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.

SaskPower Rate Hike 2022-2023 signals higher electricity rates in Saskatchewan as natural gas costs surge; the Rate Review Panel approved increases, affecting residential utility bills amid affordability concerns and government energy policy shifts.

Key Points

An 8% SaskPower electricity rate increase split 4% in Sept 2022 and 4% in Apr 2023, driven by natural gas costs.

✅ 4% increase Sept 1, 2022; +4% on Apr 1, 2023

✅ Panel-approved amid natural gas price surge and higher fuel costs

✅ Avg residential bill up about $5 per step; affordability concerns

The NDP Opposition is condemning the provincial government’s decision to approve the Saskatchewan Rate Review Panel’s recommendation to increase SaskPower’s rates for the first time since 2018, despite a recent 10% rebate pledge by the Sask. Party.

The Crown electrical utility’s rates will increase four per cent this fall, and another four per cent in 2023, a trajectory comparable to BC Hydro increases over two years. According to a government news release issued Thursday, the new rates will result in an average increase of approximately $5 on residential customers’ bills starting on Sept. 1, 2022, and an additional $5 on April 1, 2023.

“The decision to increase rates is not taken lightly and came after a thorough review by the independent Saskatchewan Rate Review Panel,” Minister Responsible for SaskPower Don Morgan said in a news release, amid Nova Scotia’s 14% hike this year. “World events have caused a significant rise in the price of natural gas, and with 42 per cent of Saskatchewan’s electricity coming from natural gas-fueled facilities, SaskPower requires additional revenue to maintain reliable operations.”

But NDP SaskPower critic Aleana Young says the rate hike is coming just as businesses and industries are struggling in an “affordability crisis,” even as Manitoba Hydro scales back a planned increase next year.

She called the announcement of an eight per cent increase in power bills on a summer day before the long weekend “a cowardly move” by the premier and his cabinet, amid comparable changes such as Manitoba’s 2.5% annual hikes now proposed.

“Not to mention the Sask. Party plans to hike natural gas rates by 17% just days from now,” said Young in a news release issued Friday, as Manitoba rate hearings get underway nearby. “If Scott Moe thinks his choices — to not provide Saskatchewan families any affordability relief, to hike taxes and fees, then compound those costs with utility rate hikes — are defensible, he should have the courage to get out of his closed-door meetings and explain himself to the people of this province.”

The province noted natural gas is the largest generation source in SaskPower’s fleet. As federal regulations require the elimination of conventional coal generation in Canada by 2030, SaskPower’s reliance on natural gas generation is expected to grow, with experts in Alberta warning of soaring gas and power prices in the region. Fuel and Purchased Power expense increases are largely driven by increased natural gas prices, and SaskPower’s fuel and purchased power expense is expected to increase from $715 million in 2020-21 to $1.069 billion in 2023-24. This represents a 50 per cent increase in fuel and purchased power expense over three years.

“In the four years since our last increase SaskPower has worked to find internal efficiencies, but at this time we require additional funding to continue to provide reliable and sustainable power,” SaskPower president & CEO Rupen Pandya said in the release “We will continue to be transparent about our rate strategy and the need for regular, moderate increases.”

CPUC Decision on San Diego Community Power directs SDG&E to use updated forecasts, stabilizing electricity rates for CCA customers and supporting clean energy in San Diego with accurate rate forecasting and reduced volatility.

Key Points

A CPUC ruling directing SDG&E to use updated forecasts to ensure accurate, stable CCA rates and limit volatility.

✅ Uses 2021 sales forecasts for rate setting

✅ Aims to prevent undercollection and bill spikes

✅ Levels changes across customer classes

The California Public Utilities Commission on Thursday sided with the soon-to-launch San Diego community energy program in a dispute it had with San Diego Gas & Electric.

