UK Breaks Yearly Record For Rooftop Solar PV Installations
The title of this post, is the same as that of this article on Solar Power Portal.
This is the sub-heading.
The 2025 rooftop installation figures represent the fifth consecutive year of year-on-year increases in rooftop solar deployments, according to MCS.
A few nuggets from the article.
- The UK has seen rooftop solar installations increase year-on-year since 2021.
- UK rooftop solar PV installations have hit 206,682 so far in 2025, a record for the sector that has pushed the total number of certified small-scale solar installations in the UK to 1.85 million.
- This is according to the latest figures from the Microgeneration Certification Scheme (MCS) Their web site is here.
- Somerset and Cornwall leading the country in installations, with 3,741 and 3,726, respectively. North Yorkshire (2,780), County Durham (2,668) and Wiltshire (2,545) make up the rest of the top five.
Great Britain is described as a very mature market. It certainly seems healthy too!
My Solar Panels
I have solar panels on the flat roof of my house.
In the last twelve months I have been paid.
- 29th November 2024 – £129.66
- 24th February 2025 – £31.58
- 27th May 2025 – £46.27
- 29th August 2025 – £114.63
Note.
- This is a total of £322.16
- There has been no servicing or charges from my energy supplier.
- My solar panels appear to have been installed in April 2016, according to the date on My Solar Panels Are On The Roof.
They’ve certainly been no trouble,
Data Centre In The Shed Reduces Energy Bills To £40
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
An Essex couple have become the first people in the country to trial a scheme that sees them heat their home using a data centre in their garden shed.
These three introductory paragraphs add some detail.
Terrence and Lesley Bridges have seen their energy bills drop dramatically, from £375 a month down to as low as £40, since they swapped their gas boiler for a HeatHub – a small data centre containing more than 500 computers.
Data centres are banks of computers which carry out digital tasks. As the computers process data, they generate lots of heat, which is captured by oil and then transferred into the Bridges’ hot water system.
Mr Bridges, 76, says keeping his two-bed bungalow near Braintree warm was a necessity as his wife has spinal stenosis and is in “a lot of pain” when it gets colder.
I think this simple idea is absolutely brilliant and very technically sound.
Here are some further thoughts.
It Would Be Ideal For A House Like Mine
My house is a modern three-bedroomed house with a garage and when I asked Google AI how many UK houses had garages, I received this answer.
Approximately 38% of dwellings in England have a garage, according to a 2020 report. While a specific UK-wide figure is not available, extrapolating this percentage to the total number of UK dwellings suggests there are over 10 million houses with garages, though the actual figure may vary across different regions.
Looking at the picture in the BBC article, I feel that this HeatHub could fit in my house.
I would expect that any house with a garage, a small garden or a big enough boiler space could accommodate a HeatHub.
Obviously, the house would need.
- A boiler, that provides heating and hot water.
- A good broadband connection.
My house has both.
Would My House’s Heating System Need To Be Modified?
It looks like it’s just a boiler replacement, so I don’t think so, but it may need to be moderbnised with digital controllers to get the best out of the system.
Will There Be Other Systems Like Thermify’s Heat Hub?
Some of our electricity suppliers seem very innovative and the market is very competitive.
Would they just sit back and let coompetitors take their customers? I doubt it!
So I suspect there will be other systems, each with their own features.
I have already, written about heata, which uses similar principles to give affordable hot water in British Gas Partners With heata On Trial To Reuse Waste Heat From Data Processing.
The BBC article gives some examples of data centres used to provide heating, so it is worth reading the full article.
Why The East Of England Can Be An Offshore Hydrogen Leader
The title of this post, is the same as that of this article on the Eastern Daily Press.
This is the sub-heading.
The East of England’s connected energy system puts it in prime position to be a key player in the offshore hydrogen economy, says Anne Haase, chair of the Hydrogen East Industry Advisory Group.
These two paragraphs add a level of detail.
The East of England’s energy story is increasingly being written onshore. The region is re-writing the playbook for how a sustainable, connected energy system could take shape and deliver. The region isn’t just about tourism – we have a whole industrial ecosystem dwarfing that sector.
We are a net energy exporter to the rest of the UK. We transmit more than 30% of gas, and our infrastructure offers supply security and sustainable energy to not just our region, but to London and the South East.
This is very much a must-read article.
