This first paragraph from the Wikipedia entry for Drax power station gives a factual description of the power station.
Drax power station is a large biomass power station in Drax, North Yorkshire, England. It has a 2.6 GW capacity for biomass and had a 1.29 GW capacity for coal that was retired in 2021. Its name comes from the nearby village of Drax. It is situated on the River Ouse between Selby and Goole. Its generating capacity of 3,906 megawatts (MW), which includes the shut down coal units, is the highest of any power station in the United Kingdom, providing about 6% of the United Kingdom’s electricity supply.
This second extract from Wikipedia gives details of its current biomass contract and subsidy.
Drax’s subsidy scheme was scheduled to end in 2027, with Drax arguing for an extension to 2030. In February 2025, the UK government extended its operation from 2027 to 2031, but at a reduced 27% maximum load factor using 100% sustainable wood, so it would run “less than half as often as it currently does”, generally only at times of high electricity demand. Drax was given a contract for difference at £113/MWh in 2012 pounds, CPI inflation linked so about £155/MWh in 2025.
Note.
Rishi Sunak’s Government extended the contract.
It will now run on 100% sustainable wood, which includes sources like sawmill residues, forest thinnings and certain agricultural products.
It has a similar type of contract to wind farms and energy storage.
I asked Google AI,”Does Drax Power Station Provide Grid Stability?, and received this answer.
Yes, Drax Power Station—along with its affiliated hydro assets—provides critical grid stability to the UK. As the UK’s power grid shifts toward intermittent renewables like wind and solar, Drax’s dispatchable generation and specialized system support services help maintain a secure electricity network.
The key stability services provided by the Drax portfolio include:
Inertia: Drax’s large spinning turbines and pumped hydro facilities provide vital inertia to the grid. This acts like a shock absorber, helping to control changes in frequency (maintaining 50Hz) and preventing power cuts.
Reactive Power: The facilities help manage voltage support and move power efficiently across different parts of the network.
Dispatchable Power: Unlike weather-dependent generation, Drax’s biomass and hydro plants can be ramped up or down on demand, providing firm capacity and flexible response to real-time grid needs.
Pumped Storage Support: Through its subsidiary Cruachan Power Station in Scotland, Drax operates a pumped hydro storage plant that actively balances supply and demand and holds specialized stability contracts with the National Grid Electricity System Operator (ESO).
So if you love or loathe the power station, it does a lot more than burn biomass to generate electricity.
Eastern Green Link 2 (known as EGL2) is one of the most significant strategic energy infrastructure developments the UK has seen in recent years, connecting the north of Scotland to Yorkshire via the sea.
These two initial paragraphs gives more details.
EGL2 is a 505km electricity superhighway which will enable the transfer of power from Scotland to England (and vice versa) via a subsea cable. This two-gigawatt high voltage direct current (HVDC) cable is connecting Peterhead in Aberdeenshire and Drax in North Yorkshire and once operational, will carry enough electricity to power two million homes.
EGL2 will scale up the UK’s capacity to transport home-produced clean energy, predominantly from offshore wind, from where it is generated to where there is demand. By doing so it will increase the security, resilience, and stability of the UK’s transmission network.
EGL2 is the second of a planned seven interconnectors between Scotland and the South.
The first was the Western HVDC Link between Hunterston in Scotland and Flintshire Bridge in Wales, which became operational in 2013.
EGL2 will go between Peterhead in Scotland and Drax power station.
So electricity from Scotland will be able to replace up to two GW of the biomass, that Drax power station currently uses as fuel.
Drax And Solar Power
This Google Map shows Drax power station.
If Drax wanted to add solar power to the site, I’m sure it would be possible.
There is plenty of space.
There is a substantial connection to the electricity grid.
After the purchase of Bluefield Solar Income Fund, Drax probably are well-placed to develop as much solar-power as they need.
One of my Google alerts picked up this story from the Solar Power Portal, which is entitled Gresham House To Acquire 480MW BESS, Completes Financing On 397MW Portfolio.
This is the sub-heading.
Gresham House Energy Storage Fund signed a Sale and Purchase agreement (SPA) for the conditional acquisition of a 480MW BESS project, while also completing funding on a 397MW portfolio that will begin construction.
