ERA Technology
London Power Associates is a leading engineering consultancy specialising in power systems and renewable energy. The company is now part of ERA Technology and the combined group includes some of the UK’s well-known industry specialists.

LPA provides a highly responsive and flexible service that allows you to make investment decisions with confidence at any time during the project’s life cycle. Our early involvement offers key advantages in terms of risk minimisation, optimisation of technical performance and cost, compliance with health, safety, environmental and information security requirements and standards.

LPA is registered with Achilles to provide services to the Energy Utility Business Sector (UVDB ID. 84884) and the UK Railway Sector (Link-up ID. 19987). LPA is also accredited to the UVDB Verify scheme and Supply-Line (ID 88763).

An exciting development took place on Friday 24th October 2014. LPA was acquired by ERA Technology.
