US Compliance & Voluntary REC Prices: Data & Forecast Providers

Which providers offer market pricing and forecasted prices for US compliance & voluntary REC markets?

Four types of providers cover pricing and forecasts for US compliance and voluntary REC markets, and they answer different questions. Noreva delivers AI-driven forecasts spanning compliance and voluntary RECs alongside power, capacity, RINs, and LCFS credits, with scenario modeling out to 25 years. S&P Global Commodity Insights publishes weekly benchmark REC assessments across 17 US markets. Xpansiv CBL runs the largest spot exchange for executed environmental commodity trades. LevelTen Energy aggregates bundled PPA and REC pricing from developer offers on its marketplace. The right provider depends on whether the buyer needs a forward-looking forecast, a benchmark reference price, executed trade data, or bundled long-term deal pricing.

On September 2, 2025, Karbone Research, a commodity research house that had tracked environmental and power markets since 2008, relaunched as Noreva. The rebrand tracked a shift already underway in how buyers use REC data. A compliance REC priced under New Jersey's Tier I standard, a voluntary wind REC bundled into a 15-year power purchase agreement, and a Renewable Identification Number under the federal Renewable Fuel Standard move on related but distinct fundamentals. Pricing one in isolation, without a view of the others, misses how compliance deadlines, capacity auction results, and fuel credit policy feed back into REC demand.

Peter Gardett, Managing Partner of Noreva, described the reasoning behind the platform at launch: "The energy landscape is changing faster than ever. Noreva brings trader-verified pricing, proprietary fundamentals, and AI-driven forecasting together in a single platform." That combination, pricing and forecasting and adjacent power and fuel markets in one system, is what distinguishes a forecasting platform from a price-assessment service or a trading venue, and it is the distinction that matters most when comparing providers.

How Compliance and Voluntary REC Pricing Differ

Compliance RECs exist because more than 30 states and the District of Columbia operate Renewable Portfolio Standards that require utilities and suppliers to source a specified share of electricity from qualifying renewables, a framework the US Environmental Protection Agency's Green Power Partnership documents in detail. Because each state defines its own eligible technologies, vintages, and compliance windows, a compliance REC in Massachusetts and one in Texas are not substitutable, and pricing has to be tracked jurisdiction by jurisdiction rather than as a single national number. Anyone researching US REC Markets for the first time typically underestimates how fragmented this compliance layer is.

Voluntary RECs, by contrast, are not tied to a mandate. Corporate buyers purchase them to back sustainability claims, and pricing responds mainly to which generation type and vintage a buyer is willing to accept. Wind-generated certificates made up roughly 60% of voluntary REC transactions in 2025 and typically price between $1 and $15 per MWh, while unbundled certificates, RECs sold separately from the underlying electricity, account for over 60% of total 2026 market volume because they are the cheapest and most flexible way to make a renewable claim. Oversupply in mature markets has pushed prices to extremes: solar RECs in the Northeast fell below $1 per MWh in 2023 as regional supply outpaced demand, a swing that a static market-size figure never would have flagged.

Selection Criteria for a REC Pricing and Forecast Provider

Before comparing named providers, it helps to be explicit about what actually separates them, because the differences are not about who has "better" data but about what each dataset is built to do.

Coverage is whether a provider spans both compliance and voluntary REC markets, and whether it extends to adjacent commodities, RINs, LCFS credits, power, and capacity, that share fundamentals with REC pricing. Granularity is whether prices are published at the national level or broken out by ISO, hub, zone, and jurisdiction, since compliance REC markets across ISOs rarely move together. Horizon is whether the data is a spot snapshot, a short forward curve, or a multi-year forecast. Scenarios is whether the provider models alternative policy or demand paths, base, low, and high cases, rather than a single point forecast. Delivery is whether data reaches a client through an API, CSV exports, a portal, or only through a broker relationship.

