Construction on Manitoba's largest wind farm is now underway near the community of St. Joseph in southern Manitoba.

A ceremony to mark the official groundbreaking for the project was held April 29, during which time area landowners were also given their first payments as part of the deal between the provincial government and San Francisco-based Pattern Energy Group.

"Today we celebrate the start of construction on Manitoba's second wind farm and we also celebrate the expansion of renewable energy sources in Manitoba," said Finance Minister Rosann Wowchuk, minister responsible for Manitoba Hydro.

"This wind farm will more than double wind capacity in the province."

The announcement follows the successful negotiation of a 27-year power-purchase agreement between Hydro and Pattern Energy, signed late last month.

The deal will see Pattern Energy invest $95 million in the 138-megawatt wind farm, located about 100 kilometres south of Winnipeg. Manitoba Hydro will loan Pattern Energy up to $260 million, which is to be repaid over 20 years.

When finished in the spring of 2011, there will be 60 wind turbines covering an area of 125 square kilometres in the rural municipalities of Montcalm and Rhineland.

Pattern expects the first turbines will be running by year's end.

At full capacity, it will produce enough electricity to serve the needs of 50,000 homes.

Pattern is expected to pay an estimated $38 million in total to landholders and an additional $44 million in local municipal taxes over the life of the project.

Manitoba's other wind farm is located near St. Leon, about 125 kilometres southwest of Winnipeg. The 100-megawatt farm became operational in 2006.

Texas's new set of electricity regulators begins to take shape in wake of deep freeze, power outages

Texas PUC Appointments signal post-storm reform as Gov. Greg Abbott taps Peter Lake and advances Will McAdams for Senate confirmation, affecting ERCOT oversight, grid reliability, wholesale power pricing, and securitization for co-ops.

 

Key Points

Texas PUC appointments add Peter Lake and Will McAdams to steer ERCOT, grid reliability, and market policy.

✅ Peter Lake nominated chair to replace Arthur D'Andrea.

✅ Will McAdams advances toward Senate confirmation.

✅ Focus on ERCOT oversight, price cap debate, grid resilience.

 

A new set of Texas electricity regulators began to take shape Monday, as Gov. Greg Abbott nominated a finance expert to be the next chairman of the Public Utility Commission while his earlier choice of a PUC member moved toward Senate confirmation.

The Republican governor put forward Peter Lake of Austin, who has spent more than five years as an Abbott appointee to the Texas Water Development Board, as his second commission pick in as many weeks.

“I am confident he will bring a fresh perspective and trustworthy leadership to the PUC,” Abbott said of Lake, who once worked as a trader of futures and derivatives for a firm belonging to the Chicago Mercantile Exchange and more recently has eagerly promoted bonds for the State Water Implementation Fund for Texas.

“Peter’s expertise in the Texas energy industry and business management will make him an asset to the agency,” Abbott, who has touted grid readiness in recent months, said in a written statement. “I urge the Senate to swiftly confirm Peter’s appointment.”

On Monday, the Senate appeared to be moving quickly to confirm Abbott’s April 1 selection for the PUC, Will McAdams, president of Associated Builders and Contractors of Texas and a former legislative aide who helped write policy for regulated industries such as electricity.

McAdams was among the 129 nominees that the Senate Nominations Committee voted out, 8-0. His nomination heads now to the Senate floor.

All three of Abbott’s handpicked PUC commissioners who were in place before and during February’s calamitous winter storm have since quit or said they’re resigning, even as Sierra Club criticism of Abbott's demands intensified in the aftermath.

February’s polar vortex left in its wake physical and financial wreckage after a nonprofit grid operator answering to the PUC, amid calls for market reforms to avoid blackouts, shut off electricity to more than 4 million Texans, causing the deaths of at least 125 people, 13 of them in the Dallas-Fort Worth area.

