Virtual Power Plant Platform

Your subscriber solar fleet, dispatched as one.

Nexwatt aggregates behind-the-meter solar, storage, and load across subscriber accounts into a single ISO-recognized virtual power plant — giving community solar operators access to PJM, ISO-NE, and NYISO capacity markets.

Platform Capabilities

Built for the ISO capacity market pathway

Aggregate Dispersed Assets

Connect BTM solar, BESS, and flexible load across your entire subscriber portfolio — regardless of inverter brand or metering protocol.

Qualify as Capacity Resource

Nexwatt handles ISO enrollment documentation, telemetry compliance, and dispatch testing — the technical pathway from raw DER to registered capacity resource.

Earn Capacity Market Revenue

Dispatch your virtual power plant into PJM BRA, ISO-NE FCM, or NYISO ICAP auctions. Capture capacity payments your program was leaving on the table.

Program Outcomes

Who runs on Nexwatt

Community Solar Operator

Solaris Corridor Energy

Mid-Atlantic community solar developer managing 85 MW across 4,200 subscriber accounts seeking PJM capacity qualification.

Enrolled 61 MW as PJM Capacity Resource within 14 months of program launch.

"Nexwatt handled the entire ISO enrollment workflow. We focused on subscriber growth — they handled the capacity market pathway."

— Director of Energy Operations, community solar program

DER Aggregator

Verdant Grid Services

Independent DER aggregator managing behind-the-meter storage and load flexibility across commercial subscribers in ISO-NE territory.

Reduced ISO telemetry compliance preparation time from 6 weeks to under 10 days.

"The normalization layer alone saved us months. Every ISO has different telemetry specs — Nexwatt abstracts that completely."

— Head of Grid Operations, DER aggregation firm

Regulatory Context

FERC Order 2222 opened the door. Nexwatt walks you through it.

FERC Order 2222 requires ISOs to allow DER aggregations to participate in wholesale markets. Most community solar programs lack the technical infrastructure to qualify. Nexwatt is purpose-built to close that gap — from metering normalization to ISO dispatch protocol compliance.
