Four paths exist for an SMB that wants to match its electricity consumption with renewable generation — ranked from simplest and cheapest to most involved. None of them require installing anything. The most common one takes effect on your next billing cycle.
Each path differs in commitment level, cost structure, and what “renewable” actually means on your bill. This guide covers the mechanics honestly, including what makes a green claim legitimate and what to ask before you sign anything.
Green supply plans are the simplest entry point. A competitive supplier sells you electricity and retires Renewable Energy Certificates (RECs) matching your usage — typically one REC per megawatt-hour consumed. The electrons flowing to your building are the same electrons that flow to every other customer on the grid; what changes is the accounting. RECs track and retire the environmental attributes of renewable generation so they can only be claimed once.
Green plans are available in every competitive electricity market we cover — Texas, Ohio, Pennsylvania, Massachusetts, New Jersey, and Washington DC. Enrollment works the same as any supply switch: you pick a plan, sign a contract, and the utility continues delivering power under its existing tariff.
The greenwash test: ask the supplier which RECs it retires, which registry tracks them, and whether they carry third-party certification such as Green-e Energy. Suppliers that can answer those questions clearly are backing the claim with real accounting. Suppliers that cannot are selling a label.
Renewable Energy Certificates can be purchased separately from electricity supply. A business on a standard (non-green) supply contract buys RECs from a broker or registry, retires them to match its annual consumption, and can make the same “100% renewable” claim as a green supply plan subscriber — because the accounting is identical.
RECs trade on open markets. Prices vary by renewable type, vintage year, and geography. RECs from projects in the same regional grid as your facility (in-region RECs) are generally worth more for sustainability reporting purposes than out-of-region RECs, and some corporate sustainability frameworks require them. Green-e certification sets a floor of quality standards for retail REC products.
Buying RECs separately makes sense when a business has already locked into a standard supply contract it cannot exit cheaply, or when it wants more control over which generation projects it supports. It separates the electricity purchase from the renewable attribute purchase entirely.
Community solar programs let a business subscribe to a share of a local solar project without installing anything on-site. The solar project generates power, that generation flows onto the grid, and the utility credits a portion of the project’s output against the subscriber’s bill. The credit appears on the utility delivery portion of the bill, not the supply portion — which means it reduces what you owe regardless of who supplies your electricity.
Community solar programs exist in Massachusetts, New Jersey, and Ohio. Availability depends on the utility territory and whether project capacity is open for new subscriptions. Programs typically offer bill credits at a rate tied to the project’s output and a fixed subscription term.
Community solar is the only path here that directly reduces delivery charges. A green supply plan and standalone RECs affect the supply side of the bill; community solar credits sit on the delivery side. That distinction matters for businesses trying to reduce total electricity costs, not just match supply with renewable accounting.
On-site solar — either owned outright or financed through a Power Purchase Agreement (PPA) with a solar developer — generates electricity at the facility itself. Consumption from on-site generation bypasses utility supply charges entirely for the portion it covers. Excess generation can often be exported to the grid under net metering rules, earning a credit against future bills.
On-site solar is a capital decision, not a rate decision. It suits businesses that own (or have a long lease on) a roof or land with adequate sun exposure, have stable enough operations to commit to a 15-to-25-year horizon, and have the appetite to evaluate a project on its own financial merits — installation costs, incentives, financing structure, and long-run avoided cost.
ElectricRates.org does not sell or install solar. We mention this path because it belongs in an honest comparison of what the options are. A business evaluating on-site solar should get quotes from licensed installers and independent financial analysis separate from any installer relationship.
| Option | How it works | Commitment level | Claim it supports |
|---|---|---|---|
| Green supply plan | Supplier retires RECs matching your usage each month | Supply contract term (1–3 yrs typical) | 100% renewable matched consumption |
| Standalone RECs | Buy and retire RECs separately from any electricity contract | Annual purchase, no long-term lock-in required | 100% renewable matched consumption |
| Community solar | Share of a local project; output credits your utility bill | Subscription term (varies by program) | Local solar generation; delivery bill reduction |
| On-site solar / PPA | Generation at the facility displaces grid supply directly | 15–25 years (ownership or PPA term) | Direct renewable generation on-site |
Green supply plans typically price at a modest premium over an equivalent standard fixed-rate plan from the same supplier, because RECs cost money. The premium is not fixed — it varies by supplier, market conditions, and the quality of RECs the supplier sources. Some suppliers use inexpensive out-of-region RECs; others source in-region or certified RECs that cost more and carry a stronger claim.
The right approach is to pull quotes for both green and standard plans at the same time, from multiple suppliers, and compare all-in rates. A green plan that quotes lower than a standard plan from a different supplier is not necessarily a bad deal — supply market pricing varies enough that the combination is possible. What you want to avoid is paying a premium for a green label backed by low-quality RECs with no certification.
Community solar economics depend on the gap between your subscription cost and the bill credit rate. Programs designed to benefit subscribers offer credits at or above subscription cost; read the subscription agreement before signing and confirm whether the credit rate is fixed or tied to a utility tariff that can change.
A legitimate 100% renewable claim requires that Renewable Energy Certificates (RECs) matching your annual consumption have been retired on your behalf. Each REC represents one megawatt-hour of verified renewable generation added to the grid. Without REC retirement, a "green" plan label is marketing — the electrons on the wire are the same regardless of what a supplier calls them. Ask your supplier which RECs it retires, from which projects, and whether they carry third-party certification such as Green-e.
Green supply plans typically price at a modest premium over an equivalent standard fixed-rate plan from the same supplier, because the supplier is buying or retiring RECs to back the claim. The gap varies by supplier, market, and the quality of the RECs used. The right approach is to compare all-in rates — green and standard — from multiple suppliers at the same time, the same way you would any commercial electricity quote. A higher rate is not automatically wrong; an unexplained rate jump without clear REC sourcing is.
A Renewable Energy Certificate represents the environmental attributes of one megawatt-hour of electricity generated from a qualifying renewable source — wind, solar, hydro, and others depending on the registry. RECs are tracked and retired through registries such as NEPOOL GIS (New England), PJM GATS (mid-Atlantic, Midwest), and ERCOT in Texas. When a supplier or business retires a REC, that environmental attribute is used up and cannot be claimed again. This accounting system is how a business in Ohio can legitimately claim its consumption is matched by wind generation from Kansas.
Community solar programs are available in several states including Massachusetts, New Jersey, and Ohio, and programs exist for both residential and commercial subscribers. A business subscribes to a share of a local solar project and receives a bill credit from the utility that offsets part of the delivery charge. Eligibility, credit rates, and subscription terms vary by program and utility territory. Contact your utility or a community solar aggregator to check availability at your service address.
No. Green supply plans — like any competitive supply plan — replace only the supply (generation) portion of your bill. Utility delivery charges, transmission fees, and demand charges remain set by your regulated utility tariff. Switching suppliers, green or otherwise, does not affect delivery costs.
