Met-Ed (FirstEnergy) serves eastern Pennsylvania with a flat $0.19/kWh rate and no time-of-use option. That means zero battery arbitrage revenue — a fundamentally different equation than PECO or PPL. Here is what actually works for solar + battery in Reading, Allentown, and the Lehigh Valley.

Solar: Yes, absolutely. Met-Ed net metering credits your excess solar at the full $0.19/kWh retail rate, making solar panels financially strong even without TOU. A 10 kW system saves approximately $2,185/year through net metering alone, plus $242-420/year in SRECs.
Battery: Mostly no, financially. Without a TOU spread, a battery generates only $50-150/year in self-consumption value on a flat rate. At $12,500-$15,000 installed, the payback exceeds 80 years. The only strong case for a battery on Met-Ed is backup power during outages or positioning for future demand response programs.
Bottom line: Invest in solar panels, skip the battery unless you need backup power. Put the $13,000+ battery budget toward a larger solar array instead.
Met-Ed (Metropolitan Edison) is a FirstEnergy subsidiary serving approximately 570,000 customers across eastern Pennsylvania. Unlike PECO which serves the dense Philadelphia metro, Met-Ed covers a mix of suburban, small-city, and rural areas — ideal for solar due to less shading and larger roof areas.
Met-Ed residential customers are billed under Rate RS (Residential Service) — a flat per-kWh charge with no time-of-use differentiation. This has major implications for battery storage economics.
Rate Structure
Flat — same rate 24/7/365
No seasonal variation, no peak windows
Pennsylvania is a competitive choice state. You can shop for an alternative electricity supplier for the generation portion of your bill. However, third-party residential TOU rates are extremely rare. The distribution charge (Met-Ed) remains flat regardless of your supplier choice. Monitor papowerswitch.com for any future TOU offerings in the Met-Ed territory.
Most solar battery guides assume TOU arbitrage as the primary value driver. That does not apply here. Let us be transparent about what a battery is actually worth on Met-Ed flat rate pricing.
Met-Ed has no TOU rate — zero arbitrage revenue
Avoided outage costs (food spoilage, hotel, lost work). Value depends on outage frequency.
Store excess daytime solar for evening use. Marginal on flat rate since net metering already credits at $0.19/kWh.
PA PUC considering residential demand charges. Battery owners would be positioned to benefit.
FirstEnergy may launch battery demand response under Act 129 Phase V. Not yet available.
A Tesla Powerwall 3 costs $12,500-$15,000 installed. On Met-Ed flat rate, the measurable financial benefit is approximately $100-150/year from self-consumption optimization. That is an 83-150 year payback — well beyond the battery warranty (10 years) and expected lifespan (15 years).
Compare to PECO territory where the same battery earns $550-720/year in TOU arbitrage alone, achieving payback in 17-27 years. The difference is entirely due to PECO having a TOU rate and Met-Ed not having one.
Even without financial arbitrage, there are legitimate reasons to add battery storage in Met-Ed territory. These are non-financial or forward-looking value propositions.
Met-Ed territory, especially the rural and semi-rural areas of Berks, Carbon, and Monroe counties, experiences more frequent power outages than the Philadelphia metro. A Powerwall 3 provides 12-18 hours of whole-home backup.
The PA utility landscape is evolving. Having a battery installed now positions you for future value streams that may emerge.
| Size | Model | Cost | Backup | Verdict |
|---|---|---|---|---|
| 5 kWh | Enphase IQ 5P | $5,500-$7,000 | 4-6 hrs (essentials) | Backup only — not financially justified |
| 10 kWh | Enphase IQ 10T | $10,000-$13,000 | 8-12 hrs (essentials) | Extended backup — poor financial return |
| 13.5 kWh | Tesla Powerwall 3 | $12,500-$15,000 | 12-18 hrs (whole home) | Best backup per dollar — still long payback |
Without TOU arbitrage, net metering at $0.19/kWh becomes the dominant financial return for Met-Ed solar customers. Understanding the rules maximizes your savings.

If your system produces more than you consume in a year, Met-Ed pays out excess credits at the price-to-compare rate — roughly $0.07-$0.09/kWh. That is less than half the retail rate.
Design tip: Size your system to match 90-95% of annual consumption. Slight underproduction ensures all credits are consumed at the full $0.19/kWh value rather than cashed out at $0.07-$0.09/kWh.
Without battery arbitrage revenue, SRECs become a more significant percentage of your total solar return in Met-Ed territory. PA SRECs trade at $22-35/SREC on the PJM-GATS market. While modest compared to NJ or MA, they add meaningful income over 15+ years.

PRESS Act watch: The PA Renewable Energy Standard Strengthening (PRESS) Act would raise the solar carve-out from 0.5% to 5.5%, which could push SREC prices to $100+ range. For Met-Ed customers without TOU battery revenue, this legislation could significantly accelerate solar payback. The bill is currently pending in the PA legislature.

