GE Hitachi Nuclear Energy said it has submitted the revised design documents for its Economic Simplified Boiling Water Reactor (ESBWR) to the U.S. Nuclear Regulatory Commission.

GE Hitachi said the submission marks a milestone in the company's effort to move forward with the 1,520-megawatt design which two U.S. utilities have selected to use for two new nuclear plants, some of the first reactors proposed after a three-decade lapse in U.S. nuclear expansion.

Two other U.S. utilities dropped the ESBWR design fearing that the time needed to obtain NRC certification would slow their efforts to pursue construction of new reactors.

GE Hitachi, a venture of General Electric Co and Hitachi Ltd, said that the ESBWR design's advanced safety features and cost-saving advantages "are key in delivering the next generation of nuclear reactors worldwide."

Nuclear reactors generate about 20 percent of U.S. electricity and proponents say nuclear power is attractive because it emits none of the heat-trapping carbon dioxide that comes from power plants that burn coal and natural gas.

"As the United States debates energy policy, nuclear power should play a pivotal role, as nuclear generates virtually carbon-free electricity," said Jack Fuller, chief executive of the GE Hitachi alliance.

Detroit Edison of Michigan and Dominion Energy of Virginia have submitted construction license applications using the ESBWR technology. NuStart Energy, a U.S. Energy Department-supported consortium, also supported the ESBWR design.

Exelon Corp, the largest U.S. nuclear operator, dropped the ESBWR technology last year for a proposed new reactor in Texas while Entergy Corp suspended its NRC license application after being unable to reach agreement with GE Hitachi Nuclear on commercial terms for a proposed new plant in the Southeast.

Exelon called the ESBWR design "promising," while Entergy said its decision was not a criticism of the design.

Wilmington, North Carolina-based GE Hitachi Nuclear has two nuclear designs, the ESBWR and the 1,350-MW Advanced Boiling Water Reactor (ABWR) design which was certified by the NRC in 1997 and is operating in Japan.

Compared with typical U.S. nuclear reactors operating now, GE Hitachi said the ABWR and ESBWR designs are expected to have 30 to 40 percent lower operating and maintenance costs per kilowatt-hour thanks to an increased capacity factor and simpler systems.

B.C. residents and businesses get break on electricity bills for three months

BC Hydro COVID-19 Bill Relief offers pandemic support with bill credits, rate cuts, and deferred payments for residential, small business, and industrial customers across B.C., easing utilities costs during COVID-19 economic hardship.

 

Key Points

COVID-19 bill credits, a rate cut, and deferred payments for eligible B.C. homes, small businesses, and industrial customers.

✅ Non-repayable credits equal to 3 months of average bills.

✅ Small businesses closed can skip bills for three months.

✅ Large industry may defer 50% of electricity costs.

 

B.C. residents who have lost their jobs or had their wages cut will get a three-month break on BC Hydro bills, while small businesses, amid commercial consumption plummets during COVID-19, are also eligible to apply for similar relief.

Premier John Horgan said Wednesday the credit for residential customers will be three times a household’s average monthly bill over the past year and does not have to be repaid as part of the government’s support package during the COVID-19 pandemic, as BC Hydro demand down 10% highlights the wider market pressures.

He said small businesses that are closed will not have to pay their power bills for three months, and in Ontario an Ontario COVID-19 hydro rebate complemented similar relief, and large industrial customers, including those operating mines and pulp mills, can opt to have 50 per cent of their electricity costs deferred, though a deferred costs report warned of long-term liabilities.

BC Hydro rates will be cut for all customers by one per cent as of April 1, a move similar to Ontario 2021 rate reductions that manufacturers supported lower rates at the time, after the B.C. Utilities Commission provided interim approval of an application the utility submitted last August.

Eligible residential customers can apply for bill relief starting next week and small business applications will be accepted as of April 14, while staying alert to BC Hydro scam attempts during this period, with the deadline for both categories set at June 30.

Will Israeli power supply competition bring cheaper electricity?

Israel Electricity Reform Competition opens the supply segment to private suppliers, challenges IEC price controls, and promises consumer choice, marginal discounts, and market liberalization amid natural gas generation and infrastructure remaining with IEC.

 

Key Points

Policy opening 40% of supply to private vendors, enabling consumer choice and small discounts while IEC retains the grid.

