The Grand Canyon Trust and other environmental groups are pressing for tighter pollution controls on the coal-burning power plant near Page.

They say air pollution from the plant is marring views at Grand Canyon National Park even after the power station underwent improvements in the 1990s. But the owners of the plant contend it is one of the cleanest in the West and that further reductions in pollutants are scheduled.

The National Parks Conservation Association, Sierra Club, Grand Canyon Trust, San Juan Citizens Alliance, To Nizhoni Ani and Dine CARE filed a petition with the Interior Department on Tuesday seeking to have Interior and the Environmental Protection Agency require state-of-the-art pollution devices on the Navajo Generating Station.

The 2,250-megawatt plant is one of the larger coal-fired plants in the country and employs 545.

A similar petition filed a decade ago by conservation groups resulted in the EPA requiring new controls at the Mohave Generating Station in Laughlin, Nev.

The owners of that plant said the improvements were cost-prohibitive and the facility has been shut down.

In essence, the groups are pressing the National Park Service to state that air in the Grand Canyon is not as clean as the Clean Air Act requires in a national park, and that the power plant near Page is one reason why.

The Park Service is already on board, following years of air quality modeling.

"There's ample data that shows that Navajo Generating Station contributes to visibility impairment at the park," said Chris Shaver, chief of the Park Service division that monitors air quality in the nation's parks.

Researchers at the Grand Canyon say smog emitted in Southern California, Las Vegas, and Phoenix also likely contributes to poor visibility in the Grand Canyon.

The ultimate goal is to have the plant convert partly to being run from renewable energy, or to close, said Roger Clark, of the Grand Canyon Trust.

"It's had a good run. It's time to go to pasture," Clark said of Navajo Generating Station, scheduled to operate to 2026.

The power plant discharges 34,000 tons of nitrogen oxides, 1,900 tons of particulate matter and 3,690 tons of sulfur dioxide and 20 million tons of carbon dioxide into the air annually, the groups say in their petition.

They are pressing for expensive, top-notch pollution controls.

But those would not reduce greenhouse gases, like carbon dioxide.

The U.S. Bureau of Reclamation, Salt River Project, Los Angeles Department of Water and Power, Arizona Public Service, Nevada Power, and Tucson Electric Power own the Navajo Generating Station, which generates enough electricity to supply more than 500,000 homes in Arizona, Nevada and California and pump Colorado River water to Phoenix via the Central Arizona Project.

Operating costs for the plant, located on the Navajo Nation, run $200 million annually, not including coal purchased from the Kayenta Mine and Peabody Coal to feed it.

The plant is also supplied with a little less than 27,000 acre-feet of water per year from Lake Powell — or more than twice as much water as the city of Flagstaff consumes annually.

The owners of Navajo Generating Station spent more than $400 million in the 1990s to greatly cut some of the farthest-traveling air pollution from the plant, under pressure from the Grand Canyon Trust and the EPA.

SRP calls the plant, operating since 1974, among the cleanest coal-fired power stations in the West.

"The emissions at Navajo Generating Station are at rates that are comparable to what have been set for new plants," said Kevin Wanttaja, manager of environmental services at Salt River Project, which operates the Navajo Generating Station.

The utility plans to add more equipment to remove nitrogen oxides, Wanttaja said, but the groups filing the petition say that doesn't go far enough.

"Maybe it will need to shut down if it can't be cleaned up, but we think a transition from coal to renewables in the next 10 years is going to have to happen one way or another," said Andy Bessler, of the Sierra Club office in Flagstaff.

Gaza’s sole electricity plant shuts down after running out of fuel

Gaza Power Plant Shutdown underscores the Gaza Strip's fuel ban, Israeli blockade, and electricity crisis, cutting megawatts, disrupting hospitals and quarantine centers, and exposing fragile energy supply, GEDCO warnings, and public health risks.

 

Key Points

An abrupt halt of Gaza's sole power plant due to a fuel ban, deepening the electricity crisis and straining hospitals.

✅ Israeli fuel ban halts Gaza's only power plant

✅ Available supply drops far below 500 MW demand

✅ Hospitals and COVID-19 quarantine centers at risk

 

The only electricity plant in the Gaza Strip shut down yesterday after running out of fuel banned from entering the besieged enclave by the Israeli occupation, Gaza Electricity Distribution Company announced.

