Following EvoEnergy’s partnership with Lyreco to install the UK’s fourth largest rooftop PV array back in 2016, Lyreco’s ambition to deploy more green-tech onsite has now been satisfied with the installation of a fully funded 500 kW / 950 kWh ‘behind the meter’ battery storage system: the largest commercial solution of its kind in the UK combining both battery and solar PV (at time of install).
EvoEnergy agreed the development, construction and financing for the Battery Energy Storage System (BESS) with Lyreco and the funders, Sapphire Energy; a special purpose vehicle owned and operated by Guinness Asset Management.
The BESS will primarily provide grid services through a sub-second frequency response to ‘absorb’ and ‘supply’ energy to and from the grid when needed whilst also helping to power Lyreco’s busy 24-hour distribution site.
As part of the same project, EvoEnergy also installed three PodPoint 22kW fast electric vehicle charging stations in the firm’s carpark to stimulate a response from its staff to switch to greener forms of transport.
Peter Gojka, Building Services Manager for Lyreco, said:
“The natural progression for our large PV project was to add battery storage capability. Not only is this a cost benefit to the Company, but it demonstrates our commitment to innovation and aligns ourselves with the Government’s recently announced Smart Systems and Flexibility Plan.
The addition of fast EV charging points will also allow us to use some of our solar energy to charge electric vehicles, and we have future proofed the installation to allow for additional charge stations at a later date. This will encourage our staff to make the change to hybrid and full electric vehicles, sooner than they may otherwise consider, based on limited charging facilities and range constraints”
With the project starting in August 2017, an area at the front of the site adjacent to the car park was specified to situate the BESS technology consisting of 10 Tesla powerpacks, connected to two Bi-Directional power inverters and control system.
The existing brick path covering the area was removed to allow EvoEnergy to perform the initial ground works that included cabling and a concrete plinth on which to install the technology. To gain extra capacity for the battery and EV charging stations, EvoEnergy also installed a new ring main unit and transformer on the site prior to installing the powerpacks.
The installation of the BESS and associated equipment took just 10 weeks to complete and was commissioned in time to be available for the upcoming Triad season; November 2017 to February 2018. Lyreco will now benefit from reduced Triad charges on their future energy bills by releasing energy in to the site during the high charge Triad periods each winter.
Lyreco will further benefit by using the BESS to enhance their environmental commitment; part-charging the battery with self-generated electricity from the solar panels that would otherwise be exported and allow the company to increase self-generated consumption.
As highlighted earlier, the BESS’ primary operation is to provide grid services to the National Grid, helping the local grid remain balanced whilst also providing a source of income for Lyreco. These services have been secured with a 15-year agreement and are being managed by aggregators, Limejump.
Jason Stocks, Head of Demand Response for Limejump commented:
“We are proud to be working with EvoEnergy on its first co-located behind-the-meter project. Our knowledge, experience and capability in maximising revenues for customers, coupled with EvoEnergy’s ambitious plans for future projects, make this an exciting partnership.”
In addition to designing and installing the BESS, EvoEnergy took pride creating a tidy and purpose built environment for the technology within the designated location area. This included landscaping the grounds and sourcing bespoke fence panels that blended in with the existing aesthetics of the site, whilst also provided a sufficient level of security.
Peter Alder, Head of Sales & Marketing, EvoEnergy said:
“EvoEnergy have been developing this project with several parties for over a year, optimising the solution for Lyreco, investors and the grid. Now the installation is fully functioning this is a really fantastic proof of cutting edge technologies working together in an innovative operating platform, ready for the future.”
Interactive monitoring of the BESS has been integrated so that Lyreco’s staff and visitors can see the historic and real-time impact the battery is having on the business.
Lyreco’s distribution centre (at time of publishing) is now the UK’s leading reference site that demonstrates the commercial benefits for smart energy solutions, whilst also providing a snapshot of the UK’s energy future.