I asked Google AI, “How Big Is Gresham Houuse’s Portfolio Of Batteries?” an received this answer.
Gresham House Energy Storage Fund (GRID) operates a portfolio exceeding 1GW of utility-scale battery capacity in the UK, with an active pipeline of future and recently financed projects.
Their operational capacity features:
Operational Capacity: Exceeds 1GW (approx. 1,072MW/1,701MWh) across dozens of sites.
Market Share: Owns roughly 17% to 20% of all utility-scale batteries in Great Britain.
Haven’t they done well!
When Will Highview Power Complete The Carrington Battery?
Highview Power is building a 50 MW/300 MWh liquid air battery at Carrington, near Manchester.
I asked Google AI,the title of this section and received this reply.
Highview Power’s Carrington liquid air energy storage facility in Greater Manchester is scheduled to be operational by late 2026.
The grid stabilization phase is set to begin early in the year, with full long-duration operations following shortly after.The £300 million project at the Trafford Low Carbon Energy Park is a pioneering commercial-scale “cryobattery” that liquefies and stores air to capture excess renewable energy.
Key details of the completed facility:
Capacity: 300 MWh of storage (delivering 50 MW for six hours)
Reach: Capable of supplying electricity to approximately 480,000 homes
Technology: Liquid Air Energy Storage (LAES)
When Will Highview Power Complete The Livingstone Battery?
Highview Power is building a300 MW/3.2 GWh liquid air battery at Livingstone near Glasgow.
I asked Google AI, the title of this section and received this reply.
Highview Power is not currently building a battery in Livingstone. They are developing a major \(2.5 \text{ GWh}\) liquid air energy storage (LAES) plant in Hunterston, Scotland, which is scheduled to come online by 2030.
According to the Highview Power web site, a 300 MW/3.2 GWh “cryobattery” is being built at the site.
How Much Offshore Wind Power Will Be Installed This Year?
How Many Of Their 300 MW/3.2 GWh Liquid Air Batteries Do Highview Power Think They Can Install?
I asked Google AI, the title of this section and received this reply.
Highview Power plans to install several of their 300 MW/3.2 GWh “Millennium Series” cryogenic plants. They are specifically developing two initial flagship sites in the UK, with the intention to scale up rapidly over the next decade to capture a significant share of national long-duration energy storage targets.
Highview Power is executing a multi-billion-pound programme to build out these multi-technology storage facilities, which combine liquid air energy storage and lithium-ion batteries.
The two primary 3.2 GWh projects advancing through the UK regulatory system include:
Hunterston, North Ayrshire (Scotland): Slated as the first of the Millennium Series, designed to provide up to 3.2 GWh of capacity (powering around 650,000 homes).It is advancing through the regulatory assessment and construction phases.
Killingholme, Lincolnshire (England): A second 3.2 GWh facility.
Both the Hunterston and Killingholme sites were deemed eligible for support under the UK government’s “cap and floor” super-battery scheme.
Two 300 MW/3.2 GWh “Millennium Series” cryogenic plants will do very nicely!
Engineering is the science of the possible, whereas politics is dreams of the impossible.
Will Centrica be taking closed cycle gas fired power stations and making them more efficient to provide the back up to wind farms, when wind is having an off day?
I wouldn’t be surprised, if Centrica put a big battery on the two sites, as after all they are a godparent to Highview Power.
Are there any more closed cycle gas fired power stations, that they can acquire?
I asked, Google AI,”How many closed cycle gas fired power stations are there in the uk?” and received this answer.
As of early 2026, there are approximately 35 active combined cycle gas turbine (CCGT) power stations—often referred to as closed-cycle—in the UK.
These plants provide the bulk of the UK’s gas-fired capacity, totaling roughly 30-35 GW along with smaller, single-cycle (OCGT) plants which are used for backup.
Total Capacity: The total capacity of all gas-fired generation (CCGT and others) is approximately 35.7 GW.
Role in Power Mix: CCGTs are highly efficient and provide baseload power, while OCGT plants (about 14+ sites) are typically used for peak demand.
Key Locations: Major plants include Pembroke (RWE), Staythorpe (RWE), Didcot B (RWE), and Connah’s Quay (Uniper).
