NYSEG and RG&E residential VPP economics

NYSEG and RG&E are regulated by the New York Public Service Commission (PSC) as separate companies, each with its own tariff and rate case. Their parent, Avangrid, is owned by the Spanish utility group Iberdrola and supplies capital and shared services to both. Above them sit the New York Independent System Operator (NYISO), which runs the wholesale market and the grid, and the New York State Energy Research and Development Authority (NYSERDA), which pays upfront storage incentives.

Every deep dive on this site has one feature that changes how its economics read. For NYSEG and RG&E it is the pair itself. The two names appear together on bills, websites and program pages, so many people treat them as one utility. For program pay they nearly are. For rates, grid value and future wholesale pay they are not.

NYSEG is the larger and more scattered of the two: about 921,000 electric customers in 44 counties, from the Southern Tier and the Finger Lakes to the Adirondacks and the Lower Hudson Valley. RG&E is compact: about 392,000 customers in nine counties centered on Monroe County (temporary rate order). The two filed rate cases on the same day in June 2025 but in separate dockets. NYSEG asked for an 18.4% increase in total electric revenue and RG&E for 19.8% (NY DPS); the PSC granted temporary increases of 3.7% and 4.0% from June 1, 2026, while it reviews the cases (WXHC).

The difference that matters most for flexibility is where each sits in the wholesale market. RG&E is entirely in NYISO Zone B, Genesee, home to the Ginna nuclear plant. NYSEG spans seven zones, and its Lower Hudson Valley customers are in the G–J Locality, a separate capacity zone.

In summer 2026 the zones priced the same: the G–J Locality cleared with Rest of State at a record $7.90 per kW-month in May and June (Potomac Economics), then fell to $4.14 in July (Modo Energy). In past years G–J has cleared higher. A future home aggregation in Westchester or Putnam County could earn more capacity pay than one in Rochester.

The links run through the parent and through the wires. Avangrid files the two utilities’ demand response reports, program rules and rate requests together, and a single credit watch covers both (Fitch Ratings). Critics argue that the New York companies are shells whose finance, planning and customer service sit with Avangrid (The Flaw). On the grid, RG&E’s Genesee zone borders NYSEG’s Central zone, with NYISO subzone ties at points such as Geneseo, Clyde and Macedon (NYISO subzones). The service areas meet in the Finger Lakes and around Monroe County, so two homes a few miles apart can have different utilities.

For a household the practical test is the bill: the utility named on it decides the rates, the OptimizEV window and the event calls. Our Residential VPP Calculator looks that up by ZIP.

Double dipping means one device earning twice for the same thing. In New York the question is whether a battery can earn from NYSEG or RG&E and from NYISO at the same time. The rules separate stacking, which is allowed for different services, from duplicate pay, which is not.

NYISO’s DER participation model opened in April 2024. It lets an aggregator combine resources as small as 10 kW into an aggregation of at least 100 kW, all behind the same transmission node, and sell energy, ancillary services and capacity (NYISO). Dual participation with a utility program is allowed: the aggregation tells NYISO and bids so that NYISO schedules it whenever it runs for the utility. A resource can’t sit in a DER aggregation and in the Special Case Resource (SCR) demand response program at once. NYISO’s rules for FERC Order 2222 take effect by the end of 2026 and will change the dual-participation rules (FERC).

For a home in NYSEG territory, the barriers are practical. NYSEG requires an interval meter with a dedicated communications line, real-time telemetry that takes months to set up, and an interconnection agreement for any site that exports; it says its wholesale distribution tariff is not yet approved and that duplicative compensation is prohibited (NYSEG DER aggregation page). A Powerwall 3 is rated at 11.5 kW, so a single battery could clear the 10 kW floor, but it would need an aggregator and about nine neighbors on the same node. By April 2026 only six aggregations had enrolled statewide, all demand-side (NYISO filing).

Stacking needs care, depending on M&V methodology. Energy Storage Solutions measures a battery’s average discharge during events; NYISO would settle the same kilowatts at the same meter. Until Order 2222 rules and a residential aggregator arrive, a home battery earns the utility’s $50 per kW and NYSERDA’s upfront incentive, and nothing from NYISO.

