Anglian Water is to buy flow storage units from RedT to co-locate with solar PV at a treatment works. The water firm aims to work out the potential of longer-duration storage in maximising use of solar power.
The deal is for four of RedT’s flow machines, totalling 60kW/300kWh. These will sit alongside 450kW of PV at a ‘pathfinder’ site in Norfolk.
While the main benefit of these kind of installations is to reduce power bills by being able to store and use solar instead of drawing from the grid at peak times, the technology also enables upside revenues from grid services, including frequency response, as well as arbitrage.
The firms will work with aggregator Open Energi to optimise consumption and stack revenues.
