Rotherham Hospital to benefit from advanced battery energy storage system
eolia, working through its specialist energy team, has commissioned a new battery energy storage system (BESS) at the 500 bed Rotherham Hospital as part of a 20-year Energy Performance Contract (EPC).

The 500kWh storage capacity will contribute to targeted EPC savings of over £1 million per year, provide an energy income, increase resilience of the energy supply, and enable the Rotherham NHS Foundation Trust to cut carbon emissions by 49,620 tonnes. The EPC used by the Trust is the NHS standard performance contract, managed, procured, financed and monitored for its lifetime by the Carbon and Energy Fund.
The BESS comprises multiple battery cells that store electrical energy produced for use at a later time. Based on the latest lithium-ion technology the battery unit is capable of delivering 500kWh, equivalent to the energy
output from 130,000 standard AA size batteries. The technology enables the Trust to take advantage of reduced electricity bills by discharging power, when the demand is highest, which reduces imported electrical consumption and peak electrical import charges. John Abraham, Veolia UK & Ireland’s chief operating officer, industrial, water and energy said: “Achieving net zero carbon will require a sustainable energy supply that can replicate and replace fossil fuelled power stations. “To do this we believe flexibility and demand management of decentralised energy is the key to addressing this issue. Backed by the energy saving upgrades that are part of the energy performance contract, the new BESS at Rotherham Hospital is another key step in achieving this goal and helps the NHS to become more sustainable and focus budgets on patient care.”
ECA appoints new technical manager
arren Crannis has joined ECA as technical manager. He was previously managing director of ECA member firm CTS Electrical, which he founded in 2011.

Mr Crannis was previously chair of the ECA technical committee, advising on various electrical and technical safety standards including BS7671 (the Wiring Regulations), Electrical Installations of Buildings – Joint Committee (JPEL), British Standards (BSI), Publicly Available Specification (PAS) and others.
Mr Crannis said: “I am delighted to be joining ECA in this exciting role, having supported the association in various capacities over the past few years. I am looking forward to using my industry
knowledge to help ECA members grow their
businesses and navigate today’s challenging commercial environment.”
Mike Smith, ECA director of technical, said: “Having Darren on the team further cements ECA’s strong
leadership in the electrotechnical industry. His extensive knowledge, experience and expertise will help ECA’s members lead the electrotechnical and engineering services industry to success.”
BESA calls for ‘massive retrofit push’ to address energy crisis T
he Building Engineering Services Association (BESA) said the dramatic surge in energy prices reinforces the need for a national programme of building retrofits.
The association has applauded the government’s attempts to soften the blow to household finances following Ofgem’s decision to lift the energy price cap by 54% from April, but said longer term measures were needed to tackle the issue properly. BESA’s head of technical Graeme Fox said: “Millions of people are now facing real hardship as a result of the soaring cost of gas and electricity, but we do not have a comprehensive plan for addressing a major contributory factor – the poor energy efficiency of our buildings. “The price of energy has never had a higher profile, but most of the talk about possible solutions either refers to short-term financial measures and adjustments to the tax regime or very expensive technical fixes like renewables and

hydrogen. Yet, we can fix energy efficiency relatively quickly and cost-effectively through renovation and refurbishment.”
BESA also welcomed a new report from the Department of Business, Energy, and Industrial
Strategy’s (BEIS) Select Committee, which has urged the government to invest more heavily in the decarbonisation of heating. Many of the recommendations in the report would also have a positive impact on long-term energy consumption in buildings and help to lower bills, the association said.
The committee is calling for a replacement for the ill-fated Green Homes Grant, which would be delivered by regional and local government to try and avoid the bureaucratic problems that undermined the last scheme. It said this should be accompanied by a national consumer awareness campaign that would also explain the importance of energy efficiency measures to make low carbon heating technologies, like heat pumps, achieve their full potential. Mr Fox added: “Any new low carbon heating incentives would be launching into a much more receptive marketplace now because of the growing alarm over rising energy bills.”
