Renewable energy certificates
How to Generate I-RECs for Solar Projects
Solar developers can create an additional environmental-attribute revenue stream by registering eligible facilities, documenting ownership, verifying metered generation and requesting certificate issuance.
Generating solar electricity does not automatically generate tradable I-RECs. A project must be accepted under the applicable market rules, its production facility must be registered and each issuance request must be supported by verified generation data.
The electricity product is formally known as an I-REC(E). Under the I-TRACK Product Code for Electricity, each certificate represents the environmental attributes of one megawatt-hour of electricity. The record identifies characteristics such as the production facility, location, technology and generation period, allowing a buyer to make a documented renewable electricity claim.
The essential sequence:
confirm country eligibility, establish ownership of the environmental attributes, register the solar facility, collect acceptable meter evidence, submit an issuance request and transfer or redeem the resulting certificates through the registry.
What an I-REC(E) is and is not
It is an energy attribute certificate
One I-REC(E) records the attributes associated with one MWh of eligible electricity generation.
It is separate from the electricity
The certificate can generally be transferred independently from the physical power, subject to local rules and contracts.
It supports electricity claims
After redemption, the certificate can support a beneficiary's renewable electricity and Scope 2 reporting.
It is not a carbon offset
An I-REC(E) does not represent one tonne of avoided or removed emissions and should not be marketed as a carbon credit.
Developers should identify precisely which rights they are selling. A power purchase agreement may already transfer environmental attributes to the offtaker. A project may also participate in a domestic renewable certificate, subsidy or carbon-credit program. Those arrangements must be reviewed before registration to prevent duplicate issuance or conflicting claims.
Who participates in the issuance process
| Party |
Primary role |
Project-level responsibility |
| I-TRACK Foundation |
Maintains the international tracking standard and accredits product codes and issuers |
Provides the rules governing registration, issuance, transfer and redemption |
| Accredited Issuer |
Administers the code in an authorized country or region |
Registers facilities, checks evidence and approves eligible issuance requests |
| Registrant |
Represents the owner or its authorized agent |
Registers the production facility and submits meter-backed issuance requests |
| Participant |
Holds a registry account |
Receives, transfers and redeems certificates; the Registrant may also be a Participant |
| Buyer or beneficiary |
Purchases the renewable attributes |
Uses redeemed certificates for the relevant reporting period and consumption claim |
An authorized Issuer must be active in the project's country before certificates can be created. Developers can check the I-TRACK market map
to identify the relevant Issuer and confirm whether the market is open. National regulations and Issuer procedures can add requirements beyond the general product code.
How to generate I-RECs step by step
Step 1
Confirm that the country and facility are eligible
Contact the local Issuer before assuming the project qualifies. Confirm technology eligibility, commissioning-date rules, interaction with national certificate schemes, acceptable meters, issuance deadlines and whether self-consumed or behind-the-meter output can be included.
Step 2
Establish ownership of the environmental attributes
Review the PPA, concession, site lease, interconnection agreement, EPC documents and any government incentive. The applicant must have an unambiguous legal right to register and sell the attributes. If an agent will act as Registrant, document the owner's authorization.
Step 3
Choose the account structure
Decide whether the project owner will become both Registrant and Participant or appoint specialist service providers. A Registrant handles facility registration and issue requests. A Participant account is needed to receive, transfer and redeem certificates in the registry.
Step 4
Register the solar production facility
Submit the Issuer's application with corporate KYC, ownership or authorization records, facility coordinates, installed capacity, technology, commissioning date, grid connection, meter details and supporting licenses. The Issuer may request clarifications, independent verification or a site inspection.
Step 5
Build an auditable metering process
Map the revenue meter, backup meters, data owner and reporting frequency. Reconcile the plant's records with utility or grid statements and preserve the underlying evidence. Issuance is based on eligible measured production, not the project's nameplate capacity or financial-model forecast.
Step 6
Submit the issuance request
After electricity has been generated, the Registrant submits the eligible MWh for the relevant production period and uploads the evidence required by the Issuer. The Issuer reviews the data, resolves discrepancies and approves or rejects the request under the local code.
Step 7
Receive and commercialize the certificates
Approved I-REC(E)s are issued into the nominated Participant account. The owner can sell certificates through spot transactions, a forward offtake, a portfolio arrangement or a bundled electricity contract. Pricing varies by country, technology, vintage, facility characteristics and buyer demand.