“The power plant has shut down completely,” the company said in a brief statement, as disruptions like China power cuts reveal broader grid vulnerabilities.

Israel banned fuel imports into Gaza as part of punitive measures over the launching incendiary balloons from the Strip.

On Sunday, GEDCO warned that the industrial fuel for the electricity plant would run out, mirroring Lebanon's fuel shortage challenges, on Tuesday morning.

Since 2007, the Gaza Strip suffered under a crippling Israeli blockade that has deprived its roughly two million inhabitants of many vital commodities, including food, fuel and medicine, and regional strains such as Iraq's summer electricity needs highlight broader power insecurity.

As a result, the coastal enclave has been reeling from an electricity crisis, similar to when the National Grid warned of short supply in other contexts.

The Gaza Strip needs some 500 megawatts of electricity – of which only 180 megawatts are currently available – to meet the needs of its population, while Iran supplies about 40% of Iraq's electricity in the region.

Spokesman of the Ministry of Health in Gaza, Ashraf Al Qidra, said the lack of electricity undermines offering health services across Gaza’s hospitals.

He also warned that the lack of electricity would affect the quarantine centres used for coronavirus patients, reinforcing the need to keep electricity options open during the pandemic.

Gaza currently has three sources of electricity: Israel, which provides 120 megawatts and is advancing coal use reduction measures; Egypt, which supplies 32 megawatts; and the Strip’s sole power plant, which generates between 40 and 60 megawatts.

Why California's Climate Policies Are Causing Electricity Blackouts

California Rolling Blackouts expose grid reliability risks amid a heatwave, as CAISO curtails power while solar output fades at sunset, wind stalls, and scarce natural gas and nuclear capacity plus PG&E issues strain imports.

 

Key Points

Grid outages during heatwaves from low reserves, fading solar, weak wind, and limited firm capacity.

✅ Heatwave demand rose as solar output dropped at sunset

✅ Limited imports and gas, nuclear shortfalls cut reserves

✅ Policy, pricing, and maintenance gaps increased outage risk

 

Millions of Californians were denied electrical power and thus air conditioning during a heatwave, raising the risk of heatstroke and death, particularly among the elderly and sick. 

The blackouts come at a time when people, particularly the elderly, are forced to remain indoors due to Covid-19, and as later heat waves would test the grid again statewide.

At first, the state’s electrical grid operator last night asked customers to voluntarily reduce electricity use. But after lapses in power supply pushed reserves to dangerous levels it declared a “Stage 3 emergency” cutting off power to people across the state at 6:30 pm.

The immediate reason for the black-outs was the failure of a 500-megawatt power plant and an out-of-service 750-megawatt unit not being available. “There is nothing nefarious going on here,” said a spokeswoman for California Independent System Operator (CAISO). “We are just trying to run the grid.”

But the underlying reasons that California is experiencing rolling black-outs for the second time in less than a year stem from the state’s climate policies, which California policymakers have justified as necessary to prevent deaths from heatwaves, and which it is increasingly exporting to Western states as a model.

In October, Pacific Gas and Electric cut off power to homes across California to avoid starting forest fires after reports that its power lines may have started fires in recent seasons. The utility and California’s leaders had over the previous decade diverted billions meant for grid maintenance to renewables. 

And yesterday, California had to impose rolling blackouts because it had failed to maintain sufficient reliable power from natural gas and nuclear plants, or pay in advance for enough guaranteed electricity imports from other states.

It may be that California’s utilities and their regulator, the California Public Utilities Commission, which is also controlled by Gov. Newsom, didn’t want to spend the extra money to guarantee the additional electricity out of fears of raising California’s electricity prices even more than they had already raised them.

California saw its electricity prices rise six times more than the rest of the United States from 2011 to 2019, helping explain why electricity prices are soaring across the state, due to its huge expansion of renewables. Republicans in the U.S. Congress point to that massive increase to challenge justifications by Democrats to spend $2 trillion on renewables in the name of climate change.

Even though the cost of solar panels declined dramatically between 2011 and 2019, their unreliable and weather-dependent nature meant that they imposed large new costs in the form of storage and transmission to keep electricity as reliable. California’s solar panels and farms were all turning off as the blackouts began, with no help available from the states to the East already in nightfall.

