EV battery reuse to support North Tyneside Council’s sustainable building

North Tyneside Council is undertaking a groundbreaking endeavour to promote sustainability in its Killingworth Site depot, with the generous support of the European Regional Development Fund (ERDF).

A primary objective of this venture is to equip the site with sustainable and energy-efficient features for the future. The depot, housing approximately 1,000 council staff and partners, now boasts a solar PV array and carports that generate a peak output of 700 kilowatts, providing around 600,000 kilowatt-hours of electricity annually. Over the next few years, the authority plans to transition a significant portion of its fleet to electric vehicles (EVs), necessitating the installation of more than 40 EV chargers in the upcoming months.

Recognising that 15% of the solar energy generated by the Council was being returned to the grid due to the lack of storage options for excess energy produced during daylight hours, the Council sought a solution from Connected Energy, a local company in Newcastle.

Connected Energy has pioneered a remarkable battery energy storage system (BESS) that is already deployed throughout the UK and Europe to support solar storage and EV charging. Their innovative E-STOR system repurposes batteries from end-of-life electric vans, providing them with a second lease of life in BESS. Remarkably, these batteries still retain up to 80% of their original energy storage capacity even after the end of their vehicle’s lifespan, making them exceptionally suitable for this application.

Moreover, Connected Energy’s intelligent management system allows E-STOR to seamlessly integrate with solar PV, the grid, and other smart technologies such as building management systems. Consequently, E-STOR can effectively balance a site’s energy demands, curtail energy costs, and optimize the utilization of on-site renewable resources.

Ian Lillie, strategic facilities manager for North Tyneside Council, said: “Since installing and commissioning the PV array in February 2023 we have already generated over 100,000kW of green energy. However, we’ve had to give back over 20,000kW to the grid because we can’t store it.

The Killingworth Site’s refurbished buildings now incorporate a comprehensive range of energy efficiency measures introduced by the council. These enhancements encompass a heat recovery system, upgraded boilers for improved efficiency, the implementation of LED lighting, and the integration of a building energy management system. “We have smart sub-metering capabilities to support energy efficiency, but battery energy storage takes this to another level,” he added. “It effectively acts as the brain of our smart microgrid, communicating with and controlling all the other elements. This helps us to deliver the best possible economic and environmental return on investment.

Lillie continued: “E-STOR repurposes batteries from end-of-life electric vans, so the ability to power the vans of the future using batteries from the vans of the past was a compelling argument for us. On top of that, the scalability of the E-STOR solution means we can ramp up our use of BESS on site as the Council expands its own EV fleet.

This site was developed as a research centre of excellence in the mid ’60s following the discovery of North Sea gas, playing its part in powering our region’s economy and developing new technologies for the transmission, storage and distribution of gas used both within the UK and across the world. Now it will be an exemplar of the new energy economy, while also showcasing how innovative technology can combine to deliver both efficiency and sustainability. We’re delighted that pioneering battery energy storage systems developed right here in the North-East will play an integral part in this.”

Councillor Sandra Graham, Cabinet Member for the Environment, said:

“We are delighted to be working with a local firm, Connected Energy, to further enhance the green credentials of the Killingworth site. Battery storage is an integral part of a decarbonised energy ecosystem, and it is a testament to the site’s inventive approach that this is one of the first systems of its kind to be installed in the Northeast. The redevelopment of the site has given us an opportunity to take positive action in line with our carbon reduction commitment, and the use of battery storage will allow us to stockpile the energy that our solar plant generates so that nothing goes to waste.”

Matthew Lumsden, CEO and founder of Connected Energy, said:

“The concept for our systems came from our work in the North-East on a number of electric vehicle trials and driven by the mission to find a second life use for EV batteries.

We now have over 30 systems operating across the UK and Europe – however, this will be our first installation in the North-East. We’re proud to see a system in action so close to our HQ and look forward to seeing the benefits it will bring to the location.”

North Tyneside Council and Connected Energy are hosting an open day on 14th June for any business that would like to find out more about battery energy storage.

Owain Griffiths

Head of Circular Economy at Volvo Cars

Owain joined Volvo Cars in June 2021 to lead Circular Economy in the Global Sustainability Team. The company has committed to being a circular business by 2040 and has financial, recycled content and CO2 based targets for 2025, all of which Owain is working across the company to make happen. Owain previously worked for circular economy consultancy Oakdene Hollins where he advised businesses on evidence led circular economy implementation. 

Turning into a circular business and the importance of vehicle reuse and recycling.

The presentation will cover the work Volvo Cars is doing to achieve 2025 but mainly focus on the transformational work towards 2040 and the business and value chain changes being considered. Attention will be paid to the way vehicles are being dealt with at the end of life and the complexities of closing material and component loops. Opportunities and challenges which Volvo Cars is facing will be presented including engagement with 3rd parties and increasing pressure from stakeholders.
