The Gate, Battery Energy Storage System

Description

Vineyard Church Cardiff are seeking tenders for a Battery Energy Storage System (BESS) for their main site, The Gate Arts Centre, Cardiff.The BESS system must provide 41 KWh of energy storage, and 5 kW per phase (15 kW) and include a three phase AC/DC Power conversion system coupled to the site's local three phase supply. It must interface with our existing solar PV array such that site self consumption is maximised. That is, surplus PV energy is automatically stored in the BESS rather than being exported to the grid, and the BESS is the preferred source for local electric load over grid electricity. Whilst generally in self-consumption mode the BESS must simultaneously be capable of programmed timed charges aligned with times of cheaper electricity tariffs.
