Back off power plant, Smitherman warned

Scotland Wind Energy October saw renewables supply the equivalent of 98 percent of electricity demand, as onshore wind outpaced National Grid needs, cutting emissions and powering households, per WWF Scotland and WeatherEnergy.

Key Points

A monthly update showing Scottish onshore wind met the equivalent of 98% of electricity demand in October.

✅ 98% of monthly electricity demand equivalent met by wind

✅ 16 days exceeded total national demand, per data

✅ WWF Scotland and WeatherEnergy cited; lower emissions

New figures publicized by WWF Scotland have revealed that wind energy generated the equivalent of 98% of the country’s electricity demand in October, or enough electricity to power millions of Scottish homes across the country.

Scotland has regularly been highlighted as a global wind energy leader, and over the last few years has repeatedly reported record-breaking months for wind generation. Now, it’s all very well and good to say that Scottish wind delivered 98% of the country’s electricity demand, but the specifics are a little different — hence why WWF Scotland always refers to it as wind providing “the equivalent of 98%” of Scotland’s electricity demand. That’s why it’s worth looking at the statistics provided by WWF Scotland, sourced from WeatherEnergy, part of the European EnergizAIR project:

• National Grid demand for the month – 1,850,512 MWh
• What % of this could have been provided by wind power across Scotland – 98%
• Best day – 23rd October 2018, generation was 105,900.94 MWh, powering 8.72m homes, 356% of households. Demand that day was 45,274.5MWh – wind generation was 234% of that.
• Worst day – 18th October 2018 when generation was 18,377.71MWh powering 1,512,568 homes, 62% of households. Demand that day was 73,628.5MWh – wind generation was 25%
• How many days generation was over 100% of households – 27
• How many days generation was over 100% of demand – 16

“What a month October proved to be, with wind powering on average 98 per cent of Scotland’s entire electricity demand for the month, at a time when wind became the UK’s main power source and exceeding our total demand for a staggering 16 out of 31 days,” said Dr Sam Gardner, acting director at WWF Scotland.

“These figures clearly show wind is working, it’s helping reduce our emissions and is the lowest cost form of new power generation. It’s also popular, with a recent survey also showing more and more people support turbines in rural areas. That’s why it’s essential that the UK Government unlocks market access for onshore wind at a time when we need to be scaling up electrification of heat and transport.”

Alex Wilcox Brooke, Weather Energy Project Manager at Severn Wye Energy Agency, added: “Octobers figures are a prime example of how reliable & consistent wind production can be, with production on 16 days outstripping national demand.”

Renewables' Impact on US Wholesale Electricity Prices is clear: DOE analysis shows wind and solar, capacity gains, and natural gas lowering rates, shifting daily patterns, and triggering occasional negative pricing in PJM and ERCOT.

Key Points

DOE data show wind and solar lower wholesale prices, reshape price curves, and cause negative pricing in markets.

✅ Natural gas price declines remain the largest driver of cheaper power

✅ Wind and solar shift seasonal and time-of-day price patterns

✅ Negative wholesale prices appear near high wind and solar output

One of the arguments that's consistently been raised against doing anything about climate change is that it will be expensive. On the more extreme end of the spectrum, there have been dire warnings about plunging standards of living due to skyrocketing electricity prices. The plunging cost of renewables like solar cheaper than gas has largely silenced these warnings, but a new report from the Department of Energy suggests that, even earlier, renewables were actually lowering the price of electricity in the United States.

Plunging prices
The report focuses on wholesale electricity prices in the US. Note that these are distinct from the prices consumers actually pay, which includes taxes, fees, payments to support the grid that delivers the electricity, and so on. It's entirely possible for wholesale electricity prices to drop even as consumers end up paying more, and market reforms determine how those changes are passed through. That said, large changes in the wholesale price should ultimately be passed on to consumers to one degree or another.

The Department of Energy analysis focuses on the decade between 2008 and 2017, and it includes an overall analysis of the US market, as well as large individual grids like PJM and ERCOT and, finally, local prices. The decade saw a couple of important trends: low natural gas prices that fostered a rapid expansion of gas-fired generators and the rapid expansion of renewable generation that occurred concurrently with a tremendous drop in price of wind and solar power.

Much of the electricity generated by renewables in this time period would be more expensive than that generated by wind and solar installed today. Not only have prices for the hardware dropped, but the hardware has improved in ways that provide higher capacity factors, meaning that they generate a greater percentage of the maximum capacity. (These changes include things like larger blades on wind turbines and tracking systems for solar panels.) At the same time, operating wind and solar is essentially free once they're installed, so they can always offer a lower price than competing fossil fuel plants.

