the JPS, while it has not yet seen any revenue fallout from renewable energy installations, it recognises “that energy sales could have been higher if some customers had not gone off the grid”.

If more paying customers move to renewables and leave the JPS, the company will be selling to a smaller group of paying customers and could be forced to find alternative ways to remain profitable, which could see electricity cost increase for some customers.

If Top Customers Left

Tomblin admitted that if the company’s top 50 customers were all to leave the grid it would cause a serious problem, but she argued that she is confident that these companies are cognisant of their responsibility to the Jamaican people.

“I am really encouraged, having been in meetings with our top 50 customers, and we are having a lot of meetings with the Private Sector Organisation of Jamaica (PSOJ) and the Energy Committee to say how we can balance personal and country interest,” said Tomblin.

“People who are adding solar are doing so during the day; that is not when Jamaica has a peak. So unless they have storage we have to maintain the same power plant and the same grid, because they come on the JPS system at nights, so they still have to pay and, therefore, it is not that much of an impact to the system,” said Tomblin.

But PSOJ President Paul Scott said the decision to remain on the grid or not is one entities will have to decide based on what is best for their business.

“I am aware of some members who have not come off the grid because of the impact it might have on residential users, while other members have come off the grid,” said Scott, who is a member of the Electricity Sector Enterprise Team.

“So one must make their own economic decision based upon their own situation. Serious companies would take that (impact on residential users) into consideration. I would encourage our members to make decisions that will impact the overall competitiveness of Jamaica. Different industries have different utility requirements and therefore, you can’t generalise.”

According to Scott, the use of the grid will change over time, as PSOJ members, and the private sector as a whole, are always going to calculate the cost of energy as a significant part of their business.
