New Zero-Cost Solar Power Feed-in Tariff Guarantee Service to Minimize Sales Loss

Introduction

Omron Social Solutions Corporation (OSS) is set to launch a groundbreaking service in May 2026 aimed at assisting solar power operators in the Kyushu region of Japan. This service, known as the "Low-Capacity FIT Sales Guarantee Service," promises to minimize sales losses caused by output control, all without requiring any initial or monthly costs from the operators. Leveraging advanced battery storage systems, OSS aims to enhance profitability for those utilizing the KPV/KPW solar inverters in their low-capacity solar power plants.

Rising Challenges in Kyushu

Recent times have seen a significant increase in output control in Kyushu, particularly impacting power generation companies operating under the Feed-in Tariff (FIT) system. This has led to growing sales losses due to the mandatory restriction of output during times of excessive power generation. In response, the Japanese government has decided to revise the "Priority Supply Rule," which will come into effect in 2026. The updated rule prioritizes output control for FIT sources over Feed-in Premium (FIP) sources, changing the dynamics for low-capacity solar operators transitioning to the FIP framework.

Addressing Transition Barriers

The shift from FIT to FIP comes with significant challenges, primarily due to the upfront investments in battery systems and the risks associated with variable market prices. OSS, recognized for its proficiency in battery control technology, aims to eliminate the risks related to FIT sales losses through its newly launched service. Drawing on the expertise acquired from its successful high-capacity FIP transition service initiated in November 2024, OSS will support low-capacity solar operators (those generating less than 50kWh) in their transition to the FIP system.

Service Details

1. Zero Initial Investment and Operational Costs
All low-capacity power producers utilizing OSS’s KPV and KPW solar inverters can integrate battery storage solutions into their operations without any capital investment. This opportunity allows them to transition to the FIP framework seamlessly.

2. Increasing Sales Revenue through Output Control Reduction
By applying priority supply rules starting from 2026, the opportunity for output control disruptions will significantly decrease after transitioning to FIP. OSS guarantees operators a fixed amount based on the FIT price multiplied by their electricity sales volume, thus mitigating lost opportunities related to output control. As a result, operators can maintain more stable revenues similar to their original FIT expectations.

3. One-Stop Aggregator Service from OSS
OSS will provide a comprehensive, one-stop solution handling all the complex procedures related to FIP transitions, including battery system control, electricity trading on the JEPX market, and maintenance of the battery systems. The risks associated with fluctuating sales prices will be managed by OSS, enabling operators to focus on their electricity generation business.

Exhibition at PV-EXPO

Interested parties can learn more about this innovative service at the upcoming PV-EXPO being held at Tokyo Big Sight from March 17 to March 19, 2026, at booth No. E1-21 in Hall 4.

Conclusion

Through the Low-Capacity FIT Sales Guarantee Service, OSS aims to help solar power operators overcome the challenges posed by output control and contribute to a sustainable carbon-neutral society by facilitating more effective utilization of renewable energy.