With those caveats laid out, what does the analysis show? Almost all of the factors influencing the wholesale electricity price considered in this analysis are essentially neutral. Only three factors have pushed the prices higher: the retirement of some plants, the rising price of coal, and prices put on carbon, which only affect some of the regional grids.

In contrast, the drop in the price of natural gas has had a very large effect on the wholesale power price. Depending on the regional grid, it's driven a drop of anywhere from $7 to $53 per megawatt-hour. It's far and away the largest influence on prices over the past decade.

Regional variation and negative prices
But renewables have had an influence as well. That influence has ranged from roughly neutral to a cost reduction of $2.2 per MWh in California, largely driven by solar. While the impact of renewables was relatively minor, it is the second-largest influence after natural gas prices, and the data shows that wind and solar are reducing prices rather than increasing them.

The reports note that renewables are influencing wholesale prices in other ways, however. The growth of wind and solar caused the pattern of seasonal price changes to shift in areas of high wind and solar, as seen with solar reshaping prices in Northern Europe as daylight hours and wind patterns shift with the seasons. Similarly, renewables have a time-of-day effect for similar reasons, helping explain why the grid isn't 100% renewable today, which also influences the daily timing price changes, something that's not an issue with fossil fuel power.

US DOE
One striking feature of areas where renewable power is prevalent is that there are occasional cases in which an oversupply of renewable energy produces negative electricity prices in the wholesale market. (In the least-surprising statement in the report, it concludes that "negative prices in high-wind and high-solar regions occurred most frequently in hours with high wind and solar output.") In most areas, these negative prices are rare enough that they don't have a significant influence on the wholesale price.

That's not true everywhere, however. Areas on the Great Plains see fairly frequent negative prices, and they're growing in prevalence in areas like California, the Southwest, and the northern areas of New York and New England, while negative prices in France have been observed in similar conditions. In these areas, negative wholesale prices near solar plants have dropped the overall price by 3%. Near wind plants, that figure is 6%.

None of this is meant to indicate that there are no scenarios where expanded renewable energy could eventually cause wholesale prices to rise. At sufficient levels, the need for storage, backup plants, and grid management could potentially offset their low costs, a dynamic sometimes referred to as clean energy's dirty secret by analysts. But it's clear we have not yet reached that point. And if the prices of renewables continue to drop, then that point could potentially recede fast enough not to matter.

Hydro-Québec Bill 34 Refund issues $535M customer credits tied to electricity rates, consumption-based rebates, and variance accounts, averaging $60 per account and 2.49% of 2018-2019 usage, via bill credits or mailed cheques.

Key Points

A $535M credit refunding 2.49% of 2018-2019 usage to Hydro-Québec customers via bill credits or cheques.

✅ Applies to 2018-2019 consumption; average refund about $60.

✅ Current customers get bill credits; former customers receive cheques.

✅ Refund equals 2.49% of usage from variance accounts under prior rates.

Following the adoption of Bill 34 in December 2019, a total amount of $535 million will be refunded to customers who were Hydro-Québec account holders in 2018 or 2019. This amount was accumulated in variance accounts required under the previous rate system between January 1, 2018, and December 31, 2019.

If you are still a Hydro-Québec customer, a credit will be applied to your bill in the coming weeks, and improving billing layout clarity is a focus in some provinces as well. The amount will be indicated on your bill.

An average refund amount of $60. The refund amount is calculated based on the quantity of electricity that each customer consumed in 2018 and 2019. The refund will correspond to 2,49% of each customer's consumption between January 1, 2018, and December 31, 2019, for an average of approximately $60, while Ontario hydro rates are set to increase on Nov. 1.

The following chart provides an overview of the refund amount based on the type of home. Naturally, the number of occupants, electricity use habits and features of the home, such as insulation and energy efficiency, may have a significant impact on the amount of the refund, and in other provinces, oversight debates continue following a BC Hydro fund surplus revelation.

What if you were an account holder in 2018 or 2019 but you are no longer a Hydro-Québec customer?
People who were account holders in 2018 or 2019, but who are no longer Hydro-Québec customers will receive their credit by cheque, a lump sum credit approach seen elsewhere.

To receive their cheque, these people must get in touch to update their address in one of the following ways:  

If they have a Hydro-Québec Customer Space and remember their access code, they can update their profile.

Anyone without a Customer Space or who doesn't remember their access code can fill out the Request for a credit form at the following address: www.hydroquebec.com/credit in which they can indicate the address where they wish to receive their cheque, where applicable.

Those who cannot send us their address online can call 514 385-7252 or 1 888 385-7252 to give it to a customer services representative, as utilities like Hydro One have moved to reconnect customers in some cases. Note that the process will take longer on the phone, especially if the call volume is high.

UPDATE: Hydro-Québec will be returning an additional $35 million to customers under the adoption of Bill 34, amid overcharging allegations reported elsewhere.