San Diego Community Power — which will begin to purchase power for customers in San Diego, Chula Vista, La Mesa, Encinitas and Imperial Beach later this year — had complained to the commission that data SDG&E intended to use to calculate rates, including community choice exit fees that could make the new energy program less attractive to prospective customers.

SDG&E argued it was using numbers it was authorized to employ as part of a general rate case amid a potential rate structure revamp that is still being considered by the commission.

But in a 4-0 vote, the commission, or CPUC, sided with San Diego Community Power and directed SDG&E to use an updated forecast for energy sales.

"This was not an easy decision," said CPUC president Marybel Batjer at the meeting, held remotely due to COVID-19 restrictions. "In my mind, this outcome best accounts for the shifting realities ... in the San Diego area while minimizing the impact on ratepayers during these difficult financial times."

In filings to the commission, SDG&E predicted a rate decrease of 12.35 percent in the coming year. While that appears to be good news for customers, Californians still face soaring electricity prices statewide, Commissioner Martha Guzman Aceves said the data set SDG&E wanted to use would lead to an undercollection of $150 million to $260 million.

That would result in rates that would be "artificially low," Guzman Aceves said, and rates "would inevitably go up quite a bit after the undercollection was addressed."

San Diego Community Power, or SDCP, said the temporary reduction would make its rates less attractive than SDG&E's, especially amid SDG&E's minimum charge proposal affecting low-usage customers, just as it is about to begin serving customers. SDCP's board members wrote an open letter last month to the commission, accusing the utility of "willful manipulation of data."

Working with an administrative law judge at the CPUC, Guzman Aceves authored a proposal requiring SDG&E to use numbers based on 2021 forecasts, as regulators simultaneously weigh whether the state needs more power plants to ensure reliability. The utility argued that could result in an increase of "roughly 40 percent" for medium and large commercial and industrial customers this year.

To help reduce potential volatility, Guzman Aceves, SDCP and other community energy supporters called for using a formula that would average out changes in rates across customer classes amid debates over income-based utility charges statewide. That's what the commissioners OK'd Thursday.

"It is essential that customer commodity rates be as accurate as we can possibly get them to avoid undercollections," said Commissioner Genevieve Shiroma.

San Diego Community Power is one of 23 community choice aggregation, or CCA, energy programs that have launched in California in the past decade.

CCAs compete with traditional power companies amid California's evolving power competition landscape, in one important role — purchasing power for a given community. They were created to boost the use of cleaner energy sources, such as wind and solar, at rates equal to or lower than investor-owned utilities.

However, CCAs do not replace utilities because the incumbent power companies still perform all of the tasks outside of power purchasing, such as transmission and distribution of energy and customer billing.

When a CCA is formed, California rules stipulate the utility customers in that area are automatically enrolled in the CCA. If customers prefer to stay with their previous power company, they can opt out of joining the CCA.

The shift of customers from SDG&E to San Diego Community Power is expected to be large. The total number of accounts for SDCP is expected to be 770,000, which would make it the second-largest CCA in the state. That's why SDCP considered Thursday's CPUC decision to be so important.

"At a time when customers are choosing between sticking with San Diego Gas & Electric and migrating to a CCA, we want them to have accurate bill information," said Commissioner Clifford Rechtschaffen.

"SDCP is very happy with today's CPUC decision, and that the commissioners shared our goal of limiting rate volatility for businesses and families in the region," said SDCP interim CEO Bill Carnahan. "This is definitely a win for accurate rate forecasting, and our mutual customers, and we look forward to working with SDG&E on next steps."

In an email, SDG&E spokeswoman Helen Gao said, "We are committed to continuing to work collaboratively with local Community Choice Aggregation programs to support their successful launch in 2021 and ensure that our mutual customers receive excellent customer service."

San Diego Community Power's case before the CPUC was joined by the California Community Choice Association, a trade group advocating for CCAs, and the Clean Energy Alliance — the North County-based CCA representing Del Mar, Solana Beach and Carlsbad that is scheduled to launch this summer.

