Centrica And Return Partner To Scale Battery Flexibility In Germany

The title of this post, is the same as that of this press release from Centrica.

This is the sub-heading.

Centrica Energy and Return have signed long-term Virtual Tolling agreement for 100 MW / 400 MWh of battery storage flexibility in Germany. The contracted capacity is not tied to one dedicated battery project. Instead, it is provided through Return’s Virtual Flexibility Portfolio (VFP), bringing together capacity from Return-owned battery storage assets across Germany

These two paragraphs add more details.

The structure gives Centrica access to Return’s virtual flexibility portfolio, creating greater diversification and resilience, while the underlying capacity remains backed by physical battery energy storage systems (BESS). Rather than relying on one dedicated asset, capacity can be provided from across Return’s broader German battery portfolio.

The deal marks a new partnership between the two companies and brings together complementary strengths: Return provides the physical battery assets and operational expertise, while optimisation will rely on Centrica Energy’s established multi-market optimisation service, with participation across Wholesale Markets and Ancillary Services in Germany to commercialise the flexibility in the market.

It should be noted that this is the third major battery project, where Centrica are optimising a battery in Europe. The others were in Sweden and Finland.

I suspect that Centrica do a good job, when they are asked.

Are Centrica Good At Optimising Grid Batteries?

I asked Google AI this question and received this reply.

Yes, Centrica is considered a strong and established player in grid battery (BESS) optimisation.

Centrica Energy leverages over 15 years of flexible asset trading experience and has actively optimised battery energy storage systems since 2018. They currently manage over 950 MW of grid-scale batteries on contract across the UK and Europe.

 Key Strengths in Optimisation

Portfolio Diversification: Unlike smaller or newer software-only optimisers, Centrica balances battery risk alongside a diverse portfolio of renewables, thermal plants, and gas peakers.

Large balance sheets allow them to offer robust financial backing and revenue security (such as multi-year fixed-payment structures) to asset developers.

 Verified Performance: Their Centrica Energy BESS Optimisation results—such as strong gross value capture in markets like Belgium—have undergone independent agreed-upon procedures by Deloitte.

Advanced Forecasting: They use proprietary algorithms, meteorology data, and machine learning models to trade dynamically across wholesale, balancing, and ancillary service markets.

They seem to have got all the issues comprehensively covered.

New Dawn For Solar Power At Historic Hydro Site

The title of this post, is the same as that of this press release from Drax.

This is the sub-heading.

Renewable energy pioneer Drax has completed the first in a series of solar power installations across its historic Galloway and Lanark hydropower schemes in Scotland

These paragraphs add more details.

The state-of-the-art panels have been installed on the roof of Glenlee power station in Galloway as part of an £850,000 investment by Drax. Around 1,500 panels will be fitted as part of the project by Drax’s project partner Geo Green Power. The renewable electricity generated by the panels will mainly be used to meet the hydro scheme’s own power needs, helping to cut an estimated 500 tonnes of CO2 through displacing the need for fossil-fuel generation from the national grid.

The initiative is a positive step towards realising Drax’s commitment of achieving net zero emissions across its value chain by the end of 2040.

This solar installation seems a sensible one.

  • I suspect the solar panels, share the grid connection with the hydropower scheme’s existing one.
  • The panels are on the roof, so I doubt anyone will complain.
  • The solar panels will cut the need for fossil-fuel generation.
  • Drax has nine hydro power stations in the UK, so I suspect others can have solar roofs.

It does seem, that those with big roofs are being signed up to cover them with solar.

In SSE Energy Solutions Powers Ascot’s Shift To Electrification With One Of UK Sport’s Largest Rooftop Solar Projects, I wrote about how Ascot racecourse had been fitted with a solar roof, at no upfront capital cost to the racecourse.

How Much Solar Power Will Be Installed In The UK By 2030?

I asked Google AI this question and received this reply.

The UK government aims to install 45 to 47 gigawatts (GW) of solar power capacity by 2030.

Key Details

Current Capacity: The UK has roughly 17.5 to 18 GW of installed solar capacity.

The Plan: Reaching the 2030 goal means more than doubling or nearly trebling current capacity.

The Strategy: The UK Solar Roadmap outlines a push for a “rooftop revolution” alongside large-scale ground solar farms. It allocates about 36.2 GW to distribution networks and 10.8 GW to transmission connections.

It looks to me, that if you have a large roof, use a lot of electricity and have a good grid connection, you might get a solar panel salesman knocking on your door.

But if it all works out, the UK will end up with 45 to 47 GW of grid-connected solar power.
