Performance guarantees and performance liquidated damages (PLDs) are an essential element of most engineering, procurement, and construction (EPC) contracts, especially those related to solar and biogas projects; they make guaranteed levels of project performance, quality, and output enforceable. Specifically, PLDs compensate project owners for financial losses (or a reasonable approximation of them) incurred when projects fail to meet performance guarantees. Appropriately structuring PLDs in EPC contracts requires protecting project owners while balancing the risks for contractors, whose costs will often increase commensurate with increased contract risk. Ultimately, well-structured PLDs protect project owners, allocate appropriate risk to EPC contractors, and reassure financing parties that projects will perform as anticipated.
