Association of Electricity Producers

Association of Electricity Producers (AEP) logo

The Association of Electricity Producers (AEP) was a trade association (an organization that helps different companies in the same industry to collaborate) of electricity producers in the UK. It was founded in 1987 and became part of Energy UK in 2012. Before merging, AEP had about 90 member companies.

About the Association of Electricity Producers

The Association of Electricity Producers included companies that generated electricity as well as companies that supplied support services in the electrical energy industry.

Originally it was known as the Association of Independent Electricity Producers (AIEP) when it was founded in 1987. It was created to lobby the United Kingdom government, specifically the Department of Energy, to remove regulations and restrictions limiting private companies in the energy market.


The main founder was David Andrews, who was attempting to introduce small-scale Combined Heat and Power into the UK market and was frustrated by the restrictions of the Central Electricity Generating Board. He held the first meeting in London with representatives from Orchard Partners, Wessex Water and Electrical Review.

Once they helped to pass the Electricity Act in 1989, the energy industry became fully privatised, with the exception of nuclear power.


If you’re wondering what happened to the Association of Electricity Producers, they’re now part of Energy UK. In 2012, AEP merged with the Energy Retail Association and the UK Business Council for Sustainable Energy to form an energy trade association with over 100 members, Energy UK.

Much like the AEP before it, Energy UK is a trade association dedicated to helping members of the energy sector to work collaboratively. They describe their members as “suppliers, generators, and stakeholders with a business interest in the production and supply of electricity and gas for domestic and business consumers”. They also claim their membership covers 90% of power generation in the UK and the domestic energy supply market.

Energy UK provides their member companies with an expert staff available for query, committee meetings to discuss the latest energy trends, a weekly newsletter on the most current industry news and special events for members.
