Frequently Asked Questions

Who buys green tenders?

State utilities, national energy and water regulators, multilateral development banks, climate funds, and municipalities. Increasingly, private off-takers procure via public PPA frameworks.

How do grants differ from tenders in this space?

Grants typically fund feasibility, pilots, capacity building and TA — issued by climate funds, bilateral agencies and foundations. Tenders fund construction, equipment supply and O&M.

What compliance do green tenders require?

IFC Performance Standards, environmental and social safeguards, increasingly EU Taxonomy alignment for European-funded work, and local-content commitments.