Gov. Greg Abbott on Thursday named Will McAdams to the embattled Public Utility Commission of Texas. McAdams is a construction industry lobbyist with strong ties to the GOP-controlled Legislature. In Feb. 17 file photo, winter storm's snowfall andn large electrical transmission lines in South Arlington are pictured.

In a 45-minute confirmation hearing, McAdams, as lawmakers discussed ways to improve electricity reliability statewide, drew praise – and few tough questions.

McAdams, who previously worked for three GOP senators, testified that had he been on the commission in February, he would not have kept in place a controversial, $9,000-per-megawatt hour price cap on wholesale power for about 32 hours on Feb. 18-19.

“I don’t see myself making that decision,” he said.

McAdams, though, hedged slightly, saying he’s not privy to all information that the Electric Reliability Council of Texas, or ERCOT, and the PUC may have had at their disposal during the crisis.

The comments were notable because Lt. Gov. Dan Patrick and the Senate have fought with Abbott and the House over $16 billion in overcharges that, according to an independent market monitor, wrongly accrued near the end of the Feb. 15-19 outages.

Sen. Charles Schwertner, R-Georgetown, said the commission’s former chairwoman, DeAnn Walker, and Bill Magness, president of ERCOT, decided to hold the high cap in place because there “was still great concern about grid stability, even though there was significant reserves.”

He pressed McAdams to call that incorrect, which McAdams did.

“Given the fact pattern that I’m privy to, senator,” it wasn’t the right move, he said. “But again, there may be other facts out there. There probably are.”

McAdams acknowledged many homeowners and businesses were traumatized.

“The public’s confidence in the ability of the PUC to effectively regulate our electric markets has been badly damaged and shaken,” he said.

McAdams spoke favorably of renewable energy, calling wind and solar “absolutely valuable resources,” as the electricity sector faces profound change nationwide. To whatever extent those are not available, the PUC should “firm that up” with “dispatchable forms of generation,” such as gas, coal and nuclear, McAdams said.

He also called for lawmakers to consider providing electricity market bailout through “securitization,” or low-interest bond financing, to rural electric co-ops that were unable to pay the massive wholesale power bills they racked up during the February crisis.

“It would prevent those systems from having to front-load those costs onto their own members and smooth that out over a term of years,” while preventing an “uplift” of costs to other market participants who wisely hedged against soaring prices, McAdams said.

Noting that more than 400 bills have been filed to change ERCOT and how it’s governed, and as Texans prepare to vote on grid modernization funding this year, McAdams told the Senate panel, “It is clear to me that the Legislature wants meaningful changes to the status quo – to ensure that something positive comes out of this tragedy.”

Lake, who if confirmed by the Senate would replace Arthur D’Andrea as PUC chairman, grew up in Tyler. He attended prep school in New England and earned an undergraduate degree from the University of Chicago and a master of business administration degree from Stanford University.

He then worked for a commodities trading firm, a behavioral health company and as a business consultant before he became director of business development for Tyler-based Lake Ronel Oil Co. in 2014.

In late 2015, Abbott named Lake to the Texas Water Development Board and in February 2018 picked him to be the chairman of the three-member board that seeks to ensure water supplies for a fast-growing state.

Lake has steered the water board as it rolled out additional loans for water projects, approved by the Legislature and voters in 2013, and took the lead after Hurricane Harvey on flood control planning and infrastructure financing.

He’s posted exuberantly on Twitter as he toured agricultural water installations, lakes in West Texas and river authorities.

If confirmed, Lake and McAdams each would make $189,500 a year.

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.

Victims of California's mega-fire will sue electricity company

PG&E Wildfire Lawsuit alleges utility negligence, inadequate infrastructure maintenance, and faulty transmission lines, as victims seek compensation. Regulators investigate the blaze, echoing class actions after Victoria's Black Saturday mega-fires and utility oversight failures.

 

Key Points

PG&E Wildfire Lawsuit alleges utility negligence and power line faults, seeking victim compensation amid investigations.