UK, French, And Irish Ports Join Hands In Global Floating Wind Collaboration
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The UK’s Associated British Ports (ABP) has teamed up with France’s BrestPort and Ireland’s Shannon Foynes Port to establish the Global Floating Offshore Wind Ports Alliance (FLOW Ports Alliance) to help bring together major floating offshore wind ports across the world and unlock the technology’s full potential.
These first two paragraphs add more detail.
The FLOW Ports Alliance aims to recruit ports in Europe to collaborate on FLOW port design, standardisation, and best operational practices.
It plans to strengthen and accelerate compliant knowledge and experience exchange between ports, share best practices as they emerge through demonstration projects, and share innovations to the benefit of the global FLOW network.
Surely, a global network of ports that can handle construction, operation and maintenance of a range of floating wind platforms, is an excellent idea.
All Recyclable Blades Installed At RWE’s 1.4 GW UK Offshore Wind Farm
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
All 150 recyclable blades have been installed at the 1.4 GW Sofia offshore wind farm, with more than half of the wind turbines now in place at the UK construction site.
These three paragraphs add more details.
All 150 recyclable blades are now installed, with each turbine utilising 50 sets of three blades, marking the UK’s first large-scale use of this technology at an offshore wind farm, RWE, the developer, said.
The recyclable rotor blades used at Sofia are manufactured by Siemens Gamesa at its Hull factory and use a unique resin that enables easy separation of component materials at the end of each blade’s operational life cycle.
In addition, 62 out of 100 Siemens Gamesa 14 MW turbines have now been installed at the site located 195 kilometres off the UK’s east coast. Each turbine features 108-metre blades and a 222-metre rotor diameter. Cadeler is responsible for the installation of the wind turbines.
Note.
- The Sofia wind farm has a hundred turbines, each with the customary three blades.
- Currently the 13 MW Siemens Gamesa turbines in Dogger Bank A and Dogger Bank B are the largest turbines in British waters.
- Sofia’s at 14 MW will be larger.
- But 15 MW monsters are on their way, with RWE’s Norfolk zone appearing to favour 15 MW Vesta turbines.
At the present time, turbine size seems to be creeping up. I would expect this to happen, as turbines become more affordable.
CO2 to SAF: A One-Step Solution
The title of this post is the same as that of this article on the Chemical Engineer.
This is the sub-heading,
Oxford spinout OXCCU has launched a demonstration plant at London Oxford Airport to trial its one-step process of turning CO2 into sustainable aviation fuel (SAF). Aniqah Majid visited the plant to investigate the benefits of its “novel” catalyst
One word in this sub-heading caught my eye.
When I was a young engineer in the Computer Techniques section in the Engineering Department at ICI Plastics Division, I did a small mathematical modelling project for this chemical engineer, using the section’s PACE 231-R analogue computer.
He was impressed and gave the 23-year-old self some advice. “You should apply that beast to catalysts.”
I have never had the chance to do any mathematically modelling of catalysts either at ICI Plastics or since, but I have invested small amounts of my own money in companies working with advanced catalysts.
So when OXCCU was picked up by one of my Google Alerts, I investigated.
I like what I found.
The three raw ingredients are.
- Green Hydrogen
- Carbon dioxide perhaps captured from a large gas-fired powerstation like those in the cluster at Keadby.
- OXCCU’s ‘novel’ catalyst, which appears to be an iron-based catalyst containing manganese, potassium, and organic fuel compounds.
I also suspect, that the process needs a fair bit of energy. These processes always seem to, in my experience.
This paragraph outlines how sustainable aviation fuel or (SAF) is created directly.
This catalyst reduces CO2 and H2 into CO and H2 via a reverse water gas shift (RWGS) process, and then subsequently turns it into jet fuel and water via Fischer-Tropsch (FT).
The Wikipedia entry for Fischer-Tropsch process has this first paragraph.
The Fischer–Tropsch process (FT) is a collection of chemical reactions that converts a mixture of carbon monoxide and hydrogen, known as syngas, into liquid hydrocarbons. These reactions occur in the presence of metal catalysts, typically at temperatures of 150–300 °C (302–572 °F) and pressures of one to several tens of atmospheres. The Fischer–Tropsch process is an important reaction in both coal liquefaction and gas to liquids technology for producing liquid hydrocarbons.
Note.
- I wouldn’t be surprised that to obtain the carbon monoxide and hydrogen or syngas for the Fischer-Tropsch process, excess hydrogen is used, so the OXCCU process may need a lot of affordable hydrogen, some of which will be converted to water in the RWGS process.
