Buyers often search for renewable energy certificates or RECs when they need the broader family of energy attribute certificates. In GreenPowerHub, the buying workflow starts with the market, facility, country, volume, and certificate criteria rather than a separate REC checkout page. Use this page as the generic route to buy energy attribute certificates. If your need is North American REC-specific, use the RECs guide for terminology and market context, then return here when you are ready to choose a buying workflow.

Start by registering and adding the facility or country you need to cover, or review the buyer facility path first. From there, choose an available renewable energy option, request a price quote, or create an Open RFQ when you want supplier responses for a single-country need. What is an energy attribute certificate? An energy attribute certificate, or EAC, documents renewable electricity attributes separately from physical electricity. Examples include Guarantees of Origin, I-RECs, RECs, REGOs, and related certificate systems. Can I use this page to buy renewable energy certificates? Yes. Renewable energy certificates, or RECs, are part of the broader energy attribute certificate family. This page stays the generic buying route for EACs, including REC needs, while the RECs guide explains North American REC market terminology and context. Why does the facility step matter? Facility setup gives the workflow a country and annual electricity consumption volume. That context helps GreenPowerHub route buyers toward relevant options, quotes, or RFQs. ### Workflow questions What is the difference between Open RFQ and full RFQ? Open RFQ is a simpler route for a single-country request tied to facility or calculator context. Full RFQ is the advanced workflow for customizable scopes, selected participants, deadlines, and more complex sourcing requirements. Can I complete checkout immediately? Instant checkout is available where priced inventory exists. If price information is unavailable for the selected configuration, buyers can request a quote or use an RFQ route. Do full RFQ and Marketplace require subscription access? Full RFQ and Marketplace are advanced workflows. Buyers with simpler needs can start with facility setup and Open RFQ, then move to advanced access when they need custom participant control, firm market interest, or broader trading context. What documentation should I expect? Documentation depends on the market, delivery route, and supplier response. Buyers often evaluate cancellation, redemption, transfer, trade confirmation, and internal reporting needs before accepting an offer. Helpful resources ## Read more before choosing a route.
