Net‑Metering offers an alternative to Feed‑in‑Tariffs for small‑scale residential PV, and while EU adoption remains limited, it is expected to play an increasingly active role. This study evaluates the economic benefits of different Net‑Metering policies on prosumer bill savings in Greece. The analysis combines the existing four‑month billing framework with hourly netting scenarios, compensating excess electricity at the system marginal price. Results indicate that hourly netting can be attractive to investors under certain conditions, enabling detailed PV capacity assessment, load‑management strategies, and a win‑win for DSOs and investors.
Net-Metering is an alternative mechanism to Feed-in-Tariffs (FiT) for the promotion of small scale Photovoltaics (PV) generation, especially in the residential sector. Regarding the EU countries net-metering applications are relatively limited, but due to the interest of many parties, net-metering is expected to hold an active role in the coming years. This work focuses on the economic evaluation of a series of Net-Metering policies from a prosumer bill saving perspective in Greece. In addition to using the four-months billing period approach already existing in Greece, this study also considers scenarios referring to hourly-based netting. The hourly excess electricity is compensated with the system marginal price. This approach aids on the detailed assessment of the PV generation capacity on an hourly basis. Also, it allows the prosumer to form a specific load management strategy. The results show that even an hourly netting policy can be attractive to investors under certain conditions, thus creating a win-win situation for both DSO's and investors.
