For a project to earn EA Credit Renewable Energy Production from a PV array and wind turbine owned by a third party, what must be true?

To earn the EA Credit Renewable Energy Production from a PV array and wind turbine owned by a third party, the requirement of having a purchase agreement lasting at least 10 years is crucial. This long-term purchase agreement ensures that the project has a reliable and continuous supply of renewable energy, which contributes to the project's sustainability goals.

The importance of such an agreement lies in its ability to demonstrate the project's commitment to renewable energy use over a significant duration, thereby enhancing the credibility of the energy claims. A well-defined contract also ensures that the energy produced can be counted towards the project's renewable energy credits, reinforcing the sustainability measures the project intends to implement.

In contrast, the other options do not meet the necessary requirements for this particular credit. The generation of energy during peak hours, the installation of an energy storage system, and the operation of the renewable source by the project owner are not stipulations for acquiring the credit in question. Therefore, the long-term purchase agreement is the correct and essential requirement for the project's eligibility under this credit.
