REEEP was originally launched by the government of the United Kingdom, along with other partners, at the Johannesburg World Summit on Sustainable Development (WSSD) in August 2002.
REEEP develops and implements programmes which use a combination of financial instruments, capacity building, facilitation of stakeholder cooperation and technical assistance to encourage private sector investment in clean energy markets, primarily in low- and middle income countries.
[2] From January 2003 until May 2004, the REEEP was housed within the UK Foreign and Commonwealth Office (FCO) where it continued following the UN Type II Partnership[5] process of stakeholder consultation.
Regionally, REEEP has shifted concentration to low- and middle-income countries, although it continues to work in India and South Africa, which are generally considered to be emerging markets.
[12] The programme has been expanded into the Beyond the Grid Fund for Africa[12] which as of 2024 aims to reach over 8.6 million people across Burkina Faso, DRC, Liberia, Uganda and Zambia.
