Solar plus storage, Visayas, Philippines, 40 MW
Problem
build a development case for 40 MW of solar plus storage in the Visayas under a fixed offtake price.
Work
- sized generation and storage against a power purchase agreement price of 6.5 pesos per kilowatt hour, and modelled the resulting revenue picture.
6.5 pesos per kilowatt hourofftake price
the offtake price was fixed by contract, so the sizing question was how much storage that price could support, rather than what price the project needed to reach.
Consequence
the storage component was sized to the revenue the fixed price could carry, rather than to a target return set independently of the contract.
