Distributed Energy Resource Aggregation (DERA) for Homeowners (2026)

The electric grid is increasingly being shaped from the bottom up. Rooftop solar, home batteries, smart thermostats, EV chargers, and heat pump water heaters are no longer just cost-saving appliances — they’re grid assets. Distributed Energy Resource Aggregation (DERA) is the mechanism that bundles thousands of these small devices into a single controllable pool that can respond to grid needs as effectively as a gas peaker plant. For homeowners in deregulated markets, DERA programs represent a new revenue stream that didn’t exist a decade ago.

What Is a Distributed Energy Resource (DER)?

A distributed energy resource is any small-scale power technology located on the customer side of the meter that can generate, store, or adjust electricity consumption on demand. The most common residential DERs include rooftop solar photovoltaic systems, home battery storage (Tesla Powerwall, Enphase IQ Battery, LG RESU, Franklin WH, etc.), smart thermostats enrolled in demand response programs, heat pump water heaters with scheduling capability, EV chargers (both one-way managed charging and bidirectional V2H/V2G-capable chargers), and pool pumps and water softeners on smart scheduling.

Individually, a single 10 kWh home battery is trivially small compared to a 100 MW gas turbine. But aggregate 10,000 home batteries in a single metropolitan area and you have the equivalent of 100 MW of dispatchable peak-shaving capacity — available within seconds, with no fuel cost, no emissions, and no new transmission infrastructure required.

What Is DER Aggregation?

Aggregation is the process of virtually combining many individual DERs under a single entity — typically a technology platform or energy services company called a DER aggregator — that can bid their collective capacity into wholesale electricity markets or grid operator programs. The aggregator handles the technical complexity of coordinating thousands of devices, submitting resource offers to the grid operator, responding to dispatch signals, and calculating settlement payments. Individual homeowners interact with the aggregator through a simple enrollment process and receive payment without needing to understand the underlying wholesale market mechanics.

FERC Order 2222, finalized in 2020, is the landmark federal regulatory action that opened wholesale markets to DER aggregations. It required Regional Transmission Organizations (RTOs) and Independent System Operators (ISOs) — the entities that run regional electricity markets — to allow DER aggregations to participate directly in energy, capacity, and ancillary services markets on equal footing with traditional power plants. Implementation has been phased across regions, with PJM, CAISO, and NYISO moving furthest along as of 2026.

Market Products DER Aggregations Can Participate In

The specific market products available to DER aggregations depend on the regional grid operator. The main categories:

Capacity markets: Grid operators run annual or periodic auctions to procure committed capacity for future peak periods. DER aggregations that can guarantee a certain level of load reduction or generation during peak events can sell capacity commitments. PJM’s capacity market (the RPM auction) and ISO-NE’s Forward Capacity Market have both begun accepting DER aggregations.

Energy markets (economic dispatch): An aggregation that can dispatch stored energy from home batteries can bid into day-ahead and real-time energy markets, selling power at times when wholesale prices are high and absorbing power when prices are low. This is arbitrage at scale.

Ancillary services: Fast-responding resources are paid for frequency regulation, spinning reserves, and non-spinning reserves. Home batteries and smart thermostats can respond in seconds to regulation signals — comparable to large power plant governor response — making them well-suited for frequency regulation markets where response speed commands premium payments.

Demand response programs: Many utilities and grid operators also run utility-managed demand response programs (separate from wholesale markets) that pay customers for curtailment during peak events. These are often simpler entry points than full wholesale market participation and are available in many states regardless of deregulation status.

How Homeowners Participate

Direct homeowner participation in FERC Order 2222 wholesale markets requires enrollment through an aggregator. Several companies operate as residential DER aggregators: OhmConnect (active in California, Texas, and New York), AutoGrid, Sunrun (for solar + storage customers), Swell Energy (acquired by OPOWER/Oracle), and utility-affiliated virtual power plant programs like Green Mountain Power’s Bring Your Own Device program in Vermont.

