TSP Launches "Balancing Group Formation Support Service" for High-Voltage Solar Power Owners

Supporting Profit Improvement for High-Voltage Solar Power Plants

TSP Co., Ltd. (Headquarters: Hiroshima Prefecture, CEO: Tane-ko Tada) has launched the "Balancing Group Formation Support Service" targeting owners of high-voltage solar power plants (power conditioner output between 50kW and less than 1000kW).

This service utilizes AI for profit simulations, considering Feed-in Premium (FIP) transition, battery storage introduction, and participation in the supply-demand adjustment market. It further supports the formation of balancing groups (BG) by aggregating plant owners nationwide.

This aims to create new revenue opportunities for plants between 50kW and less than 1000kW, which have previously found it difficult to participate in the market independently.

Background: Profit Improvement for Existing Solar Power Plants Post-FIT Becomes a Challenge

Since the introduction of the FIT system in 2012, numerous solar power plants have been deployed in Japan.

However, in recent years, challenges have become apparent, including:

- Limits to revenue growth from fixed-price electricity sales

- Loss of sales opportunities due to output controls

- Constraints on power generation efficiency from older generation panels

- Expiration of FIT periods

In response to these challenges, our company has been providing the "Operated Solar Power: Doubling Profits with FIP Transition, Market Entry, and Repowering" service for mega solar owners. (Press release dated March 17, 2026).

Subsequently, we received inquiries from many high-voltage plant owners, whose facilities are smaller than mega solar plants, asking if the service could be applied to them and if it could be expanded to high-voltage solar power.

While mega solar plants can meet market participation requirements independently, high-voltage solar power plants between 50kW and less than 1000kW cannot meet the necessary scale for market participation on their own. To enter the supply-demand adjustment market, the formation of a balancing group (BG) by consolidating multiple power plants is required.

Therefore, we have now launched a new balancing group formation support service for high-voltage solar power plants, establishing a system that provides one-stop support from simulation to market participation.

TSP's Balancing Group Formation Support Service

TSP first analyzes the power generation performance, FIT unit price, and equipment conditions for each high-voltage solar power plant and conducts profit simulations using AI.

Based on the simulation results, if the plant owner wishes to participate in the market, we will proceed with forming a balancing group (BG) by combining it with other plants within the same electricity utility's service area.

TSP aggregates project information from high-voltage solar owners nationwide and supports their entry into the supply-demand adjustment market for plants that are difficult to participate in independently.

* Simulation costs are 50,000 yen (excluding tax) per power plant.

* Participation in a balancing group is not guaranteed.

* Formation requires grouping within the same electricity utility's service area, so formation may not be possible depending on the region or project status.

Future Development & Contact Information

TSP Co., Ltd. will contribute to improving Japan's energy self-sufficiency and stabilizing the power infrastructure by maximizing the value of existing renewable energy assets.

Currently, this service is targeted at high-voltage solar power plants between 50kW and less than 1000kW.

Services for low-voltage solar power plants are currently under preparation and will be announced once details are finalized.

We are also recruiting agents to deploy this service.

The solar power generation business is shifting from "an era of generating and selling" to "an era of enhancing value through operation."

With the philosophy of "Creating power infrastructure that lasts for future generations," we will continue to work on improving the value of existing power plants.