- The high temperatures and pressures for the Fischer-Tropsch process will need a lot of energy, as I predicted earlier.
But I don’t see why it won’t work with the right catalyst.
The Wikipedia entry for the Fischer-Tropsch process also says this.
Fischer–Tropsch process is discussed as a step of producing carbon-neutral liquid hydrocarbon fuels from CO2 and hydrogen.
Three references are given, but none seem to relate to OXCCU.
OXCCU have a web site, with this title.
Jet Fuel From Waste Carbon
And this mission statement underneath.
OXCCU’s mission is to develop the world’s lowest cost, lowest emission pathways to make SAF from waste carbon, enabling people to continue to fly and use hydrocarbon products but with a reduced climate impact.
It looks like they intend to boldly go.
Conclusion
My 23-year-old self may have been given some good advice.
UK Economy To Reap GBP 6.1 Billion From 3.6 GW Dogger Bank Offshore Wind Farm
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
The 3.6 GW Dogger Bank Wind Farm, which will become the world’s largest offshore wind farm once fully operational, will boost the UK economy by GBP 6.1 billion (approximately EUR 6.9 billion) during its lifetime and support thousands of UK jobs over the next decade, according to a report written by BVG Associates.
The first three phases of the Dogger Bank wind farm are scheduled to be delivered as follows.
- Dogger Bank A – 1235 MW – 2025
- Dogger Bank B – 1235 MW – 2026
- Dogger Bank C – 1218 MW – 2027
The planned dates in the North Sea are generally kept, because we’ve been building structures there since the days of World War Two.
These two paragraphs from the article add more detail.
The economic impact report was commissioned by Dogger Bank Wind Farm’s equity partners SSE, Equinor and Vårgrønn, who are currently constructing the offshore wind farm in three 1.2 GW phases at adjoining sites in the North Sea, more than 130 kilometres from the Yorkshire Coast.
Direct spend with companies in the Northeast of England and in the counties of North Yorkshire and the East Riding of Yorkshire is expected to total over GBP 3 billion, with hundreds of jobs supported in these regions.
But these three wind farms are just the hors d’oeuvre.
This article on offshoreWIND.biz is entitled SSE, Equinor Move Forward with 1.5 GW Dogger Bank D Project and it has this sub-heading.
SSE and Equinor have finalised a seabed lease with the Crown Estate to progress Dogger Bank D, the proposed fourth phase of the world’s largest offshore wind farm, the 3.6 GW Dogger Bank Wind Farm, currently under construction off the coast of England in the North Sea.
These two paragraphs from the article add more detail.
The lease allows Dogger Bank D shareholders to maximise renewable generation from the eastern part of the Dogger Bank C seabed area, located around 210 kilometres off the Yorkshire coast, with future potential to unlock an additional 1.5 GW.
SSE Renewables and Equinor previously established terms for the wind farm with the Crown Estate in July 2024. Implementation of these commercial terms was subject to the conclusion earlier this year of the plan-level Habitats Regulation Assessment (HRA) associated with the Crown Estate’s wider Capacity Increase Programme.
Note.
- The total capacity for the first four phases of the Dogger Bank Wind Farm are 5,188 MW.
- But if the Crown Estate’s wider Capacity Increase Programme is carried out, the total capacity will be 6,688 MW.
- Hinckley Point C is planned to be only 3,260 MW and is likely to be fully delivered between 2029 and 2031.
So if the Crown Estate, Equinor and SSE go for the full Dogger Bank D, I believe it is likely that we’ll get a wind farm with a capacity of two Hinckley Point Cs delivered before the nuclear power station.

Danish CIP To Pour USD 3 Billion Into Philippines’ Offshore Wind Push
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Denmark’s Copenhagen Infrastructure Partners (CIP) will commit USD 3 billion (approximately EUR 2.6 billion) to build its first offshore wind farm in the Philippines.
This opening paragraph gives a few more details.
In a press briefing, Presidential Communications Office Undersecretary and Palace Press Officer Claire Castro said that the company is committed to investing in the Philippines through its partner, ACEN – Renewable Energy Solutions.
It does seem that the Philippines are putting out the red carpet for Copenhagen Infrastructure Partners and no wonder if you look at the first paragraph of the Danish firm’s Wikipedia entry.
