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 at COP26 by Ofgem, IEA, IRENA, RMI and the World Bank 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.

Network Planning
for wide scale electrification

Meeting the technical challenges of

Third RETA workshop on digitalization

On 14 September 2023, the third and final online RETA workshop in the series on digitalization took place, facilitated by the International Energy Agency and Energy Innovation. 32 participants joined from all over the world.

The workshop featured some high-level speakers focusing on technical solutions, including Audrey Zibelman and speakers from Energy Web, the Californian PUC and the regulator and independent system operator in Chile.  The need to build global standards for the digitalization of energy systems, and to get it right the first time round, was underlined. Specific examples of dynamic pricing, models for digital hubs and the use of blockchain were explored.

Following the presentations, the participants were divided into breakout rooms to engage in deeper discussions on the three case studies presented from Australia, California and Chile. Regulators can access materials from the workshop here.

Second workshop on digitalization

On 28 June 2023, the second online RETA workshop on digitalization was organized, facilitated by RMI and Energy Innovation, attracting the participation of 20 regulators.

During the workshop, the French energy regulator, the Australian energy regulator, and the Indian-based Council on Environment, Energy and Water presented case studies highlighting the advantages of digitalization in the energy system.

Following the presentations, the participants were divided into breakout rooms to engage in deeper discussions on the three topics presented: demand-side flexibility, the integration challenges of consumer energy sources, and advanced metering infrastructure.

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.

RETA at Canada’s CAMPUT Conference.

The association of Canadian federal, provincial, and territorial energy and utility regulators met in Toronto for their annual conference from the 7 to 10 May 2023.

The discussions were all around “New Regulatory Pathways for a Just Energy Transition”, and the RETA Administrator, as well as a fellow RETA regulator E-Control from Austria, were delighted to be part of the conversation. Whether and how decarbonisation is part of energy regulators mandates, and how Canada can become better interconnected between the provinces and territories were big topics of discussion, both key elements of RETA’s flagship projects.

More information on CAMPUT’s conference can be found here.

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.

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.

The World Forum on Energy Regulation

The World Forum on Energy Regulation (WFER) is the leading international conference on energy regulation and is held every three years. It brings together key players in the energy industry, high-level decision-makers, academics, and regulators from around the world to engage in strategic energy discussions on different regulatory schemes. The Forum is held within the framework of the International Confederation of Energy Regulators (ICER), a voluntary framework for cooperation among energy regulators, which aims to help improve the design and implementation of public policies in the energy sector by exchanging information and best practices.

This year’s edition, held in Peru and hosted by Osinergmin, will include a session organised by RETA. Further details will follow shortly.

Date: 22-26 May, 2023
