Tensor Energy Launches Call for Partner EPC Companies to Promote FIP Transition of FIT Solar Power Plants

Tensor Energy Co., Ltd. (Headquarters: 1-11-1 Tenjin, Chuo-ku, Fukuoka City; Representatives: Nana Hori, Carlos Vincent Filter; hereinafter "Tensor Energy") announces the launch of a recruitment program for partner EPC companies to promote the transition of FIT solar power plants to the FIP scheme (hereinafter "FIP transition").

Tensor Energy Launches Call for Partner EPC Companies to Promote FIP Transition of FIT Solar Power Plants

Starting April 2027, the "priority supply rule" regarding output suppression will change, making FIT power sources subject to output control before FIP power sources. Ahead of this change, and amid growing concerns over further deterioration in profitability of FIT solar power plants—particularly in the Kyushu region—Tensor Energy is launching a partnership program to collaborate with EPC companies nationwide. This initiative aims to jointly deliver value to power plant owners through FIP transition and create new revenue streams for EPC businesses.

Background: Changes to Priority Supply Rules and the Necessity of FIP Transition

According to the "Long-term Outlook on Renewable Energy Output Control" published by the Agency for Natural Resources and Energy in June 2025, after the revision of the priority supply rules, FIT power sources will be prioritized for output suppression over FIP power sources. As output suppression becomes increasingly frequent nationwide, FIT power plant owners face significant long-term risks of reduced electricity sales revenue.

In contrast, transitioning to FIP can substantially reduce the risk of being subjected to output control under the revised rules. Additionally, by co-locating battery storage systems, power plants can participate in the supply-demand adjustment market and generate additional revenue. Thus, FIP transition represents a strong strategic option for plant owners and opens up multifaceted business opportunities for EPC companies—including construction contracts, PCS replacements, and battery installation proposals.

Overview of the FIP Partner Program

Tensor Energy is seeking EPC companies to partner with in advancing FIP transition. Partner companies will receive the following support:

Partner Benefits

Free provision of FIP transition and battery co-location simulation tools

Partial return of aggregation fees as ongoing stock fees

Paid support for FIP transition applications (end-to-end assistance from document preparation to approval)

Sales and technical support from Tensor Energy’s business development team

Benefits for EPC Companies

Turn the priority supply rule change into a new sales opportunity

Propose FIP transition as a reliable solution to mitigate output control risks for plant owners.

Secure construction contracts for PCS replacement and battery installation

Obtain stable construction revenue through contracts related to PCS replacement and battery installation accompanying FIP transition.

Generate continuous revenue via stock fees

A portion of the aggregation fees will be continuously returned to partner companies. Opportunities for O&M service contracts may also arise.

Pathway to participation in the supply-demand adjustment market

By installing battery storage, plants can increase profitability through participation in the supply-demand adjustment market via Tensor Cloud.

Tensor Energy’s Strengths

Since its founding in 2021, Tensor Energy has developed and provided "Tensor Cloud," an AI-powered optimization platform for renewable energy power generation businesses. The platform is currently deployed in over 194 MW of power plants (1,051 sites). Tensor Energy also operates Japan’s first※1 large-scale battery storage system co-located with an FIP project, developed in collaboration with Tokyo Century Corporation (operation started June 2024).

High-accuracy AI-based forecasting of power generation and market prices, with real-time optimal control every 30 minutes

End-to-end support from FIP transition simulation and application to aggregation services

Extensive experience supporting FIP transitions and evaluating battery co-location projects, particularly in the Kyushu region

Total funding raised: 1.65 billion JPY from investors including Globis Capital Partners and Mizuho Capital

※1 "Japan’s first" based on internal research. Deployment and funding figures are as of June 2026.

Eligibility and Requirements

EPC companies involved in construction and O&M of low-voltage FIT solar power plants

Companies capable of, or aiming to, assemble FIP transition projects of 1 MW or larger

Companies with access to plant owners across Japan, especially in the Kyushu region

※ For power plants subject to split eligibility concerns, transition to the FIP scheme may not be possible under current regulations. Please contact our business development team for details.
