Energy Efficiency tenders — page 12
1,017 listings tracked right now · page 12 of 22
Programmes for industrial efficiency, building retrofits, heat recovery and demand reduction. Typical funders are UK DESNZ and the Industrial Energy Transformation Fund, the US DOE, EU LIFE and Horizon, and utility efficiency-obligation schemes. Listed below are the open energy efficiency 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 energy efficiency tenders and public contracts currently tracked by Raise Lens — 1,017 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 energy efficiency work rather than anything whose description happens to mention it.
The buyers publishing energy efficiency tenders and public contracts here include DLA TROOP SUPPORT, ESTADO DO CEARA, Kreisverwaltung des Eifelkreises Bitburg-Prüm, among 2 others. 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.
39 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.
