Prologis (Japan Headquarters: Marunouchi, Chiyoda-ku, Tokyo; Representative Director and CEO: Miki Yamada), a leading global company in logistics real estate ownership, operation, and development, announced the start of operation of grid-scale storage batteries* installed on the premises of "Prologis Park Chiba 1," a leased logistics facility it operates in Chiba City, and its entry into various electricity markets (capacity market, wholesale electricity market, supply-demand adjustment market). The start of operation and market entry began on April 1st. This is the first initiative by a domestic operator to install grid-scale storage batteries on the premises of a logistics facility.
*Grid-scale storage battery: A large-scale storage battery directly connected to the power grid, such as power plants and transmission lines. It uses the electricity market as a revenue source and is used for stabilizing the entire grid and adjusting supply and demand.
■ Business Overview
The total output of the grid-scale storage batteries is 2MW, with a storage capacity of 6MWh. As part of its energy business, Prologis purchases electricity from the electricity market for charging and supplies electricity according to market conditions. The installation site utilized unused space equivalent to 23 parking spots within the "Prologis Park Chiba 1" premises.
■ Role of the Supply-Demand Adjustment Market and Social Background Leading to Business Entry
The supply-demand adjustment market, which is particularly targeted among electricity markets, was established in 2021 as a trading market for real-time adjustment of electricity supply and demand, and fully opened in April 2024. It aims to avoid imbalances in supply and demand that can cause large-scale blackouts, thereby stabilizing the overall power system, including ensuring stable electricity supply and reducing the risk of price surges.

In recent years, fluctuations in power generation have increased due to the widespread adoption of renewable energy (hereinafter "RE"), heightening the need for supply-demand adjustment. However, in Japan, the utilization of large storage batteries and entry into the supply-demand adjustment market are still in their early stages, with few examples from non-energy businesses. Factors hindering entry include high initial investment costs, complex procedures until operation begins, and time constraints from securing business land to starting operation. Furthermore, the immaturity of the supply-demand adjustment market raises concerns about the difficulty of long-term market trend prediction and price fluctuation risks, leading to future uncertainty.
Prologis decided to enter this business in anticipation of the social significance of electricity supply-demand adjustment, the high barriers to entry, and future demand expansion. Leveraging its accumulated knowledge in the energy business and utilizing its idle land, the company capitalizes on its advantage of being able to commercialize quickly with reduced risk, contributing to the promotion of RE expansion and the stabilization of the power system.
■ Prologis's Energy Business
Prologis generates approximately 89MW (as of April 2026) domestically from solar power panels installed on the rooftops of logistics facilities, which will reach 100MW including planned installations at logistics facilities under development.
Regarding the utilization of surplus electricity that cannot be consumed within logistics facilities, Prologis is engaged in initiatives such as self-consignment*1 to other facilities, electricity sales to other companies (PPA: Power Purchase Agreement)*2, and power supply to data centers*3. Furthermore, by utilizing non-fossil certificates*4, it supports the greening of electricity for companies, including tenant customers, thereby providing solutions to corporate sustainability challenges. Examples of past projects are as follows:
【Self-consignment*1】
