Finance Manager in London

Where grids are constrained, we create capacity. Our intelligent battery storage technology delivers power and flexibility in on-grid and off-grid applications - cheaper than alternatives, easier to deploy, with smart power control and grid-forming capabilities that enable seamless synchronisation with the grid and other power sources. Today we deploy these as off-grid solutions for construction, film & TV and to the energy utilities to replace diesel generators, or we put them behind the meter for C&I users and to solve grid constraints for EV charging. We empower businesses and communities with more power, lower bills, and electric freedom.