✅ 40% of retail supply opened to private electricity suppliers

✅ IEC keeps meters, lines; tariffs still regulated by the authority

✅ Expected discounts near 7%, not dramatic price cuts initially

 

"See the pseudo-reform in the electricity sector: no lower prices, no opening the market to competition, and no choice of electricity suppliers, with a high rate for consumers despite natural gas." This is an advertisement by the Private Power Producers Forum that is appearing everywhere: Facebook, the Internet, billboards, and the press.

Is it possible that the biggest reform in the economy with a cost estimated by Israel Electric Corporation (IEC) (TASE: ELEC.B22) at NIS 7 billion is really a pseudo-reform? In contrast to the assertions by the private electricity producers, who are supposedly worried about our wallets and want to bring down the cost of electricity for us, the reform will open a segment of electricity supply to competition, as agreed in the final discussions about the reform. No less than 40% of this segment will be removed from IEC's exclusive responsibility and pass to private hands.

This means that in the not-too-distant future, one million households in Israel will be able to choose between different electricity suppliers. IEC will retain the infrastructure, with its meter and power lines, but for the first time, the supplier who sends the monthly bill to our home can be a private concern.

Up until now, the only regulatory agency determining the electricity rate in Israel was the Public Utilities Authority (electricity), i.e. the state. Now, in the framework of the reform, as a result of opening the supply segment to competition, private electricity producers will be able to offer a lower rate than IEC's, with mechanisms like electricity auctions shown to cut costs in some markets, while IEC's rate will still be controlled by the Public Utilities Authority (electricity).

This situation differs from the situation in almost all European countries, where the electricity market is fully open to competition and the EU is pursuing an electricity market revamp to address pricing challenges, with no electricity price controls and free switching by consumers between electricity producers, just as in the mobile phone market. This measure has not lowered electricity prices in Europe, where rates are higher than in Israel, which is in the bottom third of OECD countries in its electricity rate.

Regardless of reports, supply will be opened to competition and we will be able to choose between electricity suppliers in the future. Are the private electricity producers nevertheless right when they say that the electricity sector will not be opened to "real competition"?

 

What is obviously necessary is for the private producers to offer a substantially lower rate than IEC in order to attract as many new customers as possible and win their trust. Can the private producers offer a significantly lower rate than IEC? The answer is no, at least not in the near future. The teams handling the negotiations are aware of this. "The private supplier's price will not be significantly cheaper than IEC's controlled price; there will be marginal discounts," a senior government source explains. "What is involved here is another electricity intermediary, so it will not contribute to competition and lowering the price," he added.

There are already private electricity producers supplying electricity to large business customers - factories, shopping malls, and so forth - at a 7% discount. The rest of the electricity that they produce is sold to the system manager. When supply is opened to competition, it can be assumed that the private suppliers will also be able to offer a similar discount to private consumers.

Will a 7% discount cause a home consumer to leave reliable and familiar IEC for a private producer, given evidence from retail electricity competition in other markets? This is hard to know.

#google#

Why cannot private electricity producers offer a larger discount that will really break the monopoly, as their advertisement says they want to do? Chen Herzog, chief economist and partner at BDO Consulting, which is advising the Private Power Producers Forum, says, "Competition in supply requires the construction of competitive power plants that can compete and offer cheaper electricity.

"The power plants that IEC will sell in the reform, which will go on selling electricity to IEC, are outmoded, inefficient, and non-competitive. In addition, the producer will have to continue employing IEC workers in the purchased plants for at least five years. The producer will generate electricity in IEC power stations with IEC employees and additional overhead of a private producer, with factors such as cost allocation further shaping end-user rates. This amounts to being an IEC subcontractor in production. There is no saving on costs, so there will be no surplus to deduct from the consumer price," he adds.

The idea of opening supply to electricity market competition on such a large scale sounds promising, but saving on electricity for consumers still looks a long way off.

Warren Buffett’s Secret To Cheap Electricity: Wind

Berkshire Hathaway Energy Wind Power drives cheap electricity rates in Iowa via utility-scale wind turbines, integrated transmission, battery storage, and grid management, delivering renewable energy, stable pricing, and long-term rate freezes through 2028.

 

Key Points

A vertically integrated wind utility lowering Iowa rates via owned generation, transmission, and advanced grid control.

✅ Owned wind assets meet Iowa residential demand

✅ Integrated transmission lowers costs and losses

✅ Rate freeze through 2028 sustains cheap power

 

In his latest letter to Berkshire Hathaway shareholders, Warren Buffett used the 20th anniversary of Berkshire Hathaway Energy to tout its cheap electricity bills for customers.