Electricity from solar goes away at the very moment when the demand for electricity rises. “The peak demand was steady in late hours,” said the spokesperson for CAISO, which is controlled by Gov. Gavin Newsom, “and we had thousands of megawatts of solar reducing their output as the sunset.”

The two blackouts in less than a year are strong evidence that the tens of billions that Californians have spent on renewables come with high human, economic, and environmental costs.

Last December, a report by done for PG&E concluded that the utility’s customers could see blackouts double over the next 15 years and quadruple over the next 30.

California’s anti-nuclear policies also contributed to the blackouts. In 2013, Gov. Jerry Brown forced a nuclear power plant, San Onofre, in southern California to close.

Had San Onofre still been operating, there almost certainly would not have been blackouts on Friday as the reserve margin would have been significantly larger. The capacity of San Onofre was double that of the lost generation capacity that triggered the blackout.

California's current and former large nuclear plants are located on the coast, which allows for their electricity to travel shorter distances, and through less-constrained transmission lines than the state’s industrial solar farms, to get to the coastal cities where electricity is in highest demand.

There has been very little electricity from wind during the summer heatwave in California and the broader western U.S., further driving up demand. In fact, the same weather pattern, a stable high-pressure bubble, is the cause of heatwaves, since it brought very low wind for days on end along with very high temperatures.

Things won’t be any better, and may be worse, in the winter, with a looming shortage as it produces far less solar electricity than the summer. Solar plus storage, an expensive attempt to fix problems like what led to this blackout, cannot help through long winters of low output.

California’s electricity prices will continue to rise if it continues to add more renewables to its grid, and goes forward with plans to shut down its last nuclear plant, Diablo Canyon, in 2025.

Had California spent an estimated $100 billion on nuclear instead of on wind and solar, it would have had enough energy to replace all fossil fuels in its in-state electricity mix.

To manage the increasingly unreliable grid, California will either need to keep its nuclear plant operating, build more natural gas plants, underscoring its reliance on fossil fuels for reliability, or pay ever more money annually to reserve emergency electricity supplies from its neighbors.

After the blackouts last October, Gov. Newsom attacked PG&E Corp. for “greed and mismanagement” and named a top aide, Ana Matosantos, to be his “energy czar.” 

“This is not the new normal, and this does not take 10 years to solve,” Newsom said. “The entire system needs to be reimagined.”

Climate Solution: Use Carbon Dioxide to Generate Electricity

Methane Hydrate CO2 Sequestration uses carbon capture and nitrogen injection to swap gases in seafloor hydrates along the Gulf of Mexico, releasing methane for electricity while storing CO2, according to new simulation research.

 

Key Points

A method injecting CO2 and nitrogen into hydrates to store CO2 while releasing methane for power.

✅ Nitrogen aids CO2-methane swap in hydrate cages, speeding sequestration

✅ Gulf Coast proximity to emitters lowers transport and power costs

✅ Revenue from methane electricity could offset carbon capture

 

The world is quickly realizing it may need to actively pull carbon dioxide out of the atmosphere to stave off the ill effects of climate change. Scientists and engineers have proposed various carbon capture techniques, but most would be extremely expensive—without generating any revenue. No one wants to foot the bill.

One method explored in the past decade might now be a step closer to becoming practical, as a result of a new computer simulation study. The process would involve pumping airborne CO2 down into methane hydrates—large deposits of icy water and methane right under the seafloor, beneath water 500 to 1,000 feet deep—where the gas would be permanently stored, or sequestered. The incoming CO2 would push out the methane, which would be piped to the surface and burned to generate electricity, whether sold locally or via exporters like Hydro-Que9bec to help defray costs, to power the sequestration operation or to bring in revenue to pay for it.

Many methane hydrate deposits exist along the Gulf of Mexico shore and other coastlines. Large power plants and industrial facilities that emit CO2 also line the Gulf Coast, where EPA power plant rules could shape deployment, so one option would be to capture the gas directly from nearby smokestacks, keeping it out of the atmosphere to begin with. And the plants and industries themselves could provide a ready market for the electricity generated.