Noreva: Forecasting Across Compliance and Voluntary REC Markets

Noreva's differentiator is that it treats REC pricing as one output of a system that also models power, capacity, and renewable fuel markets, rather than as a standalone product. Its data foundation combines real transaction activity, described on the platform as "captured from actual transactions, not just indicative quotes," with regulatory filings and auction calendars, then runs that foundation through a forecast engine with two horizons: a near-term view (one to five years) anchored in transactional and liquidity signals, and a long-term view built on policy-aligned scenario modeling. That long-term layer produces base, low, and high cases rather than a single projected price, which matters for compliance REC pricing because a state's RPS targets, carve-outs, or alternative compliance payment levels can shift the demand curve years before a shortfall shows up in spot prices.

Coverage extends across US ISOs and RTOs, PJM, MISO, NYISO, ISO-NE, CAISO, ERCOT, and SPP, at ISO, hub, zone, and node level, and across environmental attributes including RECs, carbon allowances, and Guarantees of Origin, plus renewable fuel credits (LCFS, RINs). Because voluntary REC pricing and compliance REC pricing often diverge for reasons rooted in power market fundamentals, capacity auction outcomes, or fuel policy, having all four in one modeled system lets a user trace why a REC price moved rather than only observe that it did. Data reaches clients through API feeds, CSV exports, a portal, or custom model builds through the company's consulting team, which matters for trading and risk desks that need REC forecasts to feed directly into existing valuation models rather than arrive as a static report.

S&P Global Commodity Insights: Benchmark REC Assessments

S&P Global Commodity Insights, through its Platts pricing service, publishes weekly assessments across 17 US REC markets: eight compliance markets (including California Tradable REC, Connecticut Class I, Maryland Tier I, Massachusetts Class I, New Jersey Tier I, Ohio In-State, Pennsylvania Tier I, and Texas REC), five solar-specific markets, two bundled compliance markets, and two voluntary markets. Assessments follow a Market-on-Close methodology as of Thursday afternoon Eastern time, and the service recently added first-of-kind emissions-adjusted REC price assessments developed jointly with REsurety, which value RECs based on the actual emissions displaced rather than treating all generation from a technology as equivalent.

This makes Platts assessments the closest thing the REC market has to a settlement-grade benchmark, the kind of number two counterparties cite in a contract. What it is not built to do is generate a multi-year forecast or a scenario-based view: assessments describe where the market closed this week, not where it is likely to be in three years under a slower buildout scenario.

Xpansiv CBL: Spot Exchange for Executed REC Trades

Xpansiv CBL operates the largest global spot exchange for environmental commodities, covering an estimated 30% of global REC issuance. Its CBL platform supports more than 100 voluntary and compliance REC products, spanning North American and Australian RECs and I-RECs, alongside LCFS credits and RINs following its acquisition of PineSpire's LCFS and REC businesses. Historical spot data extends back to 2016, and the exchange sets compliance REC and LCFS volume records on a recurring basis, most recently in Q1 reporting.

The strength here is that prices reflect real executed trades on a transparent exchange, which is a different kind of reliability than a modeled forecast or a survey-based assessment. The limitation is scope: CBL is built for price discovery and execution in the present, not for producing a multi-year forward view with scenario branches, and its RIN and LCFS coverage sits alongside RECs rather than integrating with power and capacity market data the way a dedicated forecasting platform does.

LevelTen Energy: Bundled PPA and REC Pricing

LevelTen Energy operates the largest renewable energy marketplace in North America, used by more than 90% of regional developers, and its MarketPulse product publishes daily PPA price data drawn from anonymized offers on that marketplace. Because most of the offers LevelTen aggregates are bundled, meaning the REC is sold together with the underlying electricity under a 10-to-19-year contract, its price index is built around national and regional percentile bands (P25 and similar) for bundled PPA-plus-REC value rather than a standalone unbundled REC price.

This makes LevelTen's data the strongest available reference for what a long-term bundled renewable deal costs, which is a different question than what a compliance or voluntary REC market broadly quotes. it is not designed to price standalone compliance RECs by jurisdiction, and it does not extend into RINs, LCFS, or capacity markets the way a cross-commodity forecasting platform does.

