Virtual power plants (VPPs) provide grid services at a lower cost, and can be deployed faster, than conventional generation. Studies have found that VPPs can provide resource adequacy at 40% to 60% of the cost of alternatives like gas-fired peaking plants or peak shaving batteries. In addition, they can be deployed in a matter of months, far faster than the 3–5+ years that it takes to deploy conventional generation.
On 20 November 2025, the Regulatory Assistance Project and Regulatory Energy Transition Accelerator offered a webinar on how VPPs can deliver cost-effective flexibility, in both market-oriented electricity services and in vertically integrated systems. Additionally, we explored how Thailand can incorporate this technology into its vertically integrated system.
We shared insights from our new report, Unlocking Cost-Effective Grid Flexibility in Thailand: Virtual Power Plants and the Role of Regulators. Experts highlighted experience with different business models, including:
- Hawaii’s utility-led VPP model
- Australia’s market-led VPP model
- Policy pathways for VPPs in Thailand
- Practical recommendations for regulators interested in advancing VPPs in their jurisdictions
Here is our list of speakers and panelists.