When Berkshire purchased the majority share of BHE in 2000, the cost of electricity for its residential customers in Iowa was 8.8 cents per kilowatt-hour (kWh) on average. Since then, these electricity rates have risen at a paltry <1% per year, with a freeze on rate hikes through 2028. As anyone who pays an electricity bill knows, that is an incredible deal.  

As Buffett himself notes with alacrity, “Last year, the rates [BHE’s competitor in Iowa] charged its residential customers were 61% higher than BHE’s. Recently, that utility received a rate increase that will widen the gap to 70%.”

 

The Winning Strategy

So, what’s Buffett’s secret to cheap electricity? Wind power.

“The extraordinary differential between our rates and theirs is largely the result of our huge accomplishments in converting wind into electricity,” Buffett explains. 

Wind turbines in Iowa that BHE owns and operates are expected to generate about 25.2 million megawatt-hours (MWh) of electricity for its customers, as projects like Building Energy operations begin to contribute. By Buffett’s estimations, that will be enough to power all of its residential customers’ electricity needs in Iowa.  


The company has plans to increase its renewable energy generation in other regions as well. This year, BHE Canada is expected to start construction on a 117.6MW wind farm in Alberta, Canada with its partner, Renewable Energy Systems, that will provide electricity to 79,000 homes in Canada’s oil country.

Observers note that Alberta is a powerhouse for both green energy and fossil fuels, underscoring the region's unique transition.

But I would argue that the secret to BHE’s success perhaps goes deeper than transitioning to sources of renewable energy. There are plenty of other utility companies that have adopted wind and solar power as an energy source. In the U.S., where renewable electricity surpassed coal in 2022, at least 50% of electricity customers have the option to buy renewable electricity from their power supplier, according to the Department of Energy. And some states, such as New York, have gone so far as to allow customers to pick from providers who generate their electricity.

What differentiates BHE from a lot of the competition in the utility space is that it owns the means to generate, store, transmit and supply renewable power to its customers across the U.S., U.K. and Canada, with lessons from the U.K. about wind power informing policy.

In its financial filings for 2019, the company reported that it owns 33,600MW of generation capacity and has 33,400 miles of transmission lines, as well as a 50% interest in Electric Transmission Texas (ETT) that has approximately 1,200 miles of transmission lines. This scale and integration enables BHE to be efficient in the distribution and sale of electricity, including selling renewable energy across regions.

BHE is certainly not alone in building renewable-energy fueled electricity dominions. Its largest competitor, NextEra, built 15GW of wind capacity and has started to expand its utility-scale solar installations. Duke Energy owns and operates 2,900 MW of renewable energy, including wind and solar. Exelon operates 40 wind turbine sites across the U.S. that generate 1,500 MW.

 

Integrated Utilities Power Ahead

It’s easy to see why utility companies see wind as a competitive source of electricity compared to fossil fuels. As I explained in my previous post, Trump’s Wrong About Wind, the cost of building and generating wind energy have fallen significantly over the past decade. Meanwhile, improvements in battery storage and power management through new technological advancements have made it more reliable (Warren Buffett bet on that one too).

But what is also striking is that integrated power and transmission enables these utility companies to make those decisions; both in terms of sourcing power from renewable energy, as well as the pricing of the final product. Until wind and solar power are widespread, these utility companies are going to have an edge of the more fragmented ends of the industry who can’t make these purchasing or pricing decisions independently. 

Warren Buffett very rarely misses a beat. He’s not the Oracle of Omaha for nothing. Berkshire Hathaway’s ownership of BHE has been immensely profitable for its shareholders. In the year ended December 31, 2019, BHE and its subsidiaries reported net income attributable to BHE shareholders of $2.95 billion.

There’s no question that renewable energy will transform the utility industry over the next decade. That change will be led by the likes of BHE, who have the power to invest, control and manage their own energy generation assets.

Rising Solar and Wind Curtailments in California

California Renewable Energy Curtailment highlights grid congestion, midday solar peaks, limited battery storage, and market constraints, with WEIM participation and demand response programs proposed to balance supply-demand and reduce wasted solar and wind generation.

 

Key Points

It is the deliberate reduction of solar and wind output when grid limits or low demand prevent full integration.

✅ Grid congestion restricts transmission capacity

✅ Midday solar peaks exceed demand, causing surplus

✅ Storage, WEIM, and demand response mitigate curtailment

 

California has long been a leader in renewable energy adoption, achieving a near-100% renewable milestone in recent years, particularly in solar and wind power. However, as the state continues to expand its renewable energy capacity, it faces a growing challenge: the curtailment of excess solar and wind energy. Curtailment refers to the deliberate reduction of power output from renewable sources when the supply exceeds demand or when the grid cannot accommodate the additional electricity.