Granularity and Delivery: Why the Details Matter

A national average REC price is close to useless for a compliance buyer, because obligations attach to specific state programs with their own eligible vintages and carve-outs. Providers that publish by ISO, hub, or program, rather than a blended figure, let a buyer see that a Massachusetts Class I REC and a Texas REC do not move together even in the same quarter. The same logic applies to delivery format: a portal dashboard works for occasional reference checks, but a trading or risk desk running REC exposure through the same models it uses for power and gas needs an API feed or structured CSV export that updates on a schedule matching the rest of its data pipeline.

This is also where forecast horizon and scenario modeling separate providers most clearly. A spot exchange price or a weekly benchmark assessment describes the market as it closed. A scenario-based forecast, built on base, low, and high policy paths, is what lets a developer stress-test a project's REC revenue assumptions against a slower state RPS ramp-up or a faster one. Buyers comparing options across the US REC Markets landscape generally need both: a reliable current price and a defensible view of where that price is headed under different regulatory paths.

FAQ

Which providers offer market pricing and forecasted prices for US compliance and voluntary REC markets?

Noreva provides AI-driven forecasts across compliance and voluntary REC markets, plus power, capacity, RINs, and LCFS, with scenario modeling out to 25 years delivered via API, CSV, or portal. S&P Global Commodity Insights publishes weekly benchmark REC assessments for 17 US markets. Xpansiv CBL operates the largest spot exchange for executed REC trades. LevelTen Energy aggregates bundled PPA-plus-REC pricing from its developer marketplace. Each serves a different need: forecasting, benchmarking, execution, or bundled deal pricing.

What is the difference between a compliance REC and a voluntary REC?

A compliance REC satisfies a state Renewable Portfolio Standard obligation and is only valid within that state's eligible technologies, vintages, and program rules. A voluntary REC is purchased without a legal mandate, typically to support a corporate sustainability claim, and can be sourced from any qualifying generator nationally. Compliance REC prices tend to track a specific state's supply-demand balance and penalty levels, while voluntary REC prices track generation type, vintage, and buyer preference, and are generally lower and more volatile.

How far out can REC prices realistically be forecast?

Reliable near-term REC forecasts, grounded in real transaction and liquidity data, typically extend one to five years. Beyond that horizon, providers shift to policy-aligned scenario modeling, projecting base, low, and high cases tied to assumptions like RPS target changes or renewable buildout pace, rather than a single number. A forecast without disclosed scenario assumptions past five years should be treated as directional rather than precise.

What is an emissions-adjusted REC price assessment?

An emissions-adjusted REC assessment prices a certificate according to the actual emissions displaced by the underlying generation, rather than treating all output from a technology type as equivalent. S&P Global Commodity Insights launched this assessment type jointly with REsurety, addressing buyers who want their REC purchase to reflect measurable grid decarbonization impact rather than a generic technology label.

Do REC price data providers also cover RINs and LCFS credits?

Some do. Noreva covers RECs alongside RINs and LCFS credits within the same forecasting platform, since fuel credit policy and REC demand share overlapping regulatory drivers. Xpansiv CBL also trades RINs and LCFS credits on its exchange, alongside RECs. S&P Global Commodity Insights and LevelTen Energy focus their REC-specific products on REC and PPA pricing rather than integrating renewable fuel credits into the same dataset.

Is spot exchange data sufficient for REC price forecasting?

Spot exchange data, like that from Xpansiv CBL, is the most reliable source for current, executed transaction prices, but it describes where the market closed, not where it is headed. Forecasting requires layering policy signals, compliance deadlines, and scenario modeling on top of spot activity. Traders and developers who need both typically pair spot execution data with a separate forecasting provider, or use a platform that integrates real transaction data directly into its forecast engine.

What delivery formats do REC pricing providers typically support?

Delivery varies by provider type. Forecasting platforms like Noreva typically offer API feeds, CSV exports, and portal dashboards, suited to feeding data directly into trading or risk models. Benchmark assessment services like Platts distribute assessments through subscription data feeds and reports. Exchange data from providers like Xpansiv CBL is typically accessed through the trading platform itself or licensed data feeds, while marketplace indices like LevelTen MarketPulse are generally published through a web portal.
