home-to-grid power plants technical

"home battery storage, solar, and home-to-grid power plants"

Home-to-grid power plants are systems that let individual houses act like small power stations by sending excess electricity they generate—usually from rooftop solar or home batteries—back into the wider electrical grid. For investors, they matter because they change how energy is produced and sold: they can create new revenue streams, reduce demand peaks, lower utility costs, and enable companies that supply equipment, software or grid services to grow, similar to how thousands of small shops together reshape a retail market.

distributed power plant technical

"first-of-its-kind distributed power plant partnership with Pacific Gas and Electric"

A distributed power plant is a group of small electricity sources—like rooftop solar, batteries, or small turbines—spread across different locations but coordinated to act like one larger power station. For investors, it matters because this approach can lower transmission costs, increase resilience and flexibility, and create new revenue streams from selling power or grid services; think of many neighborhood generators pooling output like a team instead of a lone player.

distribution upgrades technical

"helping PG&E avoid or defer distribution upgrades while generating net savings"

A distribution upgrade is an announced increase in the regular cash payout that a company, fund, or trust gives to its shareholders or unitholders, similar to a landlord raising the rent paid to tenants. It matters to investors because higher distributions directly raise income from holding the security and can signal stronger cash flow or management confidence, while also affecting yield and expectations for future payments.

machine learning technical

"Each location received different instructions based on machine learning, forecasted weather"

Machine learning is a set of computer programs that learn patterns from large amounts of data and improve their predictions or decisions over time, like a recipe that gets better each time it’s adjusted based on taste tests. For investors it matters because these systems can speed up analysis, spot trends or risks humans might miss, automate routine work, and potentially create competitive advantages or cost savings that affect a company’s performance.

View in glossary

distributed energy resources technical

"we already knew that distributed energy resources could help meet systemwide peak"

Small, local sources and devices that generate, store or manage electricity near where it’s used—examples include rooftop solar panels, batteries, electric vehicles, smart thermostats and backup generators. They matter to investors because they reshape how power is produced, sold and paid for: they can lower costs, create new revenue streams, change regulation and require grid upgrades, so they affect company profits, risk profiles and growth opportunities much like dozens of small engines changing how a single factory runs.

non-wires alternative technical

"support both non-wires alternative types of distribution and system-wide"

Non-wires alternatives are solutions that meet electricity needs without building new overhead or underground transmission lines, using options like local batteries, rooftop solar, demand reduction programs, and grid software to relieve congestion or add capacity. For investors, they matter because they can avoid large, long-term construction costs and regulatory delays, change the timing and size of utility spending, and create opportunities in distributed energy technologies much like choosing to upgrade traffic control instead of building a new highway.

grid services platform technical

"Sunrun’s grid services platform and subscription model allow for flexibility"

A grid services platform is a technology system that helps operate and optimize the electricity grid by coordinating generation, storage, and demand like a conductor directing an orchestra. It monitors supply and demand in real time, dispatches resources to keep voltage and frequency stable, and enables participants to sell or buy balancing services. Investors care because these platforms can unlock new revenue streams, lower operational costs, and reduce regulatory or outage risks for utilities and energy providers.

subscription model technical

"grid services platform and subscription model allow for flexibility when it comes"

A subscription model is a way a company sells access to products or services for a recurring fee, typically billed weekly, monthly, or annually — think of it like a gym membership for software, media, or goods. For investors, it matters because predictable, ongoing payments make revenue more stable and easier to forecast, and high customer retention can increase long-term value and justify a higher stock price.

Coordinated residential battery storage and solar systems supplied targeted power to neighborhoods with highly-constrained electric grids

SAN FRANCISCO and OAKLAND, Calif., Feb. 24, 2026 (GLOBE NEWSWIRE) -- Sunrun (Nasdaq: RUN), America’s largest provider of home battery storage, solar, and home-to-grid power plants, has completed a successful dispatching season of a first-of-its-kind distributed power plant partnership with Pacific Gas and Electric Company (PG&E). More than 1,000 Sunrun customers’ storage-plus-solar systems exported energy to alleviate local grid constraints, with the goal of helping PG&E avoid or defer distribution upgrades while generating net savings for all utility customers.

“Sunrun’s groundbreaking program with PG&E shows that distributed power plants can help communities avoid the high cost of adding more poles and wires to accommodate load growth,” said Sunrun CEO Mary Powell. “We saw time and time again that our customers’ batteries delivered location-specific load relief with high precision and consistent performance. Only Sunrun has this ability to quickly scale both large and bespoke distributed power plant programs with a variety of offtakers.”

Sunrun’s Local PeakShift Power distributed power plant is part of PG&E’s Seasonal Aggregation of Versatile Energy (SAVE) program. After testing from April to June 2025, the distributed power plant dispatched more than 50 times from July through October 2025, when local demand neared system capacity, totaling more than 1,200 dispatching hours. Sunrun customers with storage-plus-solar systems who live near or are connected to more than two dozen constrained power lines and substations in PG&E’s service area were enrolled in the program.

“Being able to provide energy to my local neighborhood just makes a lot of sense,” said Sunrun customer Tom Weldon, whose San Jose home sits near a constrained power line. “When heat waves arrive, we know that our batteries are going to help out when the grid is stressed. It’s something I feel really good about.”

A post-season program evaluation report by Demand Side Analytics found that Sunrun’s battery groupings closely followed PG&E’s dispatching instructions and kept electrical loads below the operating limits at all of the power lines and substations. Each location received different instructions based on machine learning, forecasted weather, and daily distribution system load forecasts. The batteries demonstrated a high degree of dispatch predictability and consistency—sending electricity to the correct location at the correct time during nearly 99% of events.

“Going into this project, we already knew that distributed energy resources could help meet systemwide peak electricity demand and put broad downward pressure on peak prices,” Powell added. “This program demonstrated that dispatching home batteries can also be a targeted tool to help avoid costly upgrades on the distribution network.”

“Working with partners like Sunrun is a win for our customers, our electric grid and California as a whole. This program shows how customers can help improve local grid reliability as we support the state’s growing need for energy,” said Patti Poppe, CEO of PG&E Corporation.

Due to customer interest, PG&E expanded Sunrun’s initial participation in the program from 600 customers to more than 1,000 during the enrollment period. Sunrun customers enrolled in Local PeakShift Power received $150 per battery for sharing their stored solar energy with their communities, while Sunrun was compensated for coordinating the battery dispatches. Sunrun’s collaboration with PG&E supports the development of long-term programs to meet the California Energy Commission’s load-shifting goals while also enhancing local reliability.

With more than 217,000 residential battery systems across the country, Sunrun can support both non-wires alternative types of distribution and system-wide distributed power plant programs. Sunrun’s grid services platform and subscription model allow for flexibility when it comes to enrolling customers in different programs in order to achieve the highest value for the company, its customers, and the grid.
