What is RETA?

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.

The initiative’s goals have been confirmed as accelerating:
• flexible, renewable-based systems;
• regulatory frameworks to deliver the energy transition;
• network planning for wide scale electrification;
• regional interconnection
• a fair and inclusive energy transition
These objectives are to be delivered through dissemination workshops, bilateral and multilateral exchanges, bespoke technical assistance and knowledge products. 

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
expanding power systems.

Flexible, renewable-based systems

Managing increasing levels of variable renewables.


Making best use of regional resources.

Regulatory frameworks
to deliver the energy transition

Creating fair and regulatory structures.

Fair and inclusive energy

Ensuring that equity is at the heart of energy transitions.

Eastern Caribbean peer to peer exchange

The Global Green Growth Institute and the Organisation Eastern Caribbean States organised an interactive session on 2 November for energy regulators to discuss Regulatory Guidelines on Interconnection of Customer-Owned Renewable Energy Facilities to the Grid. This knowledge exchange will help form a basis for RETA’s flagship project on Small Island Developing States.

October 26-28, 2022

Renewable Energy Investment Conference

RETA was presented at the Renewable Energy Investment Conference 26-28 October, organised by the Energy Regulators Regional Association and the Council of European Energy Regulators, and hosted by RETA Steering Committee member, the Georgian National Energy and Water Supply Regulatory Commission. More information can be found here.

Facilitating renewable investment is key for regulators to fulfill our goal of flexible, renewable based systems. The conference was a big step forward in deepening regulators’ knowledge, and learning from each others’ experiences.

Presentation of IRENA’s report “RE-organising Power Systems for the Transition” at ICER’s July workshop

RETA partnered with the International Confederation of Energy Regulators to provide a dissemination workshop on the International Renewable Energy Agency’s Reorganising Power Systems for the Transition report in July. IRENA’s report explores enablers and barriers to the transition, and proposes a new power system organisational structure, fit for the renewable era, that can support low-cost renewable generation and long-term investments in system adequacy, complemented by diverse and flexible generation options to ensure a reliable power system to support the energy transition.

First meeting of RETA Steering Committee

RETA’s Steering Committee held its first virtual meeting on Monday, 9 May 2022. The Steering Committee is composed of energy regulators from Great Britain, Australia, California, Egypt, France, Georgia, Kenya, Peru, Saint Lucia, and Singapore, for two-year renewable terms, together with the International Energy Agency, International Renewable Energy Agency and the World Bank. The Steering Committee, chaired by Jonathan Brearley, CEO of Ofgem, discussed and adopted the activities for the first year as well as RETA guidelines and rules defining its functioning.

The Steering Committee will meet at least twice a year. The date of the next meeting will be determined at a later stage.

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.
