On–site Energy Solutions
On–site energy solutions (also known as ‘behind–the–meter’) are an increasingly important tool for organisations seeking to decarbonise operations, manage energy costs and improve security of supply to mitigate electricity market volatility. Technologies such as solar, wind, battery storage, heat networks, private wire arrangements and microgrids make it possible for energy to be generated, stored, distributed and consumed where it is needed, reducing exposure to wholesale market volatility and costs, and network constraints.
Scaling these solutions requires careful structuring of property, commercial and regulatory arrangements to balance risk, control and long–term value between energy users, asset owners, landlords, funders and suppliers.
Our on–site and behind–the–meter energy capabilities
Our multidisciplinary team advises energy users, developers, landlords, investors and technology providers on the design, delivery and operation of complex on–site and behind–the–meter energy schemes across the UK. We bring together expertise in clean energy, real estate, construction, finance and regulation to support projects in a wide range of commercial, industrial and infrastructure settings.
Our experience spans large distribution and logistics hubs, mixed–use developments, visitor attractions, live events venues, higher education campuses and multi–site roll–outs. We regularly advise on innovation and first–of–a–kind projects involving private wire supply, pioneering supply and offtake arrangements for power, gas and heat, heat and cooling networks, solar, on–site wind, energy storage and electric vehicle charging infrastructure.