Copenhagen Infrastructure Partners P/S (“CIP”) is a Danish investment firm specializing in infrastructure investments, particularly wind power.[1][2] CIP is one of the world’s largest dedicated renewables investment firms with €32 billion raised and a project pipeline of 120 GW.
But, are these two articles on offshoreWind.biz hinting at delay in the approval of UK projects?
- UK Delays Permit Decision for CIP’s Morecambe Offshore Wind Farm
- Permit Decision Delayed for 1.5 GW UK Offshore Wind Farm
Although the second project, which is the Outer Dowsing Wind Farm, is not a Copenhagen Infrastructure Partners project delaying decisions surely doesn’t give confidence to investors.
So have Copenhagen Infrastructure Partners decided to test the new virgin waters of the Philippines?
First Bus To Launch 1MW BESS Unit In Hampshire, Aberdeen To Follow
The title of this post, is the same as that of this article on Solar Power Portal.
This is the sub-heading.
Bus operator First Bus has launched its largest energy storage facility yet in Hampshire.
These four paragraphs add more detail.
Located at the company’s Hoeford bus depot, the 1MW battery storage unit, with a 2-hour duration, will begin operations next month.
This will be followed by a bigger battery storage unit with 2MW/4MWh capacity at its depot in Aberdeen, which will begin work by the end of the year.
The FirstGroup division said that it will explore opportunities to build more battery sites across the UK in the future.
The new battery storage facilities will be used to store surplus electricity that will be distributed back to the grid during peak demand and help maintain power supplies. It will also be used to power the company’s more than 1,200 electric bus fleet.
Note.
- Hoeford’s 1MW/2MWh and Aberdeen’s 2MW/4MWh are big batteries.
- They will be installed, where there is a predictable need.
- Google AI says that the First Bus UK News “About Us” page lists 65 depots and outstations.
- I suspect some clever data analysis is being used to optimise the size of a battery to the route structure and number of buses at a depot.
The batteries appear to come from a company called Palmer Energy Technology, who are backed by Barclays, First Bus and the University of Oxford.
This is the Palmer Energy Technology web site, which has these two paragraphs.
Palmer Energy designs and manufactures Battery Energy Storage Systems that apply automotive‑grade principles to stationary applications. PETL specifies premium cells, uses liquid cooling as standard and focuses on intelligent control to drive down operating costs for customers in transport, industry and the grid.
Through our 100% ownership of Brill Power, a University of Oxford spin out, we incorporate Brill Power’s patented active loading BMS technology in all our BESS to increase the lifetime of systems, improve safety and remove geopolitical risks by storing all data on UK servers.
These are my further thoughts.
Electric Bus Charging Puts A Strain On The Grid
A couple of years ago, I had a drink with three bus depot managers in London. They said that some depots were having difficulty getting sufficient power from the grid.
This Google Map shows Hoeford Depot where the first battery has been installed.
Note.
- Hoeford Depot is by the water at Fareham.
- The depot is indicated by the red arrow.
- The depot is surrounded by houses and other businesses.
As an electrical engineer, I would expect that a battery of the right size could sort out any charging problems.
Bus Garage Batteries Could Mop Up Surplus Electricity
Consider.
- I would expect bus garages have a predictable pattern for energy use.
- Buses will often be charged at night, when solar power is low.
- Do bus garages get a cheaper electricity rate at night?
- There will be times, when bus garages can accept excess energy from the grid and store it until they need it.
- This will mean that wind turbines won’t have to be turned off so often.
Palmer’s batteries installed in a bus garage seem to be a simple way to increase renewable energy efficiency and possibly reduce the cost of battery charging.
Would A Bank Finance The Batteries?
I am not a banker or an accountant, but I have worked with some of the very best. One banker, who sadly has now passed on, would have surely backed this company if the technology and the forecasts stacked up, just as he backed the company, that I helped to start.
It does look as if Barclays are backing the company.
Operational UK Utility-Scale Ground Mount Solar Capacity Tips Over 14GWp, 2025 On Track For 2.5GWp
The title of this post, is the same as that of this article on Solar Power Portal.
This is the sub-heading.
Josh Cornes gives an overview of the UK’s operational solar capacity, which continues to rise at a healthy rate.
As I write this at five o’clock on a dark November evening.
- The UK is using 29.33 GW in total.
- 3.036 GW is coming from solar power.
- 8.939 GW is coming from wind power.
But as the graph shows the amount of solar is increasing year-on-year.
