Soldera

Think Stripe for renewable energy certificates: plug in, automate the busywork, lift revenue, and slash the operational load by up to 95%. No software fees, ever. We earn only when your certificates sell. Today, thousands of renewable energy sites across Europe run with us.

For sellers, Soldera is the largest renewable energy certificate aggregator and private GO (Guarantees of Origin) auction host in the Baltics, managing GOs for thousands of production sites across Europe. Underneath all of this, we’re building a programmable settlement layer for EAC sellers and buyers, so deals clear faster, documents don't waste your time, and cash flows without friction.

Platform features include:

• Device registration and onboarding

• PPA allocation workflows

• Quality-label eligibility checks

• Consolidated reporting

• Automated invoicing

• AI-assisted contract processing

• Forward hedging and risk controls

For buyers and traders, that depth translates into direct, efficient access to a growing pool of GOs from our member producers. We aggregate across spot and forward, then auction large, diverse volumes with a simple buying process, predictable supply, and streamlined documentation for the unbundled EAC market.

We’re a Tartu, Estonia startup, founded by Stenver Jerkku and Al William Tammsaar.
