Texas operates on the deregulated ERCOT grid — there is no statewide VPP program like ConnectedSolutions. Instead, individual REPs (Retail Electric Providers) run their own VPP programs: Tesla Energy VPP pays market-based rates during grid emergencies, Rhythm Energy offers fixed monthly credits ($10-15/month), and new REP programs launch regularly. Average VPP revenue is $100-200/year in normal conditions, but ERCOT scarcity events (like Winter Storm Uri) can produce $500-2,000 in a single week. Texas is a high-variance VPP market.
Program details
Texas operates on the deregulated ERCOT grid, so residential battery VPP programs are run by individual REPs rather than by utilities. Tesla's Virtual Power Plant and Rhythm Energy both offer enrollment for qualifying batteries. Payment structures vary widely — use this as an indicative estimate.
ERCOT (the Texas grid operator) does not run a residential VPP directly. Instead, REPs aggregate residential batteries into virtual power plants and bid the combined capacity into ERCOT's ancillary services market. When wholesale prices spike ($1,000-9,000/MWh during scarcity events), REPs dispatch enrolled batteries and share the revenue with homeowners. Tesla Energy VPP is the largest program (~50,000 enrolled Powerwalls in TX). Rhythm Energy and Octopus Energy also offer VPP enrollment. Each REP has different terms, payout structures, and enrollment requirements. There is no single enrollment portal — you enroll through your chosen REP.
Real enrollment example
The Nguyens in Plano installed two Tesla Powerwall 3 units in March 2025. NuWatt helped them switch to a Tesla Energy REP plan and enrolled both batteries in the Tesla VPP the same week Oncor approved interconnection — about five weeks after install. From April through July, VPP dispatches were infrequent: a few small events netting $38 total. Then August hit. ERCOT called scarcity pricing on three consecutive afternoons as temperatures exceeded 107°F across the DFW metroplex. The Nguyens' two Powerwalls discharged at wholesale rates topping $5,000/MWh. Those three days alone earned $840. Full first-year VPP income: $1,190 — far above the $150 baseline NuWatt quoted, driven entirely by unpredictable ERCOT scarcity.
On a 108°F August Tuesday, ERCOT reserves drop below 3,000 MW at 2:50 PM. Tesla's VPP platform dispatches enrolled Powerwalls across North Texas. The Nguyens' two units begin exporting 10 kW combined within seconds. Inside, their two-story home stays at 73°F — the AC pulls from the grid while the batteries feed it. Wholesale prices spike to $4,200/MWh by 3:30 PM. The event stretches until 7:15 PM as demand holds into evening. By then, ERCOT scarcity pricing has been active for over four hours. The Powerwalls recharge overnight — but the Nguyens' solar array finishes the job by 11 AM the next morning, critical for the afternoon dispatch that follows.
ERCOT scarcity events are unpredictable and often cluster — two or three consecutive afternoons during heat waves. Solar recharging between events is critical in Texas because grid electricity during high-demand periods costs $0.15-0.25/kWh (and much more at wholesale). A 12 kW array in Plano produces 8-10 kWh between 9 AM and 2 PM, fully recharging a Powerwall before the next afternoon peak. Without solar, overnight grid charging at $0.12/kWh costs $1.60 per cycle — manageable — but misses the real risk: if ERCOT calls back-to-back scarcity days, a grid-only battery may not fully recharge in time. Solar guarantees the battery is full by early afternoon. Over a year, solar pairing adds $80-150 in avoided recharge costs and eliminates the risk of a half-charged battery missing a high-value scarcity event worth $200-400.

About REP Virtual Power Plant Programs

Methodology
VPP revenue estimates use published program rates from utility tariff filings and ConnectedSolutions program reports as of 2026. Actual payment depends on the number of events called, your battery’s performance during events, and ongoing enrollment. Rates change quarterly — re-run this calculator before making financial decisions. This is informational, not a guarantee of revenue.
NuWatt installs VPP-eligible batteries across all 9 service states. We handle the ConnectedSolutions / BYOD enrollment paperwork as part of the install.
Start my free battery quoteIt varies dramatically by REP and grid conditions. Tesla VPP pays market-based rates — $0 in normal conditions, potentially $50-200 per event during grid stress. In a normal year (no major scarcity), total VPP revenue is $100-200. But during scarcity events (Summer 2023 heat wave, Winter Storm Uri aftermath), enrolled batteries earned $500-2,000 in a single week. Rhythm Energy offers a more predictable $10-15/month (~$120-180/year). The calculator uses $150/year as the baseline — adjust up for high-volatility scenarios.
Tesla VPP requires a Powerwall and pays market rates — high ceiling ($2,000+ in scarcity), low floor ($100/year baseline). Best for risk-tolerant homeowners who want maximum upside. Rhythm Energy accepts any battery and pays fixed monthly credits ($10-15/month) — predictable but lower ceiling ($180/year max). Octopus Energy is entering the TX VPP market with a hybrid model. Our recommendation: if you install a Powerwall, enroll in Tesla VPP for the scarcity upside. For non-Tesla batteries, Rhythm provides reliable baseline income.
ERCOT uses scarcity pricing to balance supply and demand. When generation reserves drop below 3,000 MW, wholesale prices spike from $50/MWh to $5,000-9,000/MWh ($5-9/kWh). During these events, VPP-enrolled batteries discharge at the scarcity price. A 13.5 kWh battery discharging at $5/kWh earns $67.50 in a single hour. A 4-hour scarcity event = $270. These events are rare (5-15 hours per year) but they produce outsized returns. Texas had 47 scarcity hours in 2023 and 12 in 2024.
For Tesla VPP, you need to be on a Tesla Energy plan (they are a licensed TX REP). For Rhythm Energy VPP, you need to switch to a Rhythm plan. Other REPs have their own enrollment requirements. Switching REPs in Texas is easy (no fees, no contract break in most cases, takes 1-2 billing cycles). NuWatt helps match your battery choice to the best REP/VPP combination during the design phase.
Predictable income: ConnectedSolutions wins — $1,000-1,500/year guaranteed in MA/CT vs $100-200/year baseline in TX. Maximum upside: Texas wins — scarcity events can produce $500-2,000 in a single week, something impossible in regulated New England markets. Risk profile: ConnectedSolutions is a salary; Texas VPP is a commission. For financial planning, TX VPP revenue should be treated as a bonus, not a budgeted income stream.
No. VPP programs are run by REPs (retail providers), not TDSPs (transmission/distribution service providers like Oncor, CenterPoint, AEP). You choose your REP independently of your TDSP. All three TDSP territories participate in ERCOT equally. The only geographic factor is interconnection — your TDSP must approve battery interconnection before VPP enrollment, and timelines vary (Oncor: 4-6 weeks, CenterPoint: 6-8 weeks, AEP: 4-8 weeks).
