Frequently asked questions
Frequently asked questions about renewable energy contract calculator
PPAs typically run 10-25 years for utility-scale projects and 15-20 years for commercial solar. The long duration ensures the project can pay off its capital investment. Many PPAs include options to extend for additional 5-10 year periods.
An EPC (Engineering, Procurement, and Construction) contract covers the design, sourcing, and building of a renewable energy project. EPC timelines typically run 6-24 months depending on project size. They often include performance guarantees and liquidated damages for delays.
Operations & Maintenance (O&M) contracts should be reviewed 6-12 months before expiration. Compare current performance metrics, benchmark pricing against market rates, and assess whether to renew, renegotiate, or switch providers. O&M terms typically run 3-10 years.
Land leases for renewable energy projects typically run 25-35 years with renewal options. Rent escalation clauses (usually 1-3% annually or tied to CPI) significantly impact long-term project economics. Ensure your lease term exceeds your PPA term to avoid misalignment.