A methane hydrate is a deposit of frozen, latticelike water molecules. The loose network has many empty, molecular-size pores, or “cages,” that can trap methane molecules rising through cracks in the rock below. The computer simulation shows that pushing out the methane with CO2 is greatly enhanced if a high concentration of nitrogen is also injected, and that the gas swap is a two-step process. (Nitrogen is readily available anywhere, because it makes up 78 percent of the earth’s atmosphere.) In one step the nitrogen enters the cages; this destabilizes the trapped methane, which escapes the cages. In a separate step, the nitrogen helps CO2 crystallize in the emptied cages. The disturbed system “tries to reach a new equilibrium; the balance goes to more CO2 and less methane,” says Kris Darnell, who led the study, published June 27 in the journal Water Resources Research. Darnell recently joined the petroleum engineering software company Novi Labs as a data scientist, after receiving his Ph.D. in geoscience from the University of Texas, where the study was done.

A group of labs, universities and companies had tested the technique in a limited feasibility trial in 2012 on Alaska’s North Slope, where methane hydrates form in sandstone under deep permafrost. They sent CO2 and nitrogen down a pipe into the hydrate. Some CO2 ended up being stored, and some methane was released up the same pipe. That is as far as the experiment was intended to go. “It’s good that Kris [Darnell] could make headway” from that experience, says Ray Boswell at the U.S. Department of Energy’s National Energy Technology Laboratory, who was one of the Alaska experiment leaders but was not involved in the new study. The new simulation also showed that the swap of CO2 for methane is likely to be much more extensive—and to happen quicker—if CO2 enters at one end of a hydrate deposit and methane is collected at a distant end.

The technique is somewhat similar in concept to one investigated in the early 2010s by Steven Bryant and others at the University of Texas. In addition to numerous methane hydrate deposits, the Gulf Coast has large pools of hot, salty brine in sedimentary rock under the coastline. In this system, pumps would send CO2 down into one end of a deposit, which would force brine into a pipe that is placed at the other end and leads back to the surface. There the hot brine would flow through a heat exchanger, where heat could be extracted and used for industrial processes or to generate electricity, supporting projects such as electrified LNG in some markets. The upwelling brine also contains some methane that could be siphoned off and burned. The CO2 dissolves into the underground brine, becomes dense and sinks further belowground, where it theoretically remains.

Either system faces big practical challenges, and building shared CO2 storage hubs to aggregate captured gas is still evolving. One is creating a concentrated flow of CO2; the gas makes up only .04 percent of air, and roughly 10 percent of the smokestack emission from a typical power plant or industrial facility. If an efficient methane hydrate or brine system requires an input that is 90 percent CO2, for example, concentrating the gas will require an enormous amount of energy—making the process very expensive. “But if you only need a 50 percent concentration, that could be more attractive,” says Bryant, who is now a professor of chemical and petroleum engineering at the University of Calgary. “You have to reduce the [CO2] capture cost.”

Another major challenge for the methane hydrate approach is how to collect the freed methane, which could simply seep out of the deposit through numerous cracks and in all directions. “What kind of well [and pipe] structure would you use to grab it?” Bryant asks.

Given these realities, there is little economic incentive today to use methane hydrates for sequestering CO2. But as concentrations rise in the atmosphere and the planet warms further, and as calls for an electric planet intensify, systems that could capture the gas and also provide energy or revenue to run the process might become more viable than techniques that simply pull CO2 from the air and lock it away, offering nothing in return.

Trudeau vows to regulate oil and gas emissions, electric car sales

Canada Oil and Gas Emissions Cap sets five-year targets to cut sector emissions toward net-zero by 2050, alongside an EV mandate, carbon pricing signals, and support for carbon capture, clean energy jobs, climate policy.

 

Key Points

A federal policy to regulate and reduce oil and gas emissions via 5-year targets, reaching net-zero by 2050.

✅ Regulated 5-year milestones to cut oil and gas emissions to net-zero by 2050

✅ Interim EV mandate: 50% by 2030; 100% zero-emission sales by 2035

✅ $2B fund for clean energy jobs in oil- and gas-reliant communities

 

Liberal Leader Justin Trudeau vowed to regulate total emissions from Canada’s oil and gas producers as he laid out his first major climate change promises of the campaign Sunday, a plan that was welcomed by several environmental and climate organizations.

Trudeau said that if re-elected, the Liberals will set out regulated five-year targets for emissions from oil and gas production to get them to net-zero emissions by 2050, a goal that, according to an IEA report will require more electricity, but also create a $2 billion fund to create jobs in oil and gas-reliant communities in Alberta, Saskatchewan and Newfoundland and Labrador.

