Tensor Cloud Energy AI for Renewable and Battery Aggregation

Tensor Energy is a Fukuoka-based energy software company founded in November 2021 to build an operating system for distributed renewable energy. It serves solar and battery owners in Japan who must forecast, bid and balance their output under the feed-in premium system and new storage markets.

Tensor Cloud combines AI solar generation forecasts, price forecasts for the JEPX spot and balancing markets, cross-market optimisation every 30 minutes, automated bidding and OCCTO plan submission, and real-time battery charge and discharge control. It also covers financial modelling, reporting and anomaly detection. Operators can run the platform themselves as SaaS or hand dispatch to Tensor Aggregation, where Tensor acts as aggregator and generally carries imbalance risk.

• AI generation forecasts: per-plant solar models updated in real time.
• Price forecasts: JEPX spot and balancing-market prices up to seven days ahead.
• Multi-market optimisation: battery charge and discharge plans optimised every 30 minutes.
• Automated bidding: market bids and OCCTO plan files generated and submitted automatically.
• Real-time control: settlement results fed into live battery dispatch.
• Asset management: financial modelling, investor reports and portfolio anomaly detection.

Vietnamese renewable developers preparing for direct power purchase agreements could use multi-market forecasting and optimisation. Owners of solar plus battery projects could automate charge and discharge schedules around tariff windows. Japanese-invested energy companies operating in Vietnam could replicate portfolio reporting across assets.

A lean team can run hundreds to thousands of distributed assets because integrations, bidding and reports are automated. In a published one-year simulation, forecast-based battery control improved battery revenue by 7.40% over fixed-time operation. Investor and forecast-versus-actual reports are generated in minutes, and asset owners keep ownership and revenue under managed aggregation.

Japan is moving renewables from fixed feed-in tariffs to market-based premiums and opening balancing markets to batteries, so owners need forecasting and trading tools. Vietnam's direct power purchase mechanism and planned battery storage build-out point to similar needs for aggregation and battery optimisation software in Southeast Asia.