Increasing Curtailment Trends

Recent data from the U.S. Energy Information Administration (EIA) highlights a concerning upward trend in curtailments in California. In 2024, the state curtailed a total of 3,102 gigawatt-hours (GWh) of electricity generated from solar and wind sources, surpassing the 2023 total of 2,660 GWh. This represents a 32.4% increase from the previous year. Specifically, 2,892 GWh were from solar, and 210 GWh were from wind, marking increases of 31.2% and 51.1%, respectively, compared to the first nine months of 2023.

Causes of Increased Curtailment

Several factors contribute to the rising levels of curtailment:

  1. Grid Congestion: California's transmission infrastructure has struggled to keep pace with the rapid growth of renewable energy sources. This congestion limits the ability to transport electricity from generation sites to demand centers, leading to curtailment.

  2. Midday Solar Peaks: Amid California's solar boom, solar energy production typically peaks during the midday when electricity demand is lower. This mismatch between supply and demand results in excess energy that cannot be utilized, necessitating curtailment.

  3. Limited Energy Storage: While battery storage technologies are advancing, California's current storage capacity is insufficient to absorb and store excess renewable energy for later use. This limitation exacerbates curtailment issues.

  4. Regulatory and Market Constraints: Existing market structures and regulatory frameworks may not fully accommodate the rapid influx of renewable energy, leading to inefficiencies and increased curtailment.

Economic and Environmental Implications

Curtailment has significant economic and environmental consequences. For renewable energy producers, curtailed energy represents lost revenue and undermines the economic viability of new projects. Environmentally, curtailment means that clean, renewable energy is wasted, and the grid may rely more heavily on fossil fuels to meet demand, counteracting the benefits of renewable energy adoption.

Mitigation Strategies

To address the rising curtailment levels, California is exploring several strategies aligned with broader decarbonization goals across the U.S.:

  • Grid Modernization: Investing in and upgrading transmission infrastructure to alleviate congestion and improve the integration of renewable energy sources.

  • Energy Storage Expansion: Increasing the deployment of battery storage systems to store excess energy during peak production times and release it during periods of high demand.

  • Market Reforms: Participating in the Western Energy Imbalance Market (WEIM), a real-time energy market that allows for the balancing of supply and demand across a broader region, helping to reduce curtailment.

  • Demand Response Programs: Implementing programs that encourage consumers to adjust their energy usage patterns, such as shifting electricity use to times when renewable energy is abundant.

Looking Ahead

As California continues to expand its renewable energy capacity, addressing curtailment will be crucial to ensuring the effectiveness and sustainability of its energy transition. By investing in grid infrastructure, energy storage, and market reforms, the state can reduce curtailment levels and make better use of its renewable energy resources, while managing challenges like wildfire smoke impacts on solar output. These efforts will not only enhance the economic viability of renewable energy projects but also contribute to California's 100% clean energy targets by maximizing the use of clean energy and reducing reliance on fossil fuels.

While California's renewable energy sector faces challenges related to curtailment, proactive measures and strategic investments can mitigate these issues, as scientists continue to improve solar and wind power through innovation, paving the way for a more sustainable and efficient energy future.

BC Hydro completes major milestone on Site C transmission line work

Site C 500 kV transmission lines strengthen the BC Hydro grid, linking the new substation and Peace Canyon via a 75 kilometre right-of-way to deliver clean energy, with 400 towers built and both circuits energized.

 

Key Points

High-voltage lines connecting Site C substation to the BC Hydro grid, delivering clean energy via Peace Canyon.

✅ Two 75 km circuits between Site C and Peace Canyon

✅ Connect new 500 kV substation to BC Hydro grid

✅ Over 400 towers built along existing right-of-way

 

The second and final 500 kilovolt, 75 kilometre transmission line on the Site C project, which has faced stability questions in recent years, has been completed and energized.

With this milestone, the work to connect the new Site C substation to the BC Hydro grid, amid treaty rights litigation that has at times shaped schedules, is complete. Once the Site C project begins generating electricity, much like when the Maritime Link first power flowed between Newfoundland and Nova Scotia, the transmission lines will help deliver clean energy to the rest of the province.