SDCP will begin its rollout this year, folding in about 71,000 municipal, commercial and industrial accounts. The bulk of its roughly 700,000 residential accounts is expected to come in January 2022.

Iran Electricity Exports to Iraq address power shortages and blackouts, supplying 1,200-1,500 MW and gas for 2,500 MW, amid sanctions, aging grid losses, rising peak demand, and TAVANIR plans to expand cross-border energy capacity.

Key Points

Energy flows from Iran supply Iraq with 1,200-1,500 MW plus gas yielding 2,500 MW, easing shortages and blackouts.

✅ 1,200-1,500 MW direct power; gas adds 2,500 MW generation

✅ Iraq exempt on Iranian gas, but faces US pressure

✅ Aging grid loses 25%; $30B upgrades needed

“Iran exports 1,200 megawatts to 1,500 megawatts of electricity to Iraq per day, reflecting broader regional power trade dynamics, as Iraq is dealing with severe power shortages and frequent blackouts,” Hamid Hosseini said.

As he added, Iran also exports 37 million to 38 million cubic meters of gas to the country, much of it used in combined-cycle power plants to save energy and boost generation.

On September 11, Iraq’s electricity minister, Luay al Khateeb, said the country needs Iranian gas to generate electricity for the next three or four years, as energy cooperation discussions continue between Baghdad and Tehran.

Iraq was exempted from sanctions concerning Iranian gas imports; however, the U.S. has been pressing all countries to stop trading with Tehran.

Iraq's population has been protesting to authorities over power cuts. Iran exports 1,200 megawatts of direct power supplies and its gas is converted into 2,500 MW of electricity. According to al Khateeb, the current capacity is 18,000 MW, with peak demand of 25,000 MW possible during the hot summer months when consumption surges, a figure that rises every year.

Any upgrades would need investment of at least $30 billion, with grid rehabilitation efforts underway to modernize infrastructure, as the grid is 50 years old and loses 25 percent of its capacity due to Isis attacks.

In late July, Managing Director of Gharb (West) Regional Electricity Company Ali Asadi said Iran has high capacity and potential to export electricity up to twofold of the current capacity to neighboring Iraq, as it eyes transmitting electricity to Europe to serve as a regional hub as well.

He pointed to the new strategy of Iran Power Generation, Transmission & Distribution Management Company (TAVANIR) for increasing electricity export to neighboring Iraq and reiterated, “the country enjoys high potential to export 1,200 megawatts electricity to neighboring Iraq,” while Iraq is also exploring nuclear power plants to tackle electricity shortages.

Texas After-Labor Day School Start could ease ERCOT's power grid strain by shifting peak demand, lowering air-conditioning loads in schools, improving grid reliability, reducing electricity costs, and curbing emissions during extreme heat the summer months.

Key Points

A proposed calendar shift to start school after Labor Day to lower ERCOT peak demand, costs, and grid risk.

✅ Cuts school HVAC loads during peak summer heat

✅ Lowers costly peaker plant use and electricity rates

✅ Requires calendar changes, testing and activities shifts

As Texas faces increasing demands on its power grid, a new proposal is gaining traction: starting the school year after Labor Day. This idea, reported by the Dallas News, suggests that delaying the start of the academic year could help alleviate some of the pressure on the state’s electricity grid during the peak summer months, potentially leading to both grid stability and financial savings. Here’s an in-depth look at how this proposed change could impact Texas’s energy landscape and education system.

The Context of Power Grid Strain

Texas's power grid, operated by the Electric Reliability Council of Texas (ERCOT), has faced significant challenges in recent years. Extreme weather events, record-breaking temperatures, and high energy demand have strained the grid, and some analyses argue that climate change, not demand is the biggest challenge today, leading to concerns about reliability and stability. The summer months are particularly taxing, as the demand for air conditioning surges, often pushing the grid to its limits.

