Dive Brief:
- NRG and Renew Home are teaming up to roll out smart thermostats across Texas, aiming to establish a virtual power plant (VPP) with nearly 1 GW of capacity by 2035.
- This initiative, backed by Google Cloud, will start installing Vivint and Nest smart thermostats in selected homes starting in spring 2025. The VPP could expand to include home batteries, electric vehicles, and other energy resources.
- With the help of Google Cloud’s data and AI tools, NRG aims to enhance weather forecasting and pricing models to boost the effectiveness of the Renew Home VPP and other future projects.
Dive Insight:
The NRG and Renew Home VPP will have the power equivalent to 12 gas-fired peaker plants or nearly 300 wind turbines. “As the population grows and we face weather challenges in Texas, VPPs can provide a reliable and adaptable energy source,” said Renew Home CEO Ben Brown.
Utilities and policymakers are keen on expanding VPP capacity as a quick and affordable solution to manage increasing energy demand and reduce grid congestion.
Raising VPP capacity to between 80 GW and 160 GW by 2030 could save up to $10 billion annually in grid expenses, according to the U.S. Department of Energy. Additionally, research from the Brattle Group indicates that VPPs could help avoid substantial utility capacity investments and lead to significant annual savings in California alone by 2035.
With around 82 million residential HVAC systems significantly impacting energy usage peaks, there’s a substantial opportunity to enhance VPP capacity through the implementation of smart thermostats that can shift energy loads efficiently. This approach is expected to strengthen the overall network while also potentially decreasing customer electricity bills by over $10 billion.
The demand for energy in Texas has surged due to rapid population growth and industrial development. Recently, ERCOT revised its 2030 load forecast, increasing it by 40 GW to an expected total of 152 GW.
ERCOT is exploring various solutions, including faster interconnection methods, collaborative studies on energy efficiency, and potential new high-voltage transmission lines. Experts argue that building new distributed energy resources into VPPs can be quicker than constructing new transmission infrastructure, as deployments can be realized within as little as six to twelve months.
