Coming Together to Focus Our Efforts and Refine Our Goals

In September, we gathered nearly 35 G-PST Consortium leaders in London to take an opportunity to reflect and think critically about where we are now and where we are going. It was evident we have tremendous opportunity in front of us and still much work to be done. Together, we agreed on new, aggressive engineering and dissemination goals to focus our efforts in line with our fundamental mission of rapidly accelerating the clean energy transition. I’m excited to share these goals with you:

  • Engineering Goal: Operate a 100% inverter-based resources transmission system by 2025
  • Dissemination Goal: Share learnings and technical accomplishments globally to drive step-change in decarbonization of energy systems.

Our strategy session also enabled us to take a hard look at where we are succeeding and where we could be more effective as the G-PST grows. Over the next year, we will be working to ensure even stronger integration among our five G-PST pillars; we will continue building strong partnerships with complementary initiatives so we can build upon each other’s progress; and we will clarify and crystallize what impacts we are measuring as we move forward with new research and projects.

We all walked away from this strategy session inspired by how far G-PST has come in the past two years and motivated to explore how we can push further and reach the next level. If you have any questions about our goals or want to know how you can get more involved, reach out to our team at We are thrilled to have support from so many excellent partners and stakeholders throughout this ambitious journey!

Towards 100% Green Electrons

Published through MegaVind in June 2022; Written, in part, by G-PST Consortium partners at DTU, Energinet, and Ørsted

Denmark and many other countries are currently in the process of transforming our energy systems into a system dominated by wind and solar coupled with additional variable demand from P2X, heat pumps, electrical vehicles, and other electricity consumers. This transformation presents numerous challenges to the future operation of the electrical grid, requiring the deployment of new tools, methods, and technologies.

This Megavind report sets out to achieve two things. First, to break down the system complexity into two categories: variability and stability. Hopefully, this will provide non-expert readers with a framework to navigate the complex nature of the topic. Second, to outline the potential solution spaces for the development of the electrical grid towards becoming 100% renewables-based and provide specific recommendations for the realization of that goal. Explore the report.

Incorporating Renewable Energy Sources and New Tech into the Electric Grid

Published through T&D World in August 2022; Written, in part, by G-PST Consortium partners at NREL and IEEE

With society calling for more sustainable energy solutions, the utilities industry and the entire energy production, transmission, and distribution system are undergoing a fundamental transformation to the use of new technologies and a higher level of decentralized energy infrastructure and customer participation in the power system.
