Vena Energy has secured a 46.8 MW battery storage project in Japan's FY2025 Long-Term Decarbonised Power Source Auction (LTDA), run by OCCTO. The NRE Nakagawa 2 project will be located near Matsumoto City in Nagano Prefecture, adding to Vena's growing storage portfolio in Japan. The LTDA scheme provides long-term revenue certainty to support investment in clean power assets, helping Japan move toward its 2050 carbon neutrality target. Battery storage is critical for managing renewable intermittency and strengthening grid resilience. This award follows Vena's Hikone storage project which started commercial operations last year. The company says it will keep engaging with local communities during development. The LTDA mechanism appears to be working as intended, offering a stable revenue pathway for storage developers and supporting the broader shift to low-carbon power in Japan.

46.8 MW is a decent chunk for a single battery project. The LTDA auction gives long-term revenue certainty, which is key for storage. Would be interesting to see the duration, the article didn't specify MWh. Also, how does this fit with OCCTO's grid planning? Still, good to see storage getting capacity payments.

The LTDA scheme is a solid policy tool. It provides revenue certainty for storage which is often hard to finance. But the details matter: how are the capacity payments structured? Are they based on availability or dispatch? That will determine if it actually helps decarbonization or just adds idle capacity.

Vena Energy building out its storage portfolio in Japan. The Hikone project started last year, now this. Good sign that the market is moving. Long-term revenue certainty from auctions is what makes these projects bankable. Also, location near Matsumoto should help with local grid congestion.

Battery storage is essential for dealing with solar variability. Japan has been adding a lot of solar, so this is timely. 46.8 MW helps, but we need much more to balance the grid. Good to see the auction mechanism working.
