A contract governing the sale of electricity between a generator and a buyer.
A PPA specifies how electricity or available capacity is measured and paid for. Some arrangements combine a capacity payment for making generation available with an energy payment for output delivered; others use different structures. Fuel-cost adjustments, availability standards, grid connection, payment security and termination terms can affect the final economics. A long contract may support financing while also committing the buyer to future costs.
Suppose a hypothetical generator delivers one million kilowatt-hours in a month under an energy-only PPA at J$15 per kilowatt-hour. The energy payment is J$15 million before any contractual adjustments. A separate capacity charge, fuel pass-through or performance deduction would change the invoice. This calculation is not a claim about a Jamaican project's tariff or a customer's retail electricity bill.
