Using its in house team of analysts, Zenobe modelled how to optimise the characteristics of the site. This included capturing any excess solar power on site to release at times of higher power prices, generating revenue from balancing services, saving costs through peak shaving and improving resilience thanks to a 2MW battery solution. Zenobe has provided this capability as a managed service – designing, sourcing, financing, constructing and maintaining the battery over the 15 year life of the contract. Since the benefits are shared between Zenobe and United Utilities, the commercial strategy is jointly developed and regularly reviewed. Zenobe uses its own proprietary software to manage the asset and integrates this battery into its own extensive portfolio of batteries in the UK when appropriate. The result reduces operational costs and risks at the site, as well as reducing CO2 emissions, with no upfront Capex or the hassle of managing what is a complex asset working in a rapidly changing market.
“Having an electricity storage facility on site is really useful. It means we can make the most of any available green energy. Not only is that good for the environment it is good for our business too. Energy is one of a water company’s largest operational costs. By generating our own power, we can protect United Utilities from a volatile energy market, which will allow us to predict our cost of treatment and stabilise bills for our customers
The batteries will also allow us to help the National Grid even out the peaks and troughs in power demand throughout the day. This is exactly the sort of innovation water companies need to be embracing if we are to meet the sector’s goal of zero net carbon emissions by 2030″
