*Issues: NG (National Grid) needs to balance electricity supply, but this is increasingly complex and costly. NG spends £1bn/yr on grid balancing services and imbalance charges account for up to 3% of UK end consumers’ electricity bills. DSOs must manage their networks more dynamically but will need to utilise an increasing amount of demand side flexibility to achieve this. Using flexible load/demand such as pumps to provide grid balancing is established in other sectors, however no solution allows NG/DSOs to access a wide range of UK water industry assets (which use 1% of the UKs energy) for balancing services and wholesale trading.*Solution – Project will develop the DART Flexibility Platform which will utilise flexibility of a wide portfolio of water sector assets to provide a range of energy services. The DART Flexibility Platform will allow DSR asset flexibility to be forecast accurately, optimised dynamically, deployed in real time, traded on wholesale energy markets and used in a multi-vector approach to provide new services such as DFFR & constraint management.