“Let’s be realistic, over a quarter of Canada’s emissions come from our oil and gas sector. We need the leadership of these industries to decarbonize our country,” Trudeau said.

“That’s why we’ll make sure oil and gas emissions don’t increase and instead go down with achievable milestones,” while ensuring local economies can prosper.“

The Liberals are also introducing an interim electric vehicle mandate, which will require half the cars sold in Canada to be zero-emission by 2030, and because cleaning up electricity is critical to meeting climate pledges, the policy pairs with power-sector decarbonization, ahead of the final mandated target of 100 per cent by 2035.

Trudeau spoke in Cambridge, Ont., where protesters once again made an appearance amid a visible police presence. Officers carried one woman off the property when she refused to leave when asked.

Trudeau alluded to the protesters and their actions, which included sounding sirens and chanting expletives, as he defended his government’s record on climate change including progress in the electricity sector nationally, and touted its new plan.

“Sirens in the background may remind us that this is a climate emergency. That’s why we will move faster and be bolder,” he said.

Canada’s largest oilsands producers have already committed to reaching net zero greenhouse gas emissions by 2050, but the policy proposed Sunday “calls the oil companies’ bluff” by making those goals a legislated requirement, said Keith Stewart, senior energy strategist with Greenpeace Canada.

The new timeline for electric vehicles also “sends a clear signal to auto companies to get cracking (and build them here),” he said on Twitter, even as proposals like a fully renewable grid by 2030 are debated today. “We’d like to see this happen faster but the shift away from voluntary targets to requirements is big.”


Merran Smith, executive director of Clean Energy Canada, a climate program at Simon Fraser University, said clean electricity, clean transportation and “phasing out oil and gas with accountable milestones” must be key priorities over the next decade, aligning with Canada’s race to net-zero and the role of renewable energy.

“Today’s announcement, which checks all of these boxes, is not just good ambition_it’s good policy. Policy that will drive down carbon pollution and drive up clean job growth and economic competitiveness. It is policy that will drive Canada forward with cleaner cars, power Canada with clean electricity, and invest in businesses that will last such as battery manufacturing, electric vehicle manufacturing and low carbon steel,” Smith said in an email.

Michael Bernstein, executive director of the climate policy organization Clean Prosperity, said the promises laid out Sunday offer a “strong boost” to the federal government’s previous climate commitments.

He said the organization prefers market incentives such as carbon pricing, that spur innovation over further regulation. But since the largest oilsands companies have already committed to reaching net-zero emissions, he said the newly unveiled policy could provide some support.

“ First, I would encourage the Liberal Party to release independent modelling showing the types of emissions reductions they expect to achieve with their new package of policies. Second, many policies are referred to in general terms so I hope the Liberal Party will provide further details in the coming days,” he said.

“Finally, the document does not specifically mention carbon capture or carbon dioxide removal technologies but both technologies will be critical to achieve some of the pledges in today’s announcement, especially reaching net-zero emissions in the oil a gas sector.”

NDP Leader Jagmeet Singh painted the announcement as the latest in a string of “empty promises” from the Liberals on climate change, saying Canada has the highest increase in greenhouse gas emissions among all G7 countries, and that provinces like B.C. risk missing 2050 targets as well, he argued.

“Climate targets mean nothing when you don’t act on them. We can’t afford more of Justin Trudeau’s empty words on climate change,” he said in a statement.

The Trudeau Liberals submitted new targets to the United Nations in July, promising that Canada will curb emissions by 40 to 45 per cent from 2005 levels by 2030, building on the net-zero by 2050 plan announced earlier, officials say.

B.C. Streamlines Regulatory Process for Clean Energy Projects

BCER Renewable Energy Permitting streamlines single-window approvals for wind, solar, and transmission projects in BC, cutting red tape, aligning with CleanBC, and accelerating investment, Indigenous partnerships, and low-carbon infrastructure growth provincewide.

 

Key Points

BC's single-window framework consolidates approvals for wind, solar, and transmission to accelerate energy projects.

✅ Single-window permits via BC Energy Regulator (BCER)

✅ Covers wind, solar, and high-voltage transmission lines

✅ Aligns with CleanBC, supports Indigenous partnerships

 

In a decisive move to bolster clean energy initiatives, the government of British Columbia (B.C.) has announced plans to overhaul the regulatory framework governing renewable energy projects. This initiative aims to expedite the development of wind, solar, and other renewable energy sources, positioning B.C. as a leader in sustainable energy production.

