Frequently asked questions
Frequently asked questions about power purchase agreement calculator
COD is when the power facility is fully operational and begins delivering electricity under the PPA. The contract term starts from COD, not signing date. Delays in achieving COD can trigger price adjustments, termination rights, or liquidated damages for the buyer.
PPAs typically include annual price escalators of 1-3% to account for inflation and rising costs. Some use fixed escalators (2% per year), others tie to inflation indexes (CPI), and some use tiered escalation (1% years 1-10, 2% years 11-20).
Early termination is difficult and expensive. Buyer termination for convenience typically requires paying a termination payment equal to the net present value of remaining contract payments (often millions). Seller default or force majeure may provide exit opportunities without penalties.
At contract expiration, the buyer typically has options: (1) extend the PPA at negotiated rates, (2) purchase the facility at fair market value, or (3) allow the contract to expire and source power elsewhere. Most buyers negotiate extension options upfront.
