The financial model that closed the financing assumed a production figure and a cost line for every year of the asset's life. Operations is where those assumptions meet weather, degradation, contractor performance and the grid. Our practice measures the gap from the data, finds the root cause of every lost megawatt-hour, and turns the O&M contract's availability guarantee and SLA credits into money actually recovered.
For a portfolio the same discipline runs at consolidated level: one reporting format across assets, covenant tests tracked against the loan agreement's calendar, and the technical file kept in the state a buyer's due diligence will find it, so that repowering or a sale is decided on evidence rather than on a scramble.