Transitioning Regulatory Authority to the BC Energy Regulator (BCER)

Central to this strategy is the proposed legislation, set to be introduced in spring 2025, which will transfer the permitting and regulatory oversight of renewable energy projects, aligning with offshore wind regulation plans at the federal level, from multiple agencies to the BC Energy Regulator (BCER). This transition is designed to create a "single-window" permitting process, simplifying approvals and reducing bureaucratic delays for developers.

Expanding BCER's Mandate

Historically known as the British Columbia Oil and Gas Commission, the BCER's mandate has evolved to encompass a broader range of energy projects. The upcoming legislation will empower the BCER to oversee renewable energy projects, including wind and solar, as well as high-voltage transmission lines like the North Coast Transmission Line (NCTL), in step with renewable transmission planning efforts elsewhere in North America. This expansion aims to streamline the regulatory process, providing developers with a single point of contact throughout the project lifecycle.

Economic and Environmental Implications

The restructuring is expected to unlock significant economic opportunities. Projections suggest that the streamlined process could attract between $5 billion and $6 billion in private investment and complement recent federal grid modernization funding initiatives, generating employment opportunities and fostering economic growth. Moreover, by facilitating the rapid deployment of renewable energy projects, B.C. aims to enhance its clean energy capacity, contributing to global sustainability goals.

Strengthening Partnerships with Indigenous Communities

A pivotal aspect of this initiative is the emphasis on collaboration with Indigenous communities. The government has highlighted the importance of engaging First Nations in the development process, ensuring that projects are not only environmentally sustainable but also socially responsible. This approach seeks to honor Indigenous rights and knowledge, fostering partnerships that benefit all stakeholders.

Supporting Infrastructure Development

The acceleration of renewable energy projects necessitates corresponding infrastructure enhancements. The NCTL, for instance, is crucial for meeting the increased electricity demand from sectors such as mining, port electrification, and hydrogen production, and for addressing regional grid constraints that limit renewable integration. By improving the transmission infrastructure, B.C. aims to support the growing energy needs of these industries while promoting clean energy solutions.

Aligning with CleanBC Objectives

This regulatory overhaul aligns seamlessly with B.C.'s CleanBC initiative, which sets ambitious targets for reducing greenhouse gas emissions and promoting energy efficiency, and supports Canada's goal of zero-emissions electricity by 2035 under active consideration. By removing regulatory barriers and expediting project approvals, the government aims to accelerate the transition to a low-carbon economy, positioning B.C. as a hub for clean energy innovation.

Addressing Potential Challenges

While the initiative has been lauded for its potential, experts caution that careful consideration must be given to environmental assessments and Indigenous consultation processes, as well as to lessons from Alberta's solar expansion challenges on land use and grid impacts. Ensuring that projects meet environmental standards and respect Indigenous rights is crucial for the long-term success and acceptance of renewable energy developments.

The proposed changes mark a significant shift in B.C.'s approach to energy development, reflecting a commitment to sustainability and economic growth. As the legislation moves through the legislative process, stakeholders across the energy sector are closely monitoring developments, particularly as Alberta ends its renewables moratorium and resumes project approvals across the Prairies, anticipating a more efficient and transparent regulatory environment that supports the rapid expansion of renewable energy projects.

B.C.'s plan to streamline the regulatory process for clean energy projects represents a bold step toward a sustainable and prosperous energy future. By consolidating regulatory authority under the BCER, fostering Indigenous partnerships, and aligning with broader environmental objectives, the province is setting a precedent for effective governance in the transition to renewable energy.

Berlin Geothermal Plant in El Salvador Set to Launch This Year

El Salvador Geothermal Expansion boosts renewable energy with a 7 MW Berlin binary ORC plant, upgrades at Ahuachapan, and pipeline projects, strengthening clean power capacity, grid reliability, and sustainable growth in Central America.

 

Key Points

A national push adding binary-cycle capacity at Berlin and Ahuachapan, boosting geothermal supply and advancing sites.

✅ 7 MW Berlin binary ORC plant entering service.

✅ Ahuachapan upgrade adds 2 MW, total geothermal 204 MW.

✅ Next: Chinameca, San Miguel, San Vicente, World Bank backed.

