Foresight Backs Mirai Power in German Storage Push

• Foresight backs Mirai Power’s German battery platform, betting on multi-revenue storage—frequency response, reserves, congestion relief, and shifting—powered by standardized design, smart aggregation, and disciplined dispatch.

Foresight, through a managed fund, has invested in Mirai Power, a German battery energy storage platform, as investor interest rises in “multi-revenue” flexibility assets. The deal reflects growing demand for storage that can provide services beyond simple energy arbitrage, including frequency response, reserves, congestion relief, and multi-hour shifting amid volatile power markets.

Mirai’s model focuses on standardizing battery designs, aggregating sites across multiple grid nodes, and using a unified optimization layer to rotate assets between market and ancillary-service offerings. Foresight is betting that Mirai’s operational strengths—EMS capabilities, dispatch discipline, and degradation management—plus fleet-level analytics, procurement, and O&M, will improve returns as Germany’s products and policies evolve.

How does Foresight’s Mirai investment advance multi-revenue battery storage beyond arbitrage?

• Moves storage from “buy-low/sell-high” into a broader participation stack by enabling batteries to earn revenue simultaneously (or sequentially) from energy and grid services, depending on system needs and price signals.
• Supports ancillary-service income streams (e.g., frequency containment/reserves) that respond quickly to grid events, helping smooth cashflows and reduce reliance on narrow spread economics.
• Creates a pathway for congestion-relief/locational value capture by aggregating assets across nodes so dispatch can target where constraints occur, not just when prices are high.
• Improves multi-hour shifting economics by pairing energy arbitrage windows with longer-duration dispatch rules that can be tuned as market design and remuneration evolve.
• Uses centralized fleet management and optimization to allocate limited battery power and capacity across competing revenue opportunities (so the portfolio is “rotated” rather than statically committed to one market).
• Emphasizes degradation-aware dispatch and asset health monitoring, which helps maintain usable life while still delivering high-frequency grid services—crucial for monetizing more than one product over time.
• Integrates strong EMS/controls and dispatch discipline to meet stringent performance requirements (accuracy, response times, availability), lowering the risk of service penalties and enabling more consistent reserve participation.
• Leverages aggregation and standardized engineering approaches to reduce per-site cost and operational variability, making it easier to scale multi-revenue operations as additional services are added.
• Strengthens the ability to procure, install, and operate batteries across multiple sites under a unified operating framework—supporting faster scaling and improved unit economics for “portfolio” revenues.
• Builds in performance analytics and benchmarking across the fleet, which helps refine bidding strategy, update operating constraints, and improve realized revenue versus modeled forecasts.
• Positions the investment to benefit from policy-driven market expansion in Germany and Europe, where storage remuneration increasingly depends on demonstrating capability across several grid services, not just energy shifting.
