Renewable Energy tenders — page 3
304 listings tracked right now · page 3 of 7
Renewable energy is the largest sustainability sector by funding volume, most public-sector climate spend flows here, directly (CfD auctions, IRA tax credits, EU Innovation Fund) or indirectly (grid, storage, transmission). For founders, the non-dilutive opportunities cluster in earlier-stage tech (next-gen PV, floating offshore, enhanced geothermal, perovskites) and in deployment-support for harder-to-finance projects. Listed below are the open renewable energy tenders and contract notices that landscape produces, taken from each buyer's own notice and re-checked on every refresh.
Energy procurement mostly runs through utilities, transmission and distribution operators, and public bodies buying on behalf of a network. Expect framework agreements rather than one-off purchases, a prequalification stage before the tender proper, and multi-year terms with performance obligations attached. Consortium bidding is normal, and the technical annexes usually carry more weight in scoring than the price envelope does.
This page lists open renewable energy tenders and public contracts currently tracked by Raise Lens — 304 of them right now, sorted with the soonest deadline first. Every listing has been classified against the sustainability taxonomy rather than matched on keywords, so what appears here is renewable energy work rather than anything whose description happens to mention it.
42 distinct buyers are publishing the renewable energy tenders and public contracts on this page. Who is funding matters as much as what: eligibility, reporting burden and the realistic timeline to a decision vary far more between buyers than between individual calls, which is why the listing names the buyer on every opportunity it opens.
Geographic coverage on this page spans SUBSAHARAN-AFRICA, AFRICA, MENA. Eligibility is usually tied to where the work happens or where the applying organisation is registered, and the two are not always the same — worth checking before investing time in an application.
48 of these close within the next 30 days. Deadlines are taken from the source listing and re-checked on every refresh, but the originating buyer remains the authority — always confirm against the official notice before you submit.