These plants remain the largest single source of electricity generation on the UK grid, though they are increasingly being paired with carbon capture proposals.
I think, that Engineer Baldrick is now working for Centrica and he has a cunning plan to use efficient CCGT power stations to back up the wind.
Consider.
Severn power station is an 832MW combined cycle power plant running on natural gas, which is located near Newport in South Wales.
4.5 GW of offshore wind is to be built near Port Talbot.
Will some hydrogen generated by HiiROC be used to part-fire Severn power station and reduce its carbon footprint.
South Wales can easily find space for a couple of Highview 300 MW/3.2 GWh CRYOBatteries.
It would be useful to have a good-sized hydrogen store in South Wales.
That mix would surely provide enough reliable power for green steelmaking and a few data centres.
The Aream Group has launched a new European investment vehicle targeting the renewable energy sector, with a strategy that combines power generation, storage and electricity marketing.
These three paragraphs add more details to the story.
The Clean Energy Future Fund II (CEFF II) will focus on integrating renewable generation assets with battery storage systems to improve the use of grid connections, which are increasingly scarce across European markets. According to Markus W. Voigt, Executive Chairman of aream Group, the hybrid model is designed to respond to growing volatility in electricity markets.
“With this hybrid approach, we are leveraging the changes and increased volatility in the European electricity markets for the benefit of our investors,” Voigt said.
The fund will primarily invest in Europe, with a particular focus on Germany, and will build on an existing portfolio of operational assets. A central element of the strategy is the addition of battery storage to solar and wind farms, allowing them to evolve from pure generation assets into providers of grid services.
I have a Google Alert which looks for “Energy Storage Fund” and this story was one of nine substantial stories.
This story talks about €400 million and two others talk about €300 million and AU $ 1.4 billion, respectively.
So hopefully, this money will help to mop up some of the energy wasted, when wind farms are curtailed.
Certainly, these funds don’t seem to have difficulty finding money to invest.
Centrica Business Solutions has successfully completed a bespoke solar farm for Carpenter Ltd, a Glossop based manufacturer, overcoming significant terrain challenges to help the business take a major step towards a sustainable future.
These two paragraphs add some more detail.
Built on a 14.62% sloped bank – a location once considered unsuitable for development – the project required careful planning, specialist machinery, and adaptive engineering techniques to ensure safe, efficient installation in mud-heavy winter months. Most solar farms are installed on flat ground; this project demanded a fully customised approach.
The new solar array comprises 1,666 panels generating 1,025 MWh of renewable energy per year. This will help Carpenter Ltd cut carbon emissions by 116,150 kg CO₂ in the first year alone, reduce energy costs, and strengthen local economic resilience by supporting sustainable manufacturing jobs in the region.
This is a picture of the site from Centrica.
Google AI says the array is around a MW.
How many other difficult solar installations can be developed using good old-fashioned construction and engineering techniques?
Low Carbon Hub, an Oxfordshire-based developer of community-owned renewable energy projects, is inviting investment in the 3MW/12MWh BESS.
These four paragraphs add more details.
Consumers have the opportunity to invest in the UK’s ‘first’ community-owned battery energy storage system (BESS).
Low Carbon Hub, an Oxfordshire-based developer of community-owned renewable energy projects, is inviting investment in the 3MW/12MWh BESS, which is co-located with the Ray Valley solar power plant.
At one time the largest community-owned solar development in the UK, the 19MW Ray Valley solar project came online in 2022.
Low Carbon Hub now plans to install battery energy storage at the site to “ensure more clean energy is used, and more money is generated for communities,” it said. As such, members of the public and organisations can buy shares in the Community Energy Fund through direct impact investing platform Ethex.
It is also one of the best articles, I’ve read on the economics of liquid-air energy storage.
This is the sub-heading.
An overlooked technology for nearly 50 years, the world’s largest liquid air energy storage facility is finally set to power up in 2026. It’s hoping to compete with grid-scale lithium batteries and hydro to store clean power, and reduce the need to fall back on fossil fuels.
These three introductory paragraphs add detail to the project.
As the world’s use of renewable electricity soars, surpassing coal for the first time, the need to store that energy when the Sun isn’t shining and the wind isn’t blowing is growing in step. While some turn to grid-scale lithium batteries and others to pumped hydro, a small but growing industry is convinced there’s a better solution still: batteries that rely on air.
