PG&E Unveils the SAVE Program for Energy Management
Pacific Gas and Electric Company (PG&E) has launched an innovative program named Seasonal Aggregation of Versatile Energy (SAVE). This first-of-its-kind virtual power plant (VPP) is designed to optimize the use of residential distributed energy resources, enhancing local grid reliability during peak demand periods.
Understanding the SAVE Program
SAVE aims to address local grid constraints by effectively utilizing residential home batteries and smart electric panels. The initiative will engage up to 1,500 electric residential customers with battery storage solutions and around 400 customers using smart energy panels. This strategic deployment will span several months, providing crucial localized support during peak demand times, specifically from June through October. The program envisions delivering 100 hours of dispatchable energy, which will help alleviate pressure on electric substations facing capacity challenges.
A Clean Energy Vision
Patti Poppe, CEO of PG&E Corporation, emphasized the significance of virtual power plants in California's journey towards a cleaner energy future. She stated, "We’re proud of our customers who are leading the charge with their clean energy adoption. Each day, we're exploring innovative ways to ensure safety and reliability for our communities while embracing sustainability."
How SAVE Operates
The innovative SAVE program operates through a collaboration with various aggregators, including notable companies like Sunrun and SPAN. These aggregators will receive information from PG&E about the energy capacity needs on a week-ahead basis, enabling them to adjust energy usage in real-time to suit the grid's requirements. This implementation leverages advanced software solutions from Tesla and SPAN, ensuring a seamless balance between energy demand and supply.
Target Areas for the SAVE Program
PG&E has identified specific neighborhoods across its service area for the implementation of the SAVE program. A key factor for selection is the capability to monitor and mitigate potential overloads that may arise during peak summer hours. The project particularly emphasizes equity, ensuring that a majority of the participating customers (60%) come from disadvantaged or low-income communities. By doing so, SAVE not only aims to optimize energy distribution but also works towards fostering energy equity.
Participation of Key Partners
Sunrun is set to play a pivotal role in the SAVE program by managing battery dispatches effectively. Their solar-plus-storage systems installed at homes will be equipped to deliver targeted load relief in neighborhoods grappling with electric grid constraints. Importantly, all enrolled batteries will maintain a 20% backup reserve, ensuring power availability in case of outages. Sunrun CEO Mary Powell remarked, "We are witnessing a transformative shift where homes transition from being mere energy consumers to becoming pivotal assets within the energy grid." This shift allows for reliable power delivery, which is especially crucial during peak grid demand.
Leveraging Advanced Technology
Another key player in the SAVE program is SPAN, which focuses on utilizing smart electric panels that respond dynamically to dispatch signals. By employing its Dynamic Service Rating™ (DSR) technology, SPAN can adjust home energy usage during peak periods, ensuring that overall energy consumption adheres to the operational limits of PG&E’s infrastructure. SPAN customers can utilize the SPAN Home app to manage their appliance usage effectively during high-demand situations.
