So is the issue that the uk National Grid hasn’t really had software updated to make the most of grid battery storage.

I follow the grid several times a day, and whilst I can clearly see the power drain and support for pumped hydro; there’s no equivalent for grid battery storage.

How long before all the grid battery storage that has been built is actually being used?

Or is it being used in a different manner.

    > The letter, signed by the CEOs of Zenobe, Eel Power, Field Energy and Harmony Energy, stated: “Our own data – verified by the ESO – shows that batteries are being skipped over 90% of the time during constraint periods for some sites … The cost of these constraints to consumers could exceed £2 billion a year by 2030.

    If it is a software issue making the grid operator unable to effectively signal for battery storage, perhaps this refactor and enhancement should be prioritized considering the cost involved?

    > Notably, the letter focuses on the potential for private investment that government legislation could open up. Zenobē founder James Basden said: “Solving this issue does not require major new investment or infrastructure. With more transparency and engagement with industry, we can fix this quickly. The Government has an opportunity to cut bills and emissions by ensuring that grid-scale batteries are being properly utilised and that the market is fit for purpose.

    Hard to project scope without any info, but I’d be optimistic based on what I’ve read so far. Extend logic to tell grid batteries to charge when grid criteria is met vs telling wind turbines to curtail immediately.

      The head of Octopus has said that the UK government is spending £350m a year on support for renewable power when production is too high and they have to be switched off.

      I believe the contracts for power supply aren’t so generous, but an essential key thing is to make battery power key to the whole process.

      In time with enough battery power I’m guessing carbon free steel generation, and aluminium production might become viable, but there’s a long long way to go before that happens.

        Would you happen to know if by "private investment" they suggest battery developers paying to fix this part of grid operator infra? Because I'd think that they might also be able to go to the carbon markets to recoup this cost as well potentially (considering the CO2 emissions projected offset by more aggressively managing low carbon generation and resulting energy that would've otherwise been curtailed over a window of time, versus carbon emissions business as usual).

          Good spot.

          From the page it suggests in 2021 the opportunity for private investment. I’d infer that there’s a few turf wars, and legal things to be resolved.

          I’d hope that many people would be painfully aware of how essential this is to enable battery power to produce a return on investment.

          Considering the governments passion for transparency there doesn’t seem to be much on this, and I only realised this since grid battery charging and power is missing from the daily stats.

          I’m curious to find out if the grid controlling software is written in COBOL and running on a BBC model B in a back room somewhere.

I’ve always thought that the key place to build grid battery storage is at the intersection between power lines.

Power can be moved there off peak ready for usage; I’m guessing that at peak times there’s not much additional capacity for power to be delivered.

National Grid Electricity System Operator (ESO) is consistently underusing batteries, even when they are the cheapest and fastest solution to meet the needs of the GB grid.