The enrollment process typically involves: (1) registering your DER devices (solar inverter, battery system, smart thermostat) with the aggregator’s platform; (2) granting the aggregator permission to dispatch your devices within defined parameters (e.g., “dispatch my battery down to 20% state-of-charge during grid events, but maintain my home comfort setpoints between 68°F and 76°F”); (3) receiving payment — usually monthly or quarterly — based on your resource’s measured performance during dispatch events.

Payment structures vary. Capacity payments provide fixed monthly revenue for being enrolled and available. Performance payments are based on actual dispatch contribution. Some programs combine both.

Real-World Examples

Green Mountain Power (Vermont) has enrolled thousands of Tesla Powerwall customers into its Emergency Electricity Program, paying homeowners $850/year to reserve 60% of their battery’s capacity for grid emergency events. During peak grid stress (typically hot summer days), GMP can dispatch the reserved capacity; outside those windows, the battery operates normally for the homeowner’s benefit.

OhmConnect’s model rewards California, Texas, and New York customers for curtailing usage during grid stress hours. Customers earn points (redeemable for cash, gift cards, or smart devices) for each watt-hour they reduce below their historical baseline during called OhmHours. Top participants earn $100–300/year through behavioral curtailment alone; those with batteries or EVs can earn significantly more.

In New York, Con Edison’s PowerReady program offers managed EV charging credits and demand response payments for commercial EV fleet operators, with a residential equivalent emerging under NYISO’s Order 2222 implementation.

Considerations for Homeowners

Participating in a DERA program means giving an external entity limited dispatch authority over your home devices. The critical question is: what are the controls and guarantees? Reputable aggregators define explicit dispatch limits (minimum battery state of charge, HVAC temperature bounds, number of dispatch events per month) and provide advance notice where technically feasible. Read the enrollment agreement carefully for dispatch frequency, override rights, and exit terms.

Also consider the interaction with your utility’s net metering program and electricity supplier contract. Some DERA dispatch events may affect your net metering exports or TOU billing in ways that reduce rather than enhance total compensation. An aggregator with a transparent settlement calculator is preferable to one that obscures how payments are calculated.

Frequently Asked Questions

Do I need solar panels to participate in a DERA program?

No. Many DER aggregation programs accept battery storage without solar, smart thermostats, or managed EV charging independently. Solar panels without storage are less valuable for dispatch because output depends on sunlight, but solar plus storage is the most flexible combination.

What is FERC Order 2222 and why does it matter?

FERC Order 2222 (2020) required grid operators to open their wholesale markets to DER aggregations, removing prior barriers that excluded small distributed resources from market participation. Before Order 2222, DERs were largely limited to utility-managed demand response programs with limited compensation. The order effectively created the regulatory framework for a nationwide virtual power plant industry.

Is DERA available in Texas (ERCOT)?

ERCOT has its own demand response and ancillary services programs that accept aggregated DERs, though ERCOT’s market structure differs from PJM/ISO-NE/NYISO since FERC’s jurisdiction over ERCOT is limited. The ERCOT Demand Response program and emerging battery storage dispatch programs provide similar economic opportunities for Texas homeowners with batteries and smart devices.

How much can a homeowner realistically earn?

Highly variable. A homeowner with solar plus a 10 kWh battery enrolled in a well-compensated capacity market program might earn $300–1,200/year in capacity and performance payments, depending on dispatch frequency and wholesale prices in that year. Smart thermostat-only participants in demand response programs typically earn $50–150/year. EV managed charging programs in high-peak regions can generate $100–300/year. These are supplemental revenue streams, not primary income — but they’re essentially passive once enrollment is complete.

Can my competitive electricity supplier also be my DERA aggregator?

Some can — particularly in states like Texas where retail electric providers (REPs) offer combined energy supply + demand response products. In most deregulated states, however, DERA aggregation is offered by separate technology companies or utility subsidiaries rather than commodity electricity suppliers. The two roles are legally and structurally distinct in most RTO tariff frameworks.
