TNEI also owns and develops the power systems analysis software, IPSA 2, which contains an extensive range of fully integrated modules enabling all essential studies to be undertaken and can be used to provide bespoke modelling solutions.

TNEI operates from offices in Manchester, Newcastle, Glasgow, Dublin and Cape Town. Our clients range from large utility companies, large and small project developers, industrial organisations and manufacturers, regulators, public sector bodies and community groups.

We have been operating in the energy industry since 1974 when IPSA software was first created at the University of Manchester Institute of Science and Technology (UMIST), where The Northern Energy Initiative (TNEI) began pioneering research into renewable energy in 1999. As a result of collaboration between these two entities, TNEI Services Ltd and IPSA Power were merged in 2004 and we have been delivering high quality consultancy services to our clients around the world ever since.