Requires $12,500-$15,000 battery investment
SRECs generate 2-4x the annual value of a battery on Met-Ed flat rate — and require zero additional equipment investment. This is why solar panels (not batteries) should be the priority for Met-Ed customers.
Section 25D (the residential solar ITC) expired December 31, 2025. Homeowners can no longer claim the 30% credit on a cash purchase. But Section 48/48E remains available for third-party-owned (TPO) systems — leases and PPAs — where the financing company claims the ITC and passes savings to you as a lower monthly rate.
Why TPO matters more for Met-Ed: Without TOU arbitrage to accelerate payback, a cash purchase takes longer to pay off. A TPO/lease provides day-one savings with no upfront cost, which can be more attractive for Met-Ed customers than for PECO customers who have TOU arbitrage to offset the higher upfront investment.
This comparison shows exactly how much battery arbitrage revenue Met-Ed customers miss compared to PECO, PPL, and Duquesne Light customers. The gap is significant.
| Utility | TOU? | Summer Spread | Winter Spread | Annual Arbitrage |
|---|---|---|---|---|
| PECOPhiladelphia metro | $0.19/kWh | $0.12/kWh | $550-720 | |
| PPLCentral & NE PA | $0.12/kWh | $0.08/kWh | $280-380 | |
| Duquesne LightPittsburgh metro | $0.10/kWh | $0.06/kWh | $180-260 | |
| Met-EdReading, Lehigh Valley | N/A (flat) | N/A (flat) | $0 |
Over 15 years (typical battery extended life), a PECO customer earns $8,250-$10,800 in TOU arbitrage from the same battery that earns $0 in Met-Ed territory. This gap alone accounts for the entire cost of the battery in PECO territory.
Rather than spending $13,000+ on a battery with poor returns, Met-Ed customers should consider: (1) a larger solar array to maximize net metering, (2) an EV charger to consume more solar directly, or (3) a heat pump to electrify heating and increase solar self-consumption.
This is the core financial analysis for Met-Ed territory. On flat rate pricing, adding a battery significantly extends payback with minimal additional annual value.
With 2% annual rate escalation, effective payback drops 2-3 years. No Section 25D ITC (expired).
Battery adds $14,575 to cost but only $125/yr in value. The battery alone has a 117-year payback.

Met-Ed uses the FirstEnergy interconnection process, which tends to take longer than PECO. Plan for 5-7 weeks total from application to Permission to Operate (PTO).
File interconnection application through the FirstEnergy portal with system design, single-line diagram, and equipment specifications. Met-Ed uses the same FirstEnergy interconnection process as Penn Power and Penelec.
Met-Ed reviews system design for code compliance and grid compatibility. FirstEnergy territories tend to take longer than PECO for engineering review. Battery systems may add 1-2 extra weeks.
Install solar + battery system. Schedule municipal electrical inspection. Met-Ed requires passing inspection and a copy of the inspection certificate before proceeding.
Met-Ed installs bidirectional net meter. Permission to Operate (PTO) issued. FirstEnergy meter swaps historically take longer than PECO — plan for 2-4 weeks after inspection.
FirstEnergy vs. PECO interconnection: Met-Ed (FirstEnergy) interconnection typically takes 2-3 weeks longer than PECO. Engineering review and meter swap timelines are the main delays. If battery storage is included, add an extra 1-2 weeks for the additional review. Plan for 5-7 weeks total.
No. Met-Ed (FirstEnergy) does not offer a residential TOU rate. All residential customers are billed at a flat rate of approximately $0.19/kWh under Rate RS. This means there is no peak/off-peak spread for battery arbitrage. Unlike PECO (which has Rate R-TOU with a $0.19/kWh summer spread), Met-Ed customers cannot earn TOU arbitrage revenue from a battery.
Honestly, a battery is hard to justify financially on Met-Ed flat rate pricing. Without TOU arbitrage, the only monetary value a battery provides is marginal self-consumption optimization ($50-150/year). At $12,500-$15,000 for a Tesla Powerwall 3, the financial payback exceeds 80 years. The primary value is backup power during outages — if your area experiences frequent power outages, or you have medical equipment requiring uninterrupted power, a battery has real non-financial value.
Met-Ed provides 1:1 retail net metering at approximately $0.19/kWh for residential systems up to 50 kW. Excess generation is credited at the full retail rate and carries forward month-to-month. At the end of your annual billing period, any remaining credits are paid out at the price-to-compare rate (the generation portion only, approximately $0.07-$0.09/kWh). This makes sizing your system to match annual consumption critical.
PA SRECs trade at $22-35 each on the PJM-GATS market (1 SREC = 1,000 kWh of production). A typical 10 kW system in Met-Ed territory produces approximately 11,500 kWh/year, generating about 11-12 SRECs worth $242-420/year. PA SREC prices are low due to the weak 0.5% solar carve-out in the AEPS. The PRESS Act, if passed, would raise this to 5.5% and significantly boost SREC values.
Pennsylvania is a competitive choice state, meaning you can choose an alternative electricity supplier. However, TOU rates from third-party suppliers are rare for residential customers. The supply portion of your bill could be competitive-shopped, but the distribution portion (Met-Ed) remains flat. Even with a competitive supplier, the arbitrage opportunity is limited because the distribution charge (roughly 40% of your bill) stays flat regardless.
Solar in Met-Ed territory (Reading, Allentown, Lehigh Valley) costs approximately $3.15-$3.45/W before any incentives. A typical 10 kW system runs $31,500-$34,500 plus 6% PA sales tax ($1,890-$2,070). With no Section 25D residential ITC (expired December 2025) and no PA state credit, this is the full out-of-pocket cost for a cash purchase. TPO/lease options through Section 48/48E can reduce effective costs.
Met-Ed does not currently have a residential battery demand response program. FirstEnergy is exploring grid modernization under Act 129, but no formal residential DR program has been announced for Met-Ed territory. Battery owners should monitor FirstEnergy regulatory filings for future program developments.
Met-Ed territory averages approximately 1,150 kWh/kW/year in solar production, which is slightly below PECO territory (1,250 kWh/kW/year) due to the more inland location. A 10 kW system produces roughly 11,500 kWh/year. The Reading and Allentown areas receive approximately 4.3-4.6 peak sun hours per day annually.
Yes — solar without a battery is the recommended approach for most Met-Ed customers. Net metering at $0.19/kWh provides the primary financial return, and SRECs add $242-420/year. Without TOU arbitrage to justify battery costs, the additional $12,500-$15,000 for a battery adds years to your payback with minimal financial return. The exception is if you have frequent outages or critical backup needs.