Smart Savings Rewards runs on EnergyHub’s platform. About 40,000 thermostats are enrolled (News10NBC), and the two utilities paid about $570,000 in incentives in the 2024–25 program year (NYSEG and RG&E). Events run on non-holiday weekdays from May through September, with no more than 80 event hours a season (GreaterGrid).

OptimizEV, run by ev.energy, pays the gap between the standard rate and the time-of-use rate on each off-peak kWh. The windows differ: 11:30 p.m. to 7 a.m. every day at NYSEG (NYSEG program terms), and 9 p.m. to 7 a.m. on weekdays plus all weekend at RG&E (RG&E home charging page). In 2024, 604 NYSEG and 436 RG&E customers took part, and no demand response events were called (2025 managed charging filing).

Energy Storage Solutions launched in August 2025 for Tesla, Enphase and SolarEdge batteries up to 25 kWh (RG&E storage page). NYSERDA’s example, 13.5 kWh discharged at 80% over three hours, gives 3.6 kW and about $180 a year (NYSERDA); Tesla quotes up to $180 per Powerwall (Tesla). The federal 25D credit ended with 2025 (IRS), and New York’s 25% solar equipment credit is written for solar equipment; whether a battery counts depends on how it is charged (NY Department of Taxation).

Take one hypothetical single-family home with central air, a Google Nest Learning Thermostat and a Tesla Model Y on a ChargePoint Home Flex charger, driven 12,000 miles a year. We ran it through our Residential VPP Calculator in Rochester (ZIP 14618, RG&E) and Ithaca (ZIP 14850, NYSEG).

The same home earns $315 more in Ithaca than in Rochester, all from OptimizEV. The thermostat pays the same everywhere.

A positive cash test asks whether pay and incentives cover the cost within ten years. The chart below compares each device with its installed cost; past the 100% line, it is cash-positive.

Thermostat: yes, or close. A thermostat already on the wall is cash-positive from day one. A new $280 Nest recovers about 96% from the program alone, and any heating and cooling savings tip it over.

EV charging: yes at NYSEG on the advanced tier. The advanced tier recovers about 112% of a $1,500 charger in NYSEG territory and about 89% in RG&E territory. A household with an EV needs a charger anyway, and fuel savings over gasoline are far larger than the credits, so the program is a bonus on a purchase that already pays.

Battery: no, not on grid pay. Even at the inclusive NYSERDA rate, a Powerwall 3 is about $7,926 short after ten years; at the standard rate, about $11,301. Upstate New York’s flat standard rates leave little to save by shifting, so the battery is a backup purchase that grid pay partly offsets.

Energy Storage Solutions pays $50 per kW; a ten-year payback would take about $360 at the standard NYSERDA rate, more than Massachusetts pays for the same battery. NYISO capacity, even at the 2026 record, adds about $28 per kW a summer. The gap is too wide for wholesale pay to close on its own; a lower installed cost would do more.

We found no hosted-battery program with a monthly fee, like Base Power’s in Texas, in either territory, so the choice here is between owning and borrowing. The inclusive NYSERDA rate is the strongest lever: it cuts the ten-year shortfall by about 30%.

NYSEG and RG&E received requests for almost 500 MW of new load in 2024 (Avangrid testimony). NYSEG is procuring at least 10 MW of bulk storage by 2030 (NYSEG bulk storage page) and seeking a non-wires alternative for the Liberty area for 2026–2036 (NYSEG Liberty RFP). Those are the places where home flexibility could be worth more than the systemwide $50 per kW.

The future of VPP to grow at scale will depend on multiple assets in unison at any given site: thermostat, EV, battery and, eventually, water heater, dispatched together and measured as one resource. NYSEG and RG&E have three of the four programs but run them separately on different platforms. Whole-home enrollment, a water heater program, and a residential aggregator under NYISO’s Order 2222 rules would move the territory from demand response toward an orchestrated VPP.
