HALOWS Co., LTD., AkiyamaKousan Co., Ltd.., and ENERES Co., Ltd. have concluded a contract regarding an offsite PPA^[1]. Operations are scheduled to begin in December 2024.

This contract involves supplying renewable energy generated by AkiyamaKousan’s non-FIT solar power plants in Kagawa Prefecture to 11 supermarket stores operated by HALOWS in the Shikoku area through ENERES and its subsidiary power retail company, ENERES Power Marketing Co., Ltd. This is expected to cover 20% of the electricity used by each store with said renewable energy. For electricity shortfalls in the offsite PPA, EPM will supply effectively renewable energy[2], achieving 100% effective renewable energy for all 11 locations. The contract period is 10 years[3].

A distinctive feature of this offsite PPA is that it achieves “local production for local consumption” by utilizing all locally generated renewable energy within the region, taking advantage of HALOWS’ business characteristics.
In typical PPA models, user companies cannot consume all renewable energy during non-operational hours, resulting in surplus. HALOWS operates 24-hour, year-round supermarkets and can fully utilize the local renewable energy generated by AkiyamaKousan in their own stores without waste.

HALOWS, which is based in the Chugoku, Shikoku, and Kansai regions, has been working on climate change measures from an energy perspective for some time. In 2014, they installed a mega solar system on the roof of their logistics center, and since 2016, they have introduced onsite PPAs and other measures[4] at 82 stores and 2 facilities, continuously promoting energy conservation and renewable energy implementation in logistics and stores.

AkiyamaKousan, which operates a real estate business in Kagawa Prefecture, has been advancing renewable energy-related business with the belief in contributing to regional development through corporate activities. Currently, they operate 11 FIT power plants with approximately 14.7 MW capacity in the prefecture, generating renewable energy equivalent to the consumption of 3,200 general households. The power plant used in this contract is a floating solar power facility utilizing a local reservoir and represents AkiyamaKousan’s first non-FIT power generation business.

ENERES leverages its founding business of supply and demand management technology and VPP technology cultivated through demonstration projects and real business to develop various solutions that support both social decarbonization and stable power supply. Offsite PPA, which connects companies with power generators, is one of these solutions. In this contract, ENERES supports renewable energy aggregation[5]for AkiyamaKousan’s first entry into non-FIT power generation business, while supplying renewable and effectively renewable energy to HALOWS,supporting the realization of this offsite PPA

HALOWS, AkiyamaKousan, and ENERES will promote local production and consumption of renewable energy power and its efficient utilization, contributing to the realization of carbon neutrality in Japan.

[1] Offsite PPA (Power Purchase Agreement) is a long-term contract for power users (consumers) to purchase renewable energy power and environmental value from power generators. Offsite refers to an arrangement where providers install renewable energy generation facilities outside the user’s premises, enabling users to utilize renewable energy even when they cannot install generation facilities on their own premises.

[2] Supplies a shortage supplementation menu (effectively 100% renewable energy) utilizing non-fossil certificates with tracking.

[3] Both generation side (renewable energy aggregation contract) and demand side (retail contract for shortages) are 10-year contracts.

[4] As of November 2024.

[5] Tasks including renewable energy generation forecasting, creation of generation plans based on forecasts, formation of power generator balancing groups to eliminate discrepancies with planned values, and correction of discrepancies with planned values using storage batteries.
