Tokyo — As Japan accelerates its transition from a fixed-price system to market-linked energy, grid-scale battery energy storage systems (BESS), whether standalone or co-located with solar photovoltaic (PV) systems, are steadily increasing, creating diverse investment opportunities in a rapidly growing market.
Second Foundation, a global leader in algorithmic power trading and flexibility asset management, and its local partner, IQg Inc., successfully concluded a seminar series aimed at addressing "price volatility," a significant industry challenge.
The three-part session was attended by 50 asset owners and developers. Participants actively exchanged opinions with the goal of finding optimal methods for integrating BESS as solar power plants transition from the Feed-in Tariff (FIT) to the Feed-in Premium (FIP) system. A central theme of the discussions was Second Foundation's advanced analytical insights into the economic viability of various options, considering PV installation locations, currently applicable commercial schemes (FIT, FIP, etc.), and the potential for future BESS integration.
Furthermore, Second Foundation introduced a new "BESS and PV+BESS Tolling Scheme" for the Japanese market. Under this scheme, Second Foundation acts as an off-taker, assuming the revenue from BESS assets and providing asset owners with a fixed income. Second Foundation has been operating BESS tolling services in the European market since 2024.
Redefining Risk in Renewable Energy
In an era of fluctuating energy prices, Second Foundation leverages its trading expertise cultivated in the European market to provide a "safety net" for its Japanese partners. The new tolling scheme enables asset owners to:
Minimize Market Exposure: Transfer the complexities of day-ahead trading and price volatility risks to Second Foundation's trading book.
Optimize FIT to FIP Transition: Integrate BESS with PV assets to capture peak prices and secure BESS revenue, expanding revenue streams.
Ensure Bankability: Provide stable and predictable cash flows, making large-scale battery storage projects more attractive to investors.