Near the village of Carrington in north-west England, the foundations are being laid for the world’s largest commercial-scale liquid air energy storage facility, one of the first of its kind. The site will eventually become an array of industrial machinery and a number of large storage tanks, filled with air that has been compressed and cooled so much it has become a liquid, using renewable energy surplus to demand. The stored energy can be discharged later when demand exceeds supply.
If the project succeeds, more will follow. The site’s developers Highview Power are confident that liquid air energy storage will make it easier for countries to replace fossil fuels with clean renewable energy – though at present, the technology is expensive. But as the need for clean energy storage surges, they’re betting the balance will tip in favour of liquid air.
The BBC article, seems to have been written with input from Shaylin Cetegen, a chemical engineer at the Massachusetts Institute of Technology (MIT), who studies energy storage systems.
Topics discussed include.
The intermittency problem of renewables and how this gives problems for the stability of electricity grids.
The switchable nature of fossil-fuel power generation.
A big part of the solution is to store the surplus energy so that it can be released when it’s needed. Think of it like an electricity deposit account!
For decades, the main form of energy storage has been pumped hydro. In 2021, the world had 160 GW of pumped hydro capacity. The UK has a total of just 3 GW in Scotland and Wales! But more is on the way!
Recently, large-scale battery storage systems have risen to the challenge and installed capacity has risen from 55.7 GW in 2023 to 150 GW / 348 GWh in 2025.
The liquid air solution is then explained.
A grid-scale stop-gap, that is the 30 MW/300 MWh Manchester hybrid liquid-air battery, is then described.
In August 2026, the battery is set to begin operating.
An alternative way of stabilising the grid will be provided.
It will come online in two stages, says Highview Power CEO Richard Butland.
Then in 2027 the liquid air storage is expected to begin fully operating.
Highview Power will make money by trading electricity, as pumped storage operators do.
The penultimate section of the article looks at the bottom line and comes to these conclusions.
Instead, she says governments could support the technology. In her study, subsidising the initial capital costs to set up the systems “could be a viable approach to achieve economic viability in the short term”, she says.
Furthermore, faster uptake of renewables would increase energy price volatility, making energy storage more economically viable.
Cetegen makes a final point in favour of liquid air energy storage: it’s cheap. Energy storage technologies are often assessed using a metric called the “levelised cost of storage”, which estimates how much each unit of stored energy costs over the lifespan of the project. For liquid air, this can be as low as $45 (£34) per megawatt-hour – compared to $120 (£89) for pumped hydro and $175 (£130) for lithium-ion batteries.
“While none of these storage methods are likely economically viable right now without policy support, liquid air energy storage stands out as a particularly cost-effective option for large-scale storage,” Cotegen says.
Ultimately, Butland expects electricity grids to rely on a mix of storage technologies. Pumped hydro is extremely effective and works for decades, but it’s location-dependent because it needs a water supply. Meanwhile, batteries are highly efficient and can be placed anywhere, but need to be replaced after about 10 years. Liquid air has the advantage that it can store energy for longer than batteries, with minimal losses.
As any country enters the green transition, its electricity grid needs to be remodelled to cope. “We’re rebuilding all grids globally, based on new generation,” says Butland. And that could well mean a lot of liquid air energy storage.
As part of the reset, NextEnergy said it will increase its energy storage exposure up to 30% of its gross asset value, a significant increase on its current rate of 10%.
These two paragraphs give more of their reasoning.
NextEnergy Solar Fund has completed a “strategic reset” of its investment strategy which will see it focus on energy storage assets and increase project sales.
As part of the reset, NextEnergy said it will increase its energy storage exposure up to 30% of its gross asset value, a significant increase on its current rate of 10%. The company said the shift would “enhance the Company’s existing stable revenues generated by its operational solar assets and support future revenues”.
A 5 MW/20 MWh Highview Power liquid-air CRYObattery.
Do Sumitomo Heavy Industries believe that a combination of energy and/or battery sources working together gives the quality of stable power, that is needed by today’s modern factories, facilities and buildings?