✅ Alleged failure to maintain transmission infrastructure

✅ Spark reports and regulator filings before blaze erupted

✅ Class action parallels with Australia's Black Saturday

 

Victims of California's most destructive wildfire have filed a lawsuit accusing Pacific Gas & Electric Co. of causing the massive blaze, a move that follows the utility's 2018 Camp Fire guilty plea in a separate case.

The suit filed on Tuesday in state court in California accuses the utility of failing to maintain its infrastructure and properly inspect and manage its power transmission lines, amid prior reports that power lines may have sparked fires in California.

The utility's president said earlier the company doesn't know what caused the fire, but is cooperating with the investigation by state agencies, and other utilities such as Southern California Edison have faced wildfire lawsuits in California.

PG&E told state regulators last week that it experienced a problem with a transmission line in the area of the fire just before the blaze erupted.

A landowner near where the blaze began said PG&E notified her the day before the wildfire that crews needed to come onto her property because some wires were sparking, and the company later promoted its wildfire assistance program for victims seeking aid.

A massive class action after Australia's last mega-fire, Victoria's Black Saturday in 2009, saw $688.5 million paid in compensation to thousands of claimants affected by the Kilmore-Kinglake and Murrindindi-Marysville fires, partly by electricity company SP Ausnet, and partly by government agencies, while in California PG&E's bankruptcy plan won support from wildfire victims addressing compensation claims.

N.S. joins Western Climate Initiative for tech support for emissions plan

Nova Scotia Cap-and-Trade Program joins Western Climate Initiative to leverage emissions trading IT systems, track allowances, and manage compliance, while setting in-province caps, carbon pricing signals, and third-party verified reporting for industrial and fuel suppliers.

 

Key Points

A provincial emissions trading system using WCI services to cap GHGs, track allowances, and enforce verified compliance.

✅ Uses WCI IT system to manage allowances and registry

✅ Initial trading limited to in-province participants

✅ Third-party verification and annual reporting deadlines

 

Nova Scotia is yet to set targets for its new cap and trade regime to reduce greenhouse gases, but the province announced Monday that it has joined the Western Climate Initiative Inc. -- a non-profit corporation formed to provide administrative and technical services to states and provinces with emissions trading programs.

Environment Minister Iain Rankin said joining the initiative would allow the province to use its IT system to manage and track its new cap and trade program.

Rankin said the province can join without trading greenhouse gas emission allowances with other jurisdictions -- California, Quebec, and Ontario are currently linked through the program, with Hydro-Québec's U.S. sales highlighting cross-border dynamics. Nova Scotia currently has no plans to trade outside the province as it works on emissions caps Rankin said will be ready sometime in June.

Nova Scotia is yet to set targets for its new cap and trade regime to reduce greenhouse gases, but the province announced Monday that it has joined the Western Climate Initiative Inc. -- a non-profit corporation formed to provide administrative and technical services to states and provinces with emissions trading programs.

Environment Minister Iain Rankin said joining the initiative would allow the province to use its IT system to manage and track its new cap and trade program.

Rankin said the province can join without trading greenhouse gas emission allowances with other jurisdictions -- California, Quebec, and Ontario are currently linked through the program. Nova Scotia currently has no plans to trade outside the province as it works on emissions caps Rankin said will be ready sometime in June.

"By keeping our system internal it ensures that our greenhouse gas reductions are happening within our province," said Rankin. "But we do have that opportunity (to join) and if there are new entrants or we need more access to credits then that may shift our strategy."

The use of the system will cost Nova Scotia about US$314,000 for 2018-19, with an annual cost in subsequent years of about US$228,000 or more, if the province requests modifications.

"If we were to do something like that internally we would have to build a full database and hire more people, so this was an obvious choice for us," said Rankin.

Nova Scotia has already met the national reduction target of 30 per cent below 2005 levels and says it's on track to have 40 per cent of electricity generation from renewables by 2020, underscoring how cleaning up Canada's electricity supports climate pledges.

