I am working on a project in Sweden that purchases green energy from a wind farm in Norway to cover the consumption of the entire company's operations. I have obtained certificates of the amount of purchased energy for the last few years, proof that the contract is renewed on an annual basis, and proof that the company in Norway is not legally allowed to sell the same energy to more than 1 customer (of course).

In addition to providing proof that an adequate amount of green energy is purchased to account for the additional energy consumption arising due to this added new building [or 35% thereof], is there more evidence I would need to provide in order to demonstrate compliance?