In this context, the idea of adjusting the school calendar to start after Labor Day has been proposed as a potential strategy to help manage electricity demand. By delaying the start of school, proponents argue that it could reduce the load on the power grid during peak usage periods, thereby easing some of the stress on energy resources.

Potential Benefits for the Power Grid

The concept of delaying the school year is rooted in the potential benefits for the power grid. During the hottest months of summer, the demand for electricity often spikes as families use air conditioning to stay cool, and utilities warn to prepare for blackouts as summer takes hold. School buildings, typically large and energy-intensive facilities, contribute significantly to this demand when they are in operation.

Starting school later could help reduce this peak demand, as schools would be closed during the hottest months when the grid is under the most pressure. This reduction in demand could help prevent grid overloads and reduce the risk of power outages, at a time when longer, more frequent outages are afflicting the U.S. power grid, ultimately contributing to a more stable and reliable electricity supply.

Additionally, a decrease in peak demand could help lower electricity costs. Power plants, particularly those that are less efficient and more expensive to operate, are often brought online during periods of high demand. By reducing the peak load, the state could potentially minimize the need for these costly power sources, leading to lower overall energy costs.

Financial and Environmental Considerations

The financial implications of starting school after Labor Day extend beyond just the power grid. By reducing energy consumption during peak periods, the state could see significant savings on electricity costs. This, in turn, could lead to lower utility bills for schools, businesses, and residents alike, a meaningful relief as millions risk electricity shut-offs during summer heat.

Moreover, reducing the demand for electricity from fossil fuel sources can have positive environmental impacts. Lower peak demand may reduce the reliance on less environmentally friendly energy sources, and aligns with calls to invest in a smarter electricity infrastructure nationwide, thereby decreasing greenhouse gas emissions and contributing to overall environmental sustainability.

Challenges and Trade-offs

While the proposal offers potential benefits, it also comes with challenges and trade-offs. Adjusting the school calendar would require significant changes to the academic schedule, potentially affecting extracurricular activities, summer programs, and family plans, and comparisons to California's reliability challenges underscore the complexity. Additionally, there could be resistance from various stakeholders, including parents, educators, and students, who are accustomed to the current school calendar.

There are also logistical considerations to address, such as how a delayed start might impact standardized testing schedules and the academic calendar for higher education institutions. These factors would need to be carefully evaluated to ensure that the proposed changes do not adversely affect educational outcomes or create unintended consequences.

Looking Ahead

The idea of starting Texas schools after Labor Day represents an innovative approach to addressing the challenges facing the state’s power grid. By potentially reducing peak demand and lowering energy costs, and alongside efforts to connect Texas's grid to the rest of the nation, this proposal could contribute to greater grid stability and financial savings. However, careful consideration and planning will be essential to navigate the complexities of altering the school calendar and to ensure that the benefits outweigh the challenges.

As Texas continues to explore solutions for managing its power grid and energy resources, the proposal to shift the school year schedule provides an intriguing possibility. It reflects a broader trend of seeking creative and multifaceted approaches to balancing energy demand, environmental sustainability, and public needs.

In conclusion, starting schools after Labor Day could offer tangible benefits for Texas’s power grid and financial well-being. As discussions on this proposal advance, it will be important to weigh all factors and engage stakeholders to ensure a successful and equitable implementation.

Washington EV Rebate Program drives EV adoption with incentives, funding, and clean energy goals, cutting greenhouse gas emissions. Residents embrace electric vehicles as charging infrastructure expands, supporting sustainable transportation and state climate targets.

Key Points

Washington EV Rebate Program provides incentives to cut EV costs, accelerate adoption, and support clean energy targets.

✅ Over half of allocated funding already utilized statewide.

✅ Incentives lower upfront costs and spur EV demand.

✅ Charging infrastructure expansion remains a key priority.