 

El Salvador is set to expand its renewable energy capacity with the inauguration of the 7-MW Berlin binary geothermal power plant, slated to go online later this year. This new addition marks a significant milestone in the country’s geothermal energy development, highlighting its commitment to sustainable energy solutions. The plant, which has already been installed and is currently undergoing testing, is expected to boost the nation’s geothermal capacity, contributing to its growing renewable energy portfolio.

The Role of Geothermal Energy in El Salvador’s Energy Mix

Geothermal energy plays a pivotal role in El Salvador's energy landscape. With the combined output from the Ahuachapan and Berlin geothermal plants, geothermal energy now accounts for about 21% of the country's net electricity supply. This makes geothermal the second-largest source of energy generation in El Salvador, underscoring its importance as a reliable and sustainable energy resource alongside emerging options like advanced nuclear microreactor technologies in the broader low-carbon mix.

In addition to the Berlin plant, El Salvador has made significant improvements to its Ahuachapan geothermal power plant. Recent upgrades have increased its generation capacity by 2 MW, further enhancing the country’s geothermal energy output. Together, the Ahuachapan and Berlin plants bring the total installed geothermal capacity to 204 MW, positioning El Salvador as a regional leader in geothermal energy development.

The Berlin Binary Geothermal Plant: A Technological Milestone

The Berlin binary geothermal power plant is especially noteworthy for several reasons. It is the first geothermal power plant to be constructed in El Salvador since 2007, marking a significant step in the country's ongoing efforts to expand its renewable energy infrastructure while reinforcing attention to risk management in light of Hawaii geothermal safety concerns reported elsewhere. The plant utilizes a binary cycle geothermal system, which is known for its efficiency in extracting energy from lower temperature geothermal resources, making it an ideal solution for regions like Berlin, where geothermal resources are abundant but at lower temperatures.

The plant was built by Turboden, an Italian company specializing in organic Rankine cycle (ORC) technology. The binary cycle system operates by transferring heat from the geothermal fluid to a secondary fluid, which then drives a turbine to generate electricity. This system allows for the efficient use of geothermal resources that might otherwise be too low in temperature for traditional geothermal plants, enabling pairing with thermal storage demonstration solutions to optimize output.

Future Geothermal Developments in El Salvador

El Salvador is not stopping with the Berlin geothermal plant. The country is actively working on other geothermal projects, including those in Chinameca, San Miguel, and San Vicente. These developments are expected to add 50 MW of additional capacity in their first phase, reflecting a broader shift as countries pursue hydrogen-ready power plants to reduce emissions, with a second phase, supported by the World Bank, planned to add another 100 MW.

The Chinameca, San Miguel, and San Vicente projects represent the next wave of geothermal development in El Salvador. When completed, these plants will significantly increase the country’s geothermal capacity, further diversifying its energy mix and reducing reliance on fossil fuels, and will require ongoing grid upgrades, a task complicated elsewhere by Germany grid expansion challenges highlighted in Europe.

International Support and Collaboration

El Salvador’s geothermal development efforts are supported by various international partners, including the World Bank, which has been instrumental in financing the expansion of geothermal projects, as utilities such as SaskPower geothermal plans in Canada explore comparable pathways. This collaboration highlights the global recognition of El Salvador’s potential in geothermal energy and its efforts to position itself as a hub for geothermal energy development in Central America.

Additionally, the country’s expertise in geothermal energy, especially in binary cycle technology, has attracted international attention. El Salvador’s progress in the geothermal sector could serve as a model for other countries in the region that are looking to harness their geothermal resources to reduce energy costs and promote sustainable energy development.

The upcoming launch of the Berlin binary geothermal power plant is a testament to El Salvador’s commitment to sustainable energy. As the country continues to expand its geothermal capacity, it is positioning itself as a leader in renewable energy in the region. The binary cycle technology employed at the Berlin plant not only enhances energy efficiency but also demonstrates El Salvador’s ability to adapt and innovate within the renewable energy sector.

With the continued development of projects in Chinameca, San Miguel, and San Vicente, and ongoing international collaboration, El Salvador’s geothermal energy sector is set to play a crucial role in the country’s energy future. As global demand for clean energy grows, exemplified by U.S. solar capacity additions this year, El Salvador’s investments in geothermal energy are helping to build a more sustainable, resilient, and energy-independent future.
