Notice Regarding Acquisition of FIP Certification for Uki Solar Power Plant

Remixpoint Inc. (Securities Code: 3825, Headquarters: Minato-ku, Tokyo, President & CEO: Yuhiko Takahashi, hereinafter "the Company") is pleased to announce that it has received transition certification from the Ministry of Economy, Trade and Industry from the FIT system*1 to the FIP system*2 for its "Uki Solar Power Plant" (Uki City, Kumamoto Prefecture), which it owns, as the first project in its FIP conversion business.

*1 Abbreviation for "Feed-in Tariff." A system where the government promises to purchase electricity generated from renewable energy at a fixed price for a certain period.

*2 Abbreviation for "Feed-in Premium." A system where renewable energy power producers receive a certain amount of subsidy (premium) added to the electricity sales price when selling electricity to the wholesale electricity market such as JEPX.

Background and Objectives of the Initiative

Since the introduction of the FIT system, the adoption of renewable energy has progressed rapidly. On the other hand, in recent years, there have been increasing instances where electricity supply exceeds demand. Challenges such as declining wholesale electricity market prices on the Japan Electric Power Exchange (JEPX) during these times and increased output controls on renewable energy generation facilities due to oversupply have become apparent.

According to public materials from the Ministry of Economy, Trade and Industry*3, the areas implementing output control are expanding nationwide with the increased adoption of renewable energy, and the amount of output control is also reported to be on an increasing trend. In particular, some regions, including mainland Kyushu, continue to implement output control at high levels, and a decrease in electricity sales revenue due to output control is a major factor influencing the profitability of power generation businesses.

Against this backdrop, the Company has been promoting FIP conversion projects within the Kyushu Electric Power service area, and has now obtained FIP certification from the Ministry of Economy, Trade and Industry in June 2026 for its wholly owned "Uki Solar Power Plant," its first project.

At this power plant, in conjunction with the transition to the FIP system, a market operation model combining a large-scale storage system with proprietary AI will be constructed. By controlling charging and discharging in response to market prices and electricity supply-demand, we will balance the effective utilization of renewable energy with the stabilization of the power grid, while also participating in multiple markets such as JEPX and the balancing market to maximize electricity sales revenue.

Through the operation of this power plant, the Company will accumulate and demonstrate advanced operational know-how and knowledge in the aggregation business*4, and utilize these results in its grid-connected battery storage business deployed nationwide, thereby creating business synergies and improving corporate value in the mid-to-long term.

*3 From "Regarding Short-Term Outlook of Renewable Energy Output Control, etc." (Materials from the 6th Next-Generation Power Grid Working Group) by the Agency for Natural Resources and Energy, Ministry of Economy, Trade and Industry.

*4 A business that integrates and controls distributed power sources such as solar power generation and storage batteries using IoT, etc., and operates them as a unified entity to adjust supply-demand balance and provide supply capacity and regulation capacity to the market to generate revenue.

Overview of Revenue Model

At this power plant, it is expected that electricity sales revenue, including the balancing market, will increase by approximately 35 million yen annually compared to the conventional FIT system, due to efficient market operation resulting from the transition to the FIP system and the co-location of a storage system.

Furthermore, considering the priority order in future output controls, it is anticipated that charging will occur during daytime hours when market prices are low (including the relevant hours) and discharging (selling electricity) will occur during hours when market prices are high. This will minimize the opportunity loss due to output control and further improve business profitability.

Future Development and Outlook

The Company views this initiative as a model case for FIP conversion of high-voltage solar power plants. By leveraging the market operation, EMS control, and aggregation knowledge and know-how accumulated through power plant operations, we plan to offer FIP conversion support services to renewable energy power plants owned by other companies in the future.

Specifically, by providing integrated services including FIP system transition support, EMS introduction, storage battery integration, and aggregation, we aim to support power generation businesses in improving their revenue and to create diverse revenue opportunities through equipment sales, system construction, and aggregation.

The impact of this matter on the Company's consolidated performance for the current fiscal year is expected to be minor. We will promptly disclose any matters that require public announcement in the future.
