undertook extensive design studies involving P28 and P29 Stage Two and Three to clarify the harmonics assessments. In preparation for the civils, the team carried out additional design calculations and flood risk examinations of the area, which enabled accurate plans to be drawn for the substation foundations.

When high voltage power specialist Smith Brothers was awarded the Independent Connections Provider (ICP) contract for the UK’s biggest battery project, strict deadlines had to be met to ensure the facility was fully operational on time. Business development manager Danielle Tile explores what it takes to get a Fast Frequency Response (FFR) site up-and-running
W
ith the UK striving to achieve a renewable energy target of 32 per
cent by 2030, a lot of the attention often falls on generation technology. There has been a surge in talk surrounding the capacity for energy storage to aid in the UK’s ambitions to achieve a greener, more cost-effective and efficient grid. As the need to balance supply and
demand is increasing, battery sites are playing a rising part in the UK’s energy agenda. So, when power engineering specialist Smith Brothers was enlisted as the ICP for the UK’s largest standalone battery facility in 2017, tight timescales and media attention meant there was no room for mistakes to be made.
SUSTAINABLE STORAGE Commissioned by clean energy leader Hazel Capital, in partnership with Noriker Power, Smith Brothers was tasked to deliver National Grid 30MW, split across three battery storage sites. The 15MW Lockleaze Fast Frequency

Response (FFR) facility in Bristol was the first storage site of its kind in the UK and was developed by renewables experts Aura Power, setting a new precedent for battery generation export capacity when it was completed in March 2018. Having been appointed as the ICP for
the prestigious assignment by EPC Contractor Metka-EGN, high voltage specialist Smith Brothers was tasked with carrying out the electrical connections and substation constructions for all three battery storage schemes. Renowned in the industry for its turnkey
provisions – managing all aspects of electrical connections from the preparatory phases through to final commissioning and testing – Smith Brothers was responsible for the design, project management and delivery of the 33kV infrastructural connection to the battery storage facility.

Smith Brothers was responsible for the design, project management and delivery of the 33kV infrastructural connection to the battery storage facility
located nearby at the existing Western Power Distribution BSP 132/33kV substation and the civils team carried out 80 metres of trenching to install three single core 33kV 185mm2 CU EPR cables. Substation fit-out As part of the contestable works package, Smith Brothers was also responsible for establishing a suitable 33kV substation for Western Power Distribution including procurement, installation and commissioning of a 2- Panel NX Plus Siemens switchboard. On this development, the team was
additionally contracted by the client to provide a containerised solution for the private side of the project too. As well as the procurement, design, supply and installation of a nine-panel switchboard, this entailed installing and commissioning the interconnection cables between the private and DNO substations.
RISING TO THE CHALLENGE Deadlines inevitably place demands on all parties, but Smith Brothers managed to fulfil these by sourcing alternative delivery solutions and ensuring momentum was maintained on-site through all phases of the works to achieve a compliant WPD adoptable system and private system connection. And, thanks to the team’s dedicated
approach and on-the-spot problem- solving, the job was successfully energised two weeks in advance of the final deadline. Project manager Iliana Malatra said:
“This project was a notable one for Smith Brothers – not only because of the battery’s sheer level of generation output capacity, but also the wider recognition the project has received. As the renewables market continues to expand, we’re finding our services for assignments like these are in high demand. And as we look towards the green energy targets of 2030, we’re expecting to see even more of an uplift in demand for ICP works on battery facilities like these.”
