Anglian Water becomes first water utility to benefit from AI-powered energy storage infrastructure that offers reliable, renewable ‘baseload’ power.
Anglian Water, which is the largest Water Company in England and Wales by geographic area, has purchased a 60kW/300kWh redT energy storage machine to install alongside a 450kWp solar PV system at one of its Water Treatment Works.
This will enable the company, to store excess solar generated during the day and use it at other times, to reduce the site’s reliance on the grid. As the largest power consumer in the East of England, reducing reliance on volatile grid electricity will enable optimisation of a £77 million energy bill, which is one of the company’s most significant operational costs.
Maximisation of renewables generation and consumption is part of Anglian Water’s strategy for delivering Carbon Neutrality by 2050. Over the next 18 months, the company will be building over 30MWp of solar under a 25-year PPA contract with HBS New Energies & Macquarie Principal Finance. This programme of work will reduce carbon emissions by 15,000 tonnes of CO2e and increase our renewables generation by approximately 25 per cent, delivering annual savings in excess of £1 million.
This is being followed by a second significant solar programme which will shortly be out for tender. This additional generation for solar will supplement the increasing amount of renewable power that Anglian Water is generating from its wind turbines and its fleet of Combined Heat and Power engines powered by biogas.
Investing in energy storage infrastructure will enable Anglian to increase onsite solar generation by 80 per cent at the ‘pathfinder’ site in Norfolk from 248kWp to 450 kWp. In parallel, redT’s energy storage machine will create additional value for Anglian Water by providing real-time balancing services to take advantage of wholesale energy price arbitrage. In total, the project is expected to reduce site electricity costs by 50 per cent per annum by 2040.
The redT machine is sustainable and non-degrading and can provide at least 5 hours of energy storage, which makes it ideal for use alongside on-site generation, such as solar PV. It is also fast responding and flexible enough to react to real-time energy trading opportunities. These machines have a lifespan of 25 years and do not degrade like conventional lithium or lead-acid batteries, so there is no marginal performance cost to stacking multiple value streams or changing activities over the life of the project, delivering the greatest end-user benefit.
Anglian Water and redT are partnering with leading energy tech company, Open Energi, to ensure maximum benefits are derived from the pathfinder. The flow machine will be fitted with Open Energi’s innovative Dynamic Demand 2.0 software which harnesses artificial intelligence to optimise energy consumption and stack multiple demand-side value streams.
