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 ba