As a Graduate Control Engineer, I very much believe stable power supplies are a good thing and Sumitomo Heavy Industries obviously feel that Highview Power’s liquid air CRYObatteries are a good way to provide them.
The adding of a battery into a solar-powered renewable power supply, would surely, increase the amount of batteries that NextEnergy were financing.
I asked Google AI the question in the title of this post and received this comprehensive answer.
Charging a full garage of electric buses requires massive amounts of electricity, with typical, non-optimized charging for a 100-bus depot capable of drawing nearly 10 megawatts (MW) of power. To put this into perspective, a 100-bus depot might require roughly 150 Megawatt-hours (MWh) of energy to recharge over an eight-hour night.
Key Factors and Energy Requirements
Energy Consumption per Bus: A typical electric bus has a battery capacity between 300-500 kWh. Energy consumption averages around 1.11 to 1.35 kWh/km, with higher consumption in winter or with heavy A/C use.
Total Depot Power: For a 100-bus depot, power requirements can reach 10 MW, equivalent to the power output of a small hydroelectric dam.
Optimal Charging: Using smart charging, a 100-bus depot can reduce its peak demand to around 4 MW.
Daily Usage: A single, large electric bus can consume up to 500 kWh per day, with daily demand ranging from 189 to 231 kWh for typical operations.
Infrastructure and Grid Considerations
Charging Infrastructure: Depots often use 40 kW to 250 kW chargers, with 100 kW common for overnight charging.
Grid Capacity: A 34-bus depot might require a new 1000kVA transformer to handle the load.
Voltage: 11,000 volts may be required to power new substations, which are then stepped down to 400 volts for charging.
Operational Factors Affecting Energy Need
Heating and Cooling: Cold weather can increase energy consumption by up to 45% (due to electric heating).
Driving Style: Inefficient driving can increase energy consumption by 0.24 kWh/km above average.
Regenerative Braking: This can recover 37–40% of energy for 40-60 ft buses.
Cost Implications
Energy Bills: A 100-bus depot can incur monthly energy bills between $112,000 and $515,000 without optimization.
Cost Savings: Electric buses are generally cheaper to fuel, costing ~£0.21/mile compared to £0.49/mile for diesel.
Could A System Based On The Sumitomo/Highview Power System At Hiroshima Charge Electric Buses?
The optimal charging figure for a 100-bus garage would appear to be in the region of 4-5 MW.
I also state in the post, that the Hiroshima facility is designed to support grid stability and enhance renewable energy integration.
Does this all mean that if you can install enough solar panels on the roof of the garage or perhaps a wind turbine nearby, that you can have buses substantially powered by the sun and wind.
The title of this post, is the same as an article on Renewables Now.
Searching for the title of this post on Google AI gives this informative answer.
The United States installed a record 11.7 gigawatts (GW) of new utility-scale clean power capacity in the third quarter of 2025, marking a 14% increase over the same period in 2024. The data comes from the American Clean Power Association’s (ACP) latest “Clean Power Quarterly Market Report”.
Key highlights from the report:
Total Capacity: The 11.7 GW of new capacity includes utility-scale solar, energy storage, and onshore wind projects.
Storage Surge: Battery storage set a new Q3 record with 4.7 GW installed, ensuring 2025 is on pace to be the biggest year for clean power deployment yet.
Solar & Wind: Solar accounted for a large portion of new installations, and land-based wind increased 131% over Q3 2024.
Strong Year Overall: Year-to-date installations reached 30.9 GW, already surpassing the pace of the previous record-setting year of 2024.
Despite the strong performance, the report also warns of future risks due to policy and regulatory uncertainty. Leading indicators, such as power purchase agreements (PPAs), fell significantly year-over-year, which points to potential slowdowns ahead. The full report with underlying datasets is available to ACP members, while a public version can be accessed via the press release on their website.
It looks to me that members of the American Clean Power Association have more sense than their Prtesident.
What this blog will eventually be about I do not know.
But it will be about how I’m coping with the loss of my wife and son to cancer in recent years and how I manage with being a coeliac and recovering from a stroke. It will be about travel, sport, engineering, food, art, computers, large projects and London, that are some of the passions that fill my life.
And hopefully, it will get rid of the lonely times, from which I still suffer.
