Regulatory Energy Transition Accelerator

About RETA.

The accelerator is an initiative to enhance the capacity of regulators to increase the speed of the clean energy transitions.

It works directly with energy regulators in order to facilitate knowledge sharing, peer to peer learning and thought leadership on regulatory issues. It acts as well as a central resource for regulators to seek knowledge products and regulatory tools that can help mitigate challenges regulators face when trying to regulate for the sustainable, affordable and secure energy systems of the future.
The Accelerator was launched in 2021 at COP26 by Ofgem, IEA, IRENA, the World Bank, RMI, Energy Innovation and RAP along with regulators from around the world as part of the Green Grids Initiative.

What we do?

Areas of work.

The Accelerator is intended to enhance the capacity of energy regulators to contribute to decarbonisation of energy systems effectively, swiftly, and fairly through enhancing exchanges and communicating best practices in the following areas.

Report launch: Institutional Architecture for Regional Power System Integration – Government, Utility and Regulator Roles

As part of the RETA Flagship Project on Interconnectors, IEA has collaborated with the World Bank’s Energy Sector Management Assistance Program (ESMAP) and IRENA to produce this first guidance notes, as part of a series to help key stakeholders navigate the challenges associated with regional power system interconnectors. This knowledge product focuses on the soft infrastructure of cross-border power exchange, in accordance with the priority topics identified through a survey of regulators in February-March 2023. The guidance note can be accessed here.

Under this flagship project, the IEA, ESMAP and IRENA will continue to collaborate for the upcoming guidance notes planned for early next year.

Energy transition training in Budapest

RETA was proud to collaborate with the Energy Regulators Regional Association (ERRA) to organise their first training session for energy regulators focusing on the energy transition. The training took place over the course of a week in Budapest and online, with lively discussions and expert presentations. RETA delivery partners IEA, IRENA and the Regulatory Assistance Project contributed to the teaching, and regulators from Austria, Azerbaijan, Hungary, Latvia, North Macedonia, Romania, Turkey, Ukraine and West Africa participated.


We hope to make a small selection of the presentations available to all RETA participants in the future knowledge hub. Energy regulators have to be equipped to deal with and accelerate the energy transition, and this training was an important step in achieving that.

MECS becomes RETA delivery partner

RETA is delighted to welcome Modern Energy Cooking Services (MECS) as a new delivery partner.

Worldwide, nearly three billion people rely on traditional solid fuels, such as wood or coal, for cooking and heating. This has severe implications for health, gender relations, economic livelihoods, environmental quality and global and local climates. RETA is excited to partner with MECS to support regulators trying to encourage the move to electric cooking and reduce these dangerous emissions.

The work started in February with a meeting with African regulators, stay tuned for more updates soon.


February 2023

Meeting with African regulators on electric cooking

RETA facilitated the participation of African energy regulators at a meeting held in South Africa by the Climate Parliament and Modern Energy Cooking Services in February.

The meeting focused on the transition from polluting cooking fuels to electricity. Regulators from Kenya, Uganda, Rwanda, Malawi, Sierra Leone and Nigeria attended, as well as secretariat members from RETA and the African Forum of Utility Regulators.

The issue was identified as a pressing issue for many African regulators, with interesting examples being shared between regulators, and RETA will work further on electric cooking.

RETA launch at the COP26.

The International Energy Agency (IEA), International Renewable Energy Agency (IRENA), Ofgem and World Bank launched at the COP26 a global initiative “Regulatory Energy Transition Accelerator” to accelerate the energy transition to provide clean, secure, and affordable supplies to everyone. Energy regulators have a key role to play in turning ambition into real-world action in hitting global climate goals. The Regulatory Accelerator enables them to collaborate to seize opportunities and solve problems to speed up the global energy transition at the lowest cost.

In particular, it can help countries with less developed energy systems to leapfrog the carbon-intensive paths other countries have previously taken.

The joint statement launched at COP26 can be found here.
