Negative-price exposure, curtailment, grid fees, support schemes — the framework behind Germany's battery and PV economics. The same rules that drive our PV-Watcher and BESS-Optimizer.
Germany couples PV feed-in funding to positive prices, exempts standalone storage from grid fees (for now), and runs redispatch + balancing/capacity products that batteries can serve.
Under the Solarspitzengesetz (in force 25 Feb 2025), new PV plants receive no EEG remuneration during hours of negative day-ahead prices; the unpaid energy is added back via extended funding. This is the §51-style exposure PV-Watcher tracks per plant.
Redispatch 2.0 governs grid-driven curtailment; curtailed renewable energy is generally compensated. New PV roof systems must be remotely controllable / capped (controllable from a threshold).
Standalone storage is exempt from grid charges (Netzentgelte) under §118 EnWG — a key BESS economics driver. The exemption is time-limited and politically reviewed; verify the current sunset date before modelling.
Day-ahead & intraday arbitrage (the Decke), plus FCR / aFRR / mFRR balancing and reactive-power products — all relevant to BESS-Optimizer revenue stacking.