Stephen Thomas, energy campaign coordinator for the Ecology Action Centre, called the province's move an "important small step," stressing the importance of using the same administrative rules as the other jurisdictions involved.

But Thomas said Nova Scotia should go further and trade emissions with California, Quebec, and Ontario, and also put a price on carbon by auctioning credits as they do.

Thomas said Nova Scotia's system stands to be volatile because of the smaller number of participants -- about 20 including Nova Scotia Power, Northern Pulp, Lafarge, and large oil and gasoline companies such as ExxonMobil, Imperial and Irving.

"It's very likely to favour Nova Scotia Power as the largest single emitter with the most credits to sell here, and that would change if we had a linked system, at a time when Canada will need more electricity to hit net-zero according to the IEA," Thomas said.

He said it's important to have a linked system and a regional approach in Atlantic Canada, which has more emissions per person and more emissions per GDP than places like Ontario, Quebec and California, and where policies like Newfoundland's rate reduction plan can influence electricity strategy.

"Reducing emissions, because we are so emissions-intensive here, is a little bit cheaper," said Thomas. "So it's possible that Ontario, Quebec and California could pay Nova Scotia to reduce its emissions."

Under its program, Nova Scotia requires industrial facilities generating 50,000 tonnes or more of greenhouse gas emissions per year to report emissions.

Regulations also cover petroleum product suppliers that import or produce 200 litres of fuel or more per year for consumption and natural gas distributors whose products produce at least 10,000 tonnes of greenhouse gas emissions a year.

Companies were to have reported to the Environment Department by May 1 but Rankin said the deadline has been pushed back to June 1, a deadline that was to be followed in subsequent years in any event. Reports must be verified by a third party by Sept. 1 every year.

The Liberal government passed enabling legislation for cap and trade last fall.

As for the upcoming emissions caps, Rankin isn't tipping the province's hand yet, even as B.C.'s 2050 targets face a shortfall in some forecasts.

"Those caps will recognize the investments that have already been made and therefore will be the most cost-effective program that we can put together to meet the federal requirement," he said.

'Unlayering' peak demand could accelerate energy storage adoption

Duration Portfolio Energy Storage aligns layered peak demand with right-sized batteries, enabling peak shaving, gas peaker replacement, and solar-plus-storage synergy while improving grid flexibility, reliability, and T&D deferral through two- to four-hour battery durations.

 

Key Points

An approach that layers battery durations to match peaks, cut costs, replace peakers, and boost grid reliability.

✅ Layers 2- to 4-hour batteries by peak duration

✅ Enables solar-plus-storage and peak shaving

✅ Cuts T&D upgrades, emissions, and fuel costs

 

The debate over energy storage replacing gas-fired peakers has raged for years, but a new approach that shifts the terms of the argument could lead to an acceleration of storage deployments.

Rather than looking at peak demand as a single mountainous peak, some analysts now advocate a layered approach that allows energy storage to better match peak needs and complement ongoing efforts to improve solar and wind power across the grid.

"You don’t have to have batteries that run to infinity."

Some developers of solar-plus-storage projects, bolstered by cheap batteries, say they can already compete head-to-head with gas-fired peakers. "I can beat a gas peaker anywhere in the country today with a solar-plus-storage power plant," Tom Buttgenbach, president and CEO of developer 8minutenergy Renewables, recently told S&P Global.

Customers are very busy these days and rebate programs need to fit the speed of their life. Participation should be quick, easy, and accessible anywhere.

Others disagree. Storage is not disruptive for generation, but will be disruptive for transmission and distribution, Kris Zadlo, executive vice president and chief development officer at Invenergy, told the audience at a Bloomberg New Energy Finance conference last spring. Invenergy, like many renewable power developers, develops generation, energy storage and transmission projects.