Step 8
Transfer and redeem for the end user
Certificates may move between Participant accounts before the final holder redeems them for a named beneficiary and reporting purpose. Redemption permanently allocates the certificates so the same units cannot be resold. Evident's electricity registry overview
explains these operational roles.
Documents a solar developer should prepare
| Document group |
Typical evidence |
Why it matters |
| Corporate and KYC |
Registration records, ownership chart, authorized signatories and identification |
Confirms the legal entity and controlling parties |
| Ownership and authority |
Asset ownership, lease, concession, board approval and agent authorization |
Demonstrates the right to register the facility |
| Technical facility data |
Single-line diagram, capacity, module technology, coordinates and commissioning date |
Defines the registered production device and its characteristics |
| Grid and licensing |
Generation license, interconnection agreement and utility confirmation |
Supports legal operation and the delivery configuration |
| Metering and generation |
Meter serials, calibration records, readings, invoices and grid statements |
Supports the quantity requested for issuance |
| Attribute rights |
PPA clauses, incentive documents and declarations covering other REC or carbon programs |
Reduces the risk of double issuance, sale or claim |
The exact list depends on the country and Issuer. Starting this work during development, rather than after months of operation, makes it easier to align contracts and metering with the certificate rules.
How many I-RECs can a solar project generate?
Illustrative calculation
A 100 MW solar plant at a 22% capacity factor
100 MW × 8,760 hours × 22% = 192,720 MWh of estimated annual generation.
If all of that output is eligible and accepted by the Issuer, the project could generate up to 192,720 I-REC(E)s for that year. Actual issuance will follow verified eligible production at the approved meter and may differ because of degradation, outages, curtailment, auxiliary consumption, meter adjustments and local rules.
This distinction matters in project finance. Forecast I-REC revenue should be modeled using conservative generation, realistic eligibility and an achievable certificate price. It should not be treated as guaranteed contracted income unless a creditworthy buyer has signed an enforceable offtake with clear volume and price terms.
Costs and ways to sell I-RECs
There is no universal registration cost or certificate price. Depending on the market, a project may incur facility-registration, issuance, Participant, transfer, verification and redemption charges. Commercial value can vary materially between countries and vintages, so developers should obtain a current fee schedule and buyer indications before relying on a revenue forecast.
Spot sale
Sell issued certificates at the available market price. This offers flexibility but leaves the project exposed to price and liquidity risk.
Forward offtake
Contract future eligible production with a buyer. The contract can improve revenue visibility, although issuance still occurs only after generation.
Bundled PPA
Sell electricity and its environmental attributes together. The contract must state who owns, registers and redeems the certificates.
Portfolio aggregation
Combine output from several eligible plants to offer buyers greater scale, consistent documentation and diversified generation.
A developer seeking capital against expected certificate cash flows can explore pre-financing future RECs. This is a contractual financing or forward-sale structure. It does not create certificates before the underlying electricity has been generated and verified.
Common mistakes that delay issuance
Avoidable risks
Registration should be designed into the project
Common problems include discovering that no authorized Issuer is active in the country, overlooking a PPA clause that assigns the attributes to the offtaker, relying on incomplete meter records, missing vintage deadlines, entering inconsistent facility data and attempting to register output already claimed under another system.
Developers also lose credibility when they describe I-REC(E)s as carbon offsets or market forecast generation as already issued inventory. Clear terminology, traceable evidence and accurate registry status are essential when approaching corporate buyers or financiers.
For projects that still need construction or refinancing capital, certificate revenue should sit within the wider funding strategy. Financely's solar project financing advisory and placement service

Frequently asked questions
How many I-RECs are issued per MWh?
One I-REC(E) represents the attributes of one eligible, verified MWh of electricity. A project's issued volume depends on the production accepted by the relevant Issuer.
Can future I-RECs be issued before the solar power is generated?
No. Certificates are issued against verified production. A developer may contract or finance expected future output, but the underlying I-REC(E)s are created only after eligible generation and an approved issuance request.
Are I-RECs the same as carbon credits?
No. I-REC(E)s document renewable electricity attributes in MWh. Carbon credits represent a quantified tonne of greenhouse-gas reduction or removal under a separate methodology and registry.
Can rooftop or behind-the-meter solar generate I-RECs?
It may qualify, but eligibility depends on the country, local Issuer rules, meter configuration and ownership of the attributes. Confirm the requirements before promising certificates to a buyer.
Does Financely issue or verify I-RECs?
No. Financely is not an Issuer, registry operator or verifier. It can help qualified developers organize documentation, coordinate specialist providers, plan commercialization and structure project financing on a best-efforts basis.
