Building on the successful ISGAN Knowledge Exchange in 2019, a follow-up project is now underway to capture recent developments and support countries in their development of regulatory sandboxes and related experimental instruments, which are key to enable up-scaling and deployment of smart grid and wider energy system innovation.

The focus of this project, involving 16 countries on four continents, is to share experiences and ideas between countries on how to maximise different aspects of learning from sandbox programmes. The process combines international knowledge exchange workshops with stakeholder dialogue at national level to customise the learning to specific contexts and preconditions in the participating countries. Focus questions include how sandbox programmes can be integrated into longer term energy transition strategies, the legal preconditions and exemption laws to enable sandbox programmes, how to coordinate between different stakeholders in programme implementation, and how to design evaluation processes for policy learning.

The second international workshop of the ISGAN Regulatory Sandbox 2.0 project was held on 15 March 2021, involving 30 experts from ministries, regulatory bodies, energy agencies and the research community in a highly interactive dialogue on country-specific as well as shared challenges and experiences.

Apart from concrete learning for the participating countries, the project will deliver concrete policy messages to the Clean Energy Ministerial meeting later this spring. The project results will also be disseminated widely through a public workshop arranged by the ISGAN Academy and a new ISGAN Casebook on Regulatory Sandboxes.

Webinar- Advanced weather forecasting for RES applications: Smart4RES developments towards high-resolution and Numerical Weather Prediction solutions to improve RES forecasting models

23 Mar. 2021 12:30 CET This 3rd Smart4RES webinar will address technological and market challenges in RES prediction and will introduce the Smart4RES strategy to improve weather forecasting models with high resolution. Through wind and solar applications, Innovative Numerical Weather Prediction and Large-Eddy Simulation approaches will be presented.

Intended audience

Academy members from the power systems and meteorological areas, forecasting services providers, renewable plant operators and market traders, and widely TSOs, DSOs and regulators.


Key messages

  • RES are sensitive to high-frequency and very localized variations of the atmospheric flow (wind guts, cloud shadows, fog occcurrence etc.)
  • Refining parameterizations used in NWP models is the first step to improve RES prediction
  • Getting rid of these parameterizations, for instance using Large-Eddy Simulations (LES), is a promising venue because it allows to resolve most of these small-scale fluctuations
  • The spectacular growth in computing power using GPUs now enable LES based weather prediction below 100m resolution. This is fine enough to resolve the effects of wind turbines, low clouds and turbulence.
  • Using ensemble simulations translates atmospheric state inherent unpredictability into a probabilistic view
  • The spectacular growth in computing power using GPUs now enable LES based weather prediction below 100m resolution. This is fine enough to resolve the effects of wind turbines, low clouds and turbulence.
  • A fourth webinar scheduled in April will complete this webinar on Advanced weather forecasting for RES applications and present how observations data can be used, together with measurements from RES plants, as input to dedicated RES forecasting models to predict the power output of these plants.

Webinar- Innovative solutions for increased regional cross-border cooperation in the transmission grid: the FARCROSS project

1 Mar. 2021 12:30 CET- The webinar will provide insight into the FARCROSS Horizon 2020 EU research project. Driven by recent development in EU internal market for electricity regulation, increased cooperation is key element for improving the interconnectors’ utilization and market harmonization. FARCROSS project looks into these challenges and promotes integrated hardware and software solutions in 5 pilot demonstrators across 8 European countries.

Intended audience:

  • Transmission System Operators (TSOs)  
  • Regional Security Coordinators (RSCs) 
  • Market operators  
  • Energy producers, traders and energy market actors 
  • Policy makers and regulation bodies 
  • Transmission and Distribution (T&D) equipment and services industry 
  • Academia and engineering communities

ISGAN launches a new ANNEX: Flexibility Markets- development and implementation

After the last ISGAN Ex.Co. it was decided to start a new annex: “Annex 9: Flexibility Markets- development and implementation” dedicated to all aspects of market design for power system flexibility.

International collaboration is a powerful tool in understanding issues around flexibility market design. Understanding the implications of design decisions is greatly enhanced by access to insights from the widest possible range of existing markets and the ability to capture the whole spectrum of different market contexts, which will help generate a body of evidence that is rich and diverse in scope. It is foreseen that this body of evidence will in turn be useful to all partner countries in evaluating different architectures for their own systems.

The scope of this Annex is all aspects of market design for power system flexibility. This includes:

  • the whole range of market timescales, from long term investment signals to second-to-second balancing and response;
  • the whole physical system from large centralized generation to behind the meter sources of flexibility within domestic settings and interfaces with other vectors;
  • all sources of value that flexibility conceivably could capture, going beyond MWh to include characteristics like voltage control, repeatability, inertia, locational constraint alleviation;
  • and aspects of the market that go beyond the trading rules such as consumer support, or how obligations (such as with respect to grid stability) are understood and checked

The new operating agent will be Dr. Iliana Cardenes from the UK Department for Business, Energy & Industrial Strategy (BEIS).

Beneficiaries of this Annex will be all ISGAN participants, the IEA and the Clean Energy Ministerial, colleagues working in related campaigns such as the Power Systems Flexibility Campaign and Mission Innovation, and any stakeholders involved in the design and operation of energy markets. These comprise government departments at supranational, national and sub-national level (including cities), as well as regulatory authorities, and potential market participants who are currently experiencing difficulties in getting flexibility to market.

Results will be made available in the form of webinars, workshops, publications (Policy briefs, white papers, etc.), scientific publications, presentations at conferences, and social-media facilitated peer-to-peer discussion groups.

New initiative to advance policy development on regulatory sandboxes

The objective of the project is to facilitate a structured and learning-focused knowledge exchange on sandbox programs and similar measures of regulatory experimenting in different countries.


Building on the successful ISGAN Knowledge Transfer Project (KTP) in 2019, involving more than 20 countries, and subsequent work on regulatory sandboxes in collaboration with ETIP-SNET, ISGAN is now starting a new initiative to deepen the learning and international exchange on this key topic for the energy transition.

Regulatory sandboxes and similar instruments are key to enable and accelerate upscaling and deployment of smart grid and energy system innovation. The project starts with an introductory webinar on 28 January 2021 and will conclude with the delivery of fresh insights and policy messages on regulatory sandboxes for advancement of smart grid solutions to the 12th Clean Energy Ministerial meeting in May 2021.

Please contact Helena Lindquist (helena[at], Magnus Olofsson (magnus.olofsson[at] or Klaus Kubeczko (Klaus.Kubeczko[at] in the ISGAN Regulatory Sandboxes Project Team for more information.