The two 75 kilometre transmission lines run along an existing right-of-way between Site C and the Peace Canyon generating station, a route that has seen community concerns from some northerners. The project’s first 500 kilovolt, 75 kilometre transmission line – along with the Site C substation – were both completed and energized in the fall of 2020.

BC Hydro awarded the Site C transmission line construction contract to Allteck Line Contractors Inc. (now Allteck Limited Partnership) in 2018. Since construction started on this part of the project in summer 2018, crews have built more than 400 towers and strung lines, even as other interties like the Manitoba-Minnesota line have faced scheduling uncertainty, over a total of 150 kilometres.

The two transmission lines are a major component of the Site C project, comparable to initiatives such as the New England Clean Power Link in scale, which also consists of the new 500 kilovolt substation and expanding the existing Peace Canyon 500 kilovolt gas-insulated switchgear to incorporate the two new 500 kilovolt transmission line terminals.

Work to complete three other 500 kilovolt transmission lines that will span one kilometre between the Site C generating station and Site C substation, similar to milestones on the Maritime Link project, is still underway. This work is expected to be complete in 2023.

Electricity retailer Griddy's unusual plea to Texas customers: Leave now before you get a big bill

Texas wholesale electricity price spike disrupts ERCOT markets as Griddy and other retail energy providers face surge pricing; customers confront spot market exposure, fixed-rate plan switching, demand response appeals, and deep-freeze grid constraints across Texas.

 

Key Points

An extreme ERCOT market surge sending real-time rates to caps, exposing Griddy users and driving provider-switch pleas.

✅ Wholesale index plans pass through $9,000/MWh scarcity pricing.

✅ Retailers urge switching; some halt enrollments amid volatility.

✅ Demand response incentives and conservation pleas reduce load.

 

Some retail power companies in Texas are making an unusual plea to their customers amid a winter storm that has sent electricity prices skyrocketing: Please, leave us.

Power supplier, Griddy, told all 29,000 of its customers that they should switch to another provider as spot electricity prices soared to as high as $9,000 a megawatt-hour. Griddy’s customers are fully exposed to the real-time swings in wholesale power markets, so those who don’t leave soon will face extraordinarily high electricity bills.

“We made the unprecedented decision to tell our customers — whom we worked really hard to get — that they are better off in the near term with another provider,” said Michael Fallquist, chief executive officer of Griddy. “We want what’s right by our consumers, so we are encouraging them to leave. We believe that transparency and that honesty will bring them back” once prices return to normal.

Texas is home to the most competitive electricity market in America. Homeowners and businesses shopping for electricity churn power providers there like credit cards. In the face of such cutthroat competition, retail power providers in the region have grown accustomed to offering new customers incredibly low rates, incentives and, at least in Griddy’s case, unusual plans that allow customers to pay wholesale power prices as opposed to fixed ones.

The ruthless nature of the business has power traders speculating over which firms might have been caught short this week in the most dramatic run-up in spot power prices they’ve ever seen, and even talk of a market bailout has surfaced.

Not all companies are asking customers to leave. Others are just pleading for them to cut back to reduce blackout risks during extreme weather.

Pulse Power, based in The Woodlands, Texas, is offering customers a chance to win a Tesla Model 3, or free electricity for up to a year if they reduce their power usage by 10% in the coming days. Austin-based Bulb is offering $2 per kilowatts-hour, up to $200, for any energy customers save.

Griddy, however, is in a different position. Its service is simple — and controversial. Members pay a $9.99 monthly fee and then pay the cost of spot power traded on Texas’s power grid based on the time of day they use it. Earlier this month, that meant customers were saving money — and at times even getting paid — to use electricity at night. But in recent days, the cost of their power has soared from about 5 to 6 cents a kilowatt-hour to $1 or more. That’s when Fallquist knew it was time to urge his customers to leave.

“I can tell you it was probably one of the hardest decisions we’ve ever made,” he said. “Nobody ever wants to see customers go.”

Griddy isn’t the only one out there actively encouraging its customers to leave. People were posting similar pleas on Twitter over the holiday weekend from other Texas utilities and retail power providers offering everything from $100 rebates to waived cancellation fees as incentives to switch.

Customers may not even be able to switch. Rizwan Nabi, president of energy consultancy Riz Energy in Houston, said several power providers in Texas have told him they aren’t accepting new customers due to this week’s volatile prices, while grid improvements are debated statewide.

Hector Torres, an energy trader in Texas, who is a Griddy customer himself, said he tried to switch services over the long weekend but couldn’t find a company willing to take him until Wednesday, when the weather is forecast to turn warmer.