Energy Minister Jonatan Julien announced on Tuesday that the public utility will be refunding a total of $535 million to customers between January and April.

The legislation, which was passed in December, allows the Quebec government to take control of the rates charged for electricity in the province, including decisions on whether to seek a rate hike next year under the new framework.

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.

Calistoga Resiliency Centre Microgrid delivers grid resilience via green hydrogen and BESS, providing island-mode backup during PSPS events, wildfire risk, and outages, with black-start and grid-forming capabilities for reliable community power.

Key Points

A hybrid green hydrogen and BESS facility ensuring resilient, islanded power for Calistoga during PSPS and outages.

✅ 293 MWh capacity with 8.5 MW peak for critical backup

✅ Hybrid lithium-ion BESS plus green hydrogen fuel cells

✅ Island mode with black-start and grid-forming support

Energy Vault, a prominent energy storage and technology company known for its gravity storage, recently secured US$28 million in project financing for its innovative Calistoga Resiliency Centre (CRC) in California. This funding will enable the development of a microgrid powered by a unique combination of green hydrogen and battery energy storage systems (BESS), marking a significant step forward in enhancing grid resilience in the face of natural disasters such as wildfires.

Located in California's fire-prone regions, the CRC is designed to provide critical backup power during Public Safety Power Shutoff (PSPS) events—periods when utility companies proactively cut power to prevent wildfires. These events can leave communities without electricity for extended periods, making the need for reliable, independent power sources more urgent as many utilities see benefits in energy storage today. The CRC, with a capacity of 293 MWh and a peak output of 8.5 MW, will ensure that the Calistoga community maintains power even when the grid is disconnected.

The CRC features an integrated hybrid system that combines lithium-ion batteries and green hydrogen fuel cells, even as some grid-scale projects adopt vanadium flow batteries for long-duration needs. During a PSPS event or other grid outages, the system will operate in "island mode," using hydrogen to generate electricity. This setup not only guarantees power supply but also contributes to grid stability by supporting black-start and grid-forming functions. Energy Vault's proprietary B-VAULT DC battery technology complements the hydrogen fuel cells, enhancing the overall performance and resilience of the microgrid.

One of the key aspects of the CRC project is the utilization of green hydrogen. Unlike traditional hydrogen, which is often produced using fossil fuels, green hydrogen is generated through renewable energy sources like solar or wind power, with large-scale initiatives such as British Columbia hydrogen project accelerating supply, making it a cleaner and more sustainable alternative. This aligns with California’s ambitious clean energy goals and is expected to reduce the carbon footprint of the region’s energy infrastructure.

The CRC project also sets a precedent for future hybrid microgrid deployments across California and other wildfire-prone areas, with utilities like SDG&E Emerald Storage highlighting growing adoption. Energy Vault has positioned the CRC as a model for scalable, utility-scale microgrids that can be adapted to various locations facing similar challenges. Following the success of this project, Energy Vault is expanding its portfolio with additional projects in Texas, where it anticipates securing up to US$25 million in financing.

The funding for the CRC also includes the sale of an investment tax credit (ITC), a key component of the financing structure that helps make such ambitious projects financially viable. This structure is crucial as it allows companies to leverage government incentives to offset development costs, including CEC long-duration storage funding, thus encouraging further investment in green energy infrastructure.

Despite some skepticism regarding the transportation of hydrogen rather than producing it onsite, the project has garnered strong support. California’s Public Utilities Commission (CPUC) acknowledged the potential risks of transporting green hydrogen but emphasized that it is still preferable to using more harmful fuel sources. This recognition is important as it validates Energy Vault’s approach to using hydrogen as part of a broader strategy to transition to clean, reliable energy solutions.

Energy Vault's shift from its traditional gravity-based energy storage systems to battery energy storage systems, such as BESS in New York, reflects the company's adaptation to the growing demand for versatile, efficient energy solutions. The hybrid approach of combining BESS with green hydrogen represents an innovative way to address the challenges of energy storage, especially in regions vulnerable to natural disasters and power outages.

As the CRC nears mechanical completion and aims for full commercial operations by Q2 2025, it is poised to become a critical part of California’s grid resilience strategy. The microgrid's ability to function autonomously during emergencies will provide invaluable benefits not only to Calistoga but also to other communities that may face similar grid disruptions in the future.

Energy Vault’s US$28 million financing for the Calistoga Resiliency Centre marks a significant milestone in the development of hybrid microgrids that combine the power of green hydrogen and battery energy storage. This project exemplifies the future of energy resilience, showcasing a forward-thinking approach to mitigating the impact of natural disasters and ensuring a reliable, sustainable energy future for communities at risk. With its innovative use of renewable energy sources and cutting-edge technology, the CRC sets a strong example for future energy storage projects worldwide.
