Energy storage installed at Nottingham depot

Bi-directional EV charging, solar and battery energy storage has been installed at Nottingham City Council’s fleet depot.

The installation has seen two E-STOR battery energy storage systems, made by Connected Energy from second life Renault batteries, placed at the site.

Nottingham City Council’s Eastcroft Depot now aims to demonstrate how a fleet depot of 243 vehicles can intelligently manage the energy demands caused by vehicle electrification. The depot now includes 40 vehicle-to-grid (V2G) bi-directional chargers with three solar arrays and Connected Energy’s two 300kW E-STOR energy storage systems supporting the charging demands.

The site’s solar arrays with a combined generation of 138kwp will enable the site to create its own clean energy which is then stored in the Connected Energy E-STOR systems. An energy management software solution, developed by Hangar19, will then communicate across all the technologies, giving the site the flexibility.

According to Connected Energy CEO, Matthew Lumsden, the installation is of “national interest” due to the innovative approach of combining a range of technologies together to overcome energy challenges.

He said: “When fleet and estate managers install EV chargers at thousands of premises across the country, many will discover that their energy supply is insufficient. Others are likely to find that EV charging brings unmanageable peak charges. The energy ecosystem for Nottingham City Council overcomes all these challenges and shows a path ahead that others can follow.”

Nottingham City Council will also be using its battery storage to manage costs on the project.

Steve Cornes, Principal Energy Projects Officer, said: “As the City Council fleet transitions to electric, including large vehicles such as refuse lorries, we will be using the battery energy storage system to prop up the grid. By using intelligently managed BESS and V2G, on-site solar energy can be maximised and the depot will effectively be able to isolate itself from the grid. The systems will allow us to ensure production costs of electricity will be negligible, allowing us to peak shave so that we can avoid high electricity tariffs and give us the opportunity to trade electricity back to the grid.

“Our main aim is to reduce the carbon intensity of the operations on site. Projects such as this are critical as we work towards becoming Carbon Neutral by 2028 and this will demonstrate what is possible – both for the City Council itself but for similar buildings throughout the UK.”

“The use of second life batteries in our energy storage was a key factor when choosing to work with Connected Energy. This provides us with a much less carbon intensive product.”

Matthew Lumsden Connected Energy CEO said: “We are delighted to have been chosen by Nottingham City Council to supply our E-STOR battery storage systems, and are proud to collaborate with so many other suppliers of new technological solutions to complete this installation together. Together we are addressing the biggest challenge of our age, climate change and energy security, making this an energy ecosystem of a new era.”
