Virtual power plant – tie-in of PV plants with energy storage


As from 2016, the power from solar PV plants rated at 100 kWp and above has to be directly marketed. A chain store owner is considering expanding its PV solar capacity and tying in battery storage to raise power consumption coming from own production. It is being assisted in this by our customer, an energy supply utility. On the basis of its experience with pilot clients, Fichtner develops and evaluates a business model for direct marketing of PV power from plants of 100 kWp and up with integrated battery storage. For this purpose, Fichtner analyzes the structure for feeding residual power to the grid, determines the potential rev-enues from direct marketing, and checks options for utilizing battery storage. The client’s advantages from raising its own consumption are assessed against po-tential revenues in the frequency regulation market. The requirements and costs for technical plant tie-in into primary control power are reviewed. Fichtner creates a remuneration model for direct marketing of PV power with own consumption, with an assessment of the economic performance of battery storage.