Washington State has reached a significant milestone in its electric vehicle (EV) rebate program, with more than half of the allocated funding already utilized. This rapid uptake highlights the growing interest in electric vehicles as residents seek more sustainable transportation options. As the state continues to prioritize environmental initiatives, this development showcases both the successes and challenges of promoting electric vehicle adoption.

A Growing Demand for Electric Vehicles

The substantial drawdown of rebate funds indicates a robust demand for electric vehicles in Washington. As consumers become increasingly aware of the environmental benefits associated with EVs—such as reduced greenhouse gas emissions and improved air quality—more individuals are making the switch from traditional gasoline-powered vehicles. Additionally, rising fuel prices and advancements in EV technology, alongside zero-emission incentives are further incentivizing this shift.

Washington's rebate program, which offers financial incentives to residents who purchase or lease eligible electric vehicles, plays a critical role in making EVs more accessible. The program helps to lower the upfront costs associated with purchasing electric vehicles, and similar approaches like New Brunswick EV rebates illustrate how regional incentives can boost adoption, thus encouraging more drivers to consider these greener alternatives. As the state moves toward its goal of a more sustainable transportation system, the popularity of the rebate program is a promising sign.

The Impact of Funding Utilization

With over half of the rebate funding already used, the program's popularity raises questions about the sustainability of its financial support and the readiness of state power grids to accommodate rising EV demand. Originally designed to spur adoption and reduce barriers to entry for potential EV buyers, the rapid depletion of funds could lead to future challenges in maintaining the program’s momentum.

The Washington State Department of Ecology, which oversees the rebate program, will need to assess the current funding levels and consider future allocations to meet the ongoing demand. If the funds run dry, it could slow down the adoption of electric vehicles, potentially impacting the state’s broader climate goals. Ensuring a consistent flow of funding will be essential for keeping the program viable and continuing to promote EV usage.

Environmental Benefits and Climate Goals

The increasing adoption of electric vehicles aligns with Washington’s ambitious climate goals, including a commitment to reduce carbon emissions significantly by 2030. The state aims to transition to a clean energy economy and has set a target for all new vehicles sold by 2035 to be electric, and initiatives such as the hybrid-electric ferry upgrade demonstrate progress across the transportation sector. The success of the rebate program is a crucial step in achieving these objectives.

As more residents switch to EVs, the overall impact on air quality and carbon emissions can be profound. Electric vehicles produce zero tailpipe emissions, which contributes to improved air quality, particularly in urban areas that struggle with pollution. The transition to electric vehicles can also help to reduce dependence on fossil fuels, further enhancing the state’s sustainability efforts.

Challenges Ahead

While the current uptake of the rebate program is encouraging, there are challenges that need to be addressed. One significant issue is the availability of EV models. Although the market is expanding, not all consumers have equal access to a variety of electric vehicle options. Affordability remains a barrier for many potential buyers, especially in lower-income communities, but targeted supports like EV charger rebates in B.C. can ease costs for households. Ensuring that all residents can access EVs and the associated incentives is vital for equitable participation in the transition to electric mobility.

Additionally, there are concerns about charging infrastructure. For many potential EV owners, the lack of accessible charging stations can deter them from making the switch. Expanding charging networks, particularly in underserved areas, is essential for supporting the growing number of electric vehicles on the road, and B.C. EV charging expansion offers a regional model for scaling access.

Looking to the Future

As Washington continues to advance its electric vehicle initiatives, the success of the rebate program is a promising indication of changing consumer attitudes toward sustainable transportation. With more than half of the funding already used, the focus will need to shift to sustaining the program and ensuring that it meets the needs of all residents, while complementary incentives like home and workplace charging rebates can amplify its impact.

Ultimately, Washington’s commitment to electric vehicles is not just about rebates; it’s about fostering a comprehensive ecosystem that supports clean energy, infrastructure, and equitable access. By addressing these challenges head-on, the state can continue to lead the way in the transition to electric mobility, benefiting both the environment and its residents in the long run.