But there is another path that avoids the pitfalls of positions on either end of the all-or-none approach. "Do the analysis of the need itself," Ray Hohenstein, market applications director at Fluence, told Utility Dive. If the need is only two hours in duration, it may be best served by a two-hour battery. "You don’t have to have batteries that run to infinity."

 

Storage vs. fossil fuel peakers

Energy storage has several benefits over traditional fossil fuel peaking plants, Hohenstein said. It is instantaneous, it has no emissions and requires no fuel, and has limited infrastructure needs. It can also help the grid absorb higher levels of renewable generation by soaking up excess output, such as solar power at noon, and many planned storage additions will be paired with solar in the next few years. But the one thing energy storage cannot do, he said, is provide limitless energy.

So, instead of looking at replacing an individual peaker, Hohenstein advocated a "duration portfolio" approach that uses energy storage to shave peak load.

If the need is for 150 MW of resources that will never need to run for more than two hours at a time, then a battery is "quite cheap," significantly less than a four or eight-hour battery, said Hohenstein. "If you fill up your peak by duration layer, it could be more cost effective."

 

NREL research driver

Fluence’s approach is informed by research by Paul Denholm and Robert Margolis at the National Renewable Energy Laboratory (NREL), released last spring.

The NREL researchers looked at the California market where they said 11 GW of fossil fuel capacity is expected to be retired by 2029 because of new once-through-cooling requirements that are taking effect. A lot of that capacity is peaking capacity and, according to NREL’s analysis, a large fraction could be replaced with four-hour energy storage, assuming continued storage cost reductions and growth in solar installations.

The key in NREL’s research was the level of solar power penetration. There is a "synergistic" relationship between solar penetration and storage deployment, the researchers wrote, and other studies suggest wind and solar could meet 80% of U.S. demand as these trends continue.

Ireland goes 25 days without using coal to generate electricity

Ireland Coal-Free Electricity Record: EirGrid reports 25 days without coal on the all-island grid, as wind power, renewables, and natural gas dominated generation, cutting CO2 emissions, with Moneypoint sidelined by market competitiveness.

 

Key Points

It is a 25-day period when the grid used no coal, relying on gas and renewables to reduce CO2 emissions.

✅ 25 days coal-free between April 11 and May 7

✅ Gas 60%, renewables 30% of generation mix

✅ Eurostat: 6.8% drop in Ireland's CO2 emissions

 

The island of Ireland has gone a record length of time without using coal-fired electricity generation on its power system, Britain's week-long coal-free run providing a recent comparator, Eirgrid has confirmed.

The all-island grid operated without coal between April 11th and May 7th – a total of 25 days, it confirmed. This is the longest period of time the grid has operated without coal since the all-island electricity market was introduced in 2007, echoing Britain's record coal-free stretch seen recently.

Ireland’s largest generating station, Moneypoint in Co Clare, uses coal, with recent price spikes in Ireland fueling concerns about dispatchable capacity, as do some of the larger generation sites in Northern Ireland.

The analysis coincides with the European statistics agency, Eurostat publishing figures showing annual CO2 emissions in Ireland fell by 6.8 per cent last year; partly due to technical problems at Moneypoint.

Over the 25-day period, gas made up 60 per cent of the fuel mix, while renewable energy, mainly wind, accounted for 30 per cent, echoing UK wind surpassing coal in 2016 across the market. Coal-fired generation was available during this period but was not as competitive as other methods.

EirGrid group chief executive Mark Foley said this was “a really positive development” as coal was the most carbon intense of all electricity sources, with its share hitting record lows in the UK in recent years.

“We are acutely aware of the challenges facing the island in terms of meeting our greenhouse gas emission targets, mindful that low-carbon generation stalled in the UK in 2019, through the deployment of more renewable energy on the grid,” he added.

Last year 33 per cent of the island’s electricity came from renewable energy sources, German renewables surpassing coal and nuclear offering a parallel milestone, a new record. Coal accounted for 9 per cent of electricity generation, down from 12.9 per cent in 2017.
