What Pacifico Energy does

Pacifico Energy K.K. (パシフィコ・エナジー株式会社) is a privately held Japanese renewable energy developer founded in September 2012 and headquartered at Roppongi Grand Tower in Minato-ku, Tokyo. The company develops, constructs, and operates utility-scale solar photovoltaic power plants, grid-scale battery energy storage systems (BESS), electricity power trading operations, and offshore wind projects. As of 2025, Pacifico has developed and commissioned 1,293 MW (DC basis) of solar capacity across 11 prefectures, representing one of Japan's largest utility-scale solar portfolios, with over 1 GW of capacity certified by the Ministry of Economy, Trade and Industry (METI). Cumulative generation since founding totals 8.3 billion kWh with 3.97 million tonnes of CO2 emissions reduction. The company also holds a 500 MW offshore wind site survey license in Vietnam and is developing offshore wind sites in Japan through the SSE Pacifico K.K. joint venture with UK-based SSE Renewables (established October 2021). Pacifico has offices in Japan, Vietnam, South Korea, and the United States, with US operations focused on private grid infrastructure for data center customers (including the 7.65 GW GW Ranch project in Texas).

The company's core technology stack spans utility-scale solar PV, grid-scale lithium-ion battery storage (with Tesla Megapack referenced for US projects), and a proprietary in-house market forecast AI system that processes weather, solar radiation, wind speed, and economic time-series data to forecast electricity demand and supply. The AI system supports power trading strategy and BESS charge/discharge optimization in Japan's wholesale (JEPX), balancing, and capacity markets. Pacifico has built a vertically integrated BESS framework covering development, design, procurement, construction management, market trading strategy, and asset management, with merchant BESS assets operational in Hokkaido (Shiroishi), Kyushu (Itoshima), and Tokyo (Koganai) markets. The company's "full merchant" BESS model operates without government subsidies, in contrast to its legacy solar assets which generate revenue primarily under feed-in tariff (FIT) contracts with regional electric utilities.

Pacifico's business model combines long-term FIT-backed power purchase agreements with Japan's regional electric utilities for solar generation (Chugoku Electric, Tohoku Electric, Kyushu Electric, Chubu Electric, Kansai Electric, Kansai Transmission and Distribution, TEPCO Energy Partner are named offtakers), merchant-based BESS revenue from electricity markets, asset management services, and emerging data center private grid revenue. The company has raised over $3.5 billion USD in equity and debt finance since founding, including two private placement funds (15.5 billion yen in February 2018 and 29 billion yen in 2019) and project-level syndicated debt from MUFG Bank, Sumitomo Mitsui Trust Bank, Shinsei Bank, Bank of Fukuoka, Mitsubishi HC Capital, and BOT Lease. Strategic EPC partners include JGC Japan, Toyo Engineering, Chiyoda Corporation, Sharp Energy Solutions, juwi Shizen Energy, and RAIZNEXT. President and CEO Hiroki Matsuo has led the company since June 2019, with the management team drawing from Mitsubishi Corporation, Fortress Investment Group, Merrill Lynch, Accenture, Panasonic, Sumitomo Electric, and JGC Corporation.

Revenue model

1. Solar Power Generation and Sales: Pacifico Energy develops, constructs, and operates utility-scale solar photovoltaic power plants. Revenue is generated through feed-in tariff contracts with regional utility companies and direct power sales in the liberalized electricity market.
2. Battery Energy Storage System Operations: Grid-scale battery storage systems generating revenue through participation in daily electricity markets (capacity, balancing, and wholesale) rather than long-term bilateral contracts - a 'full merchant' model.
3. Power Trading: Trading activities in the market for buying and selling electricity, including forecasting demand and supply, charging/discharging storage batteries during optimal periods, and providing regulating power and reserve power.
4. Offshore Wind Development: Joint venture SSE Pacifico K.K. developing offshore wind projects in Japan, with revenue expected from power generation once projects reach operational stage.
5. Asset Management Services: Asset management services for solar power plants including engineering, construction, operation, maintenance and monitoring.

Direct peers

• Eurus Energy Holdings: One of Japan's largest independent renewable energy developers with utility-scale wind and solar across Japan. Pacifico Energy's CEO Hiroki Matsuo previously led solar and wind development at Eurus, and both compete for Japanese land sites, FIT/corporate PPAs, and project-finance relationships with MUFG and other Japanese lenders.
• Shizen Energy Inc. Japanese independent power producer developing solar, wind, and biomass projects with a vertically integrated platform that also covers retail electricity supply. Directly competes with Pacifico for Japanese land, offtake contracts, and increasingly for the merchant BESS / power-trading opportunity through JEPX.
• SB Energy (SoftBank Group): SoftBank's renewable energy arm operating one of Japan's largest solar and wind portfolios including mega-solar projects. Overlaps with Pacifico on utility-scale solar development, FIT contracts, and competition for engineering resources and EPC partners such as JGC and Chiyoda.
• Renova Energy (Renova, Inc.): Tokyo-listed renewable IPP with a diversified portfolio of solar, wind, biomass, and geothermal projects across Japan. Comparable in development scope, project-finance structure, and ambition to expand beyond FIT solar into merchant and corporate PPA markets that Pacifico is targeting with its BESS and trading business.
• SSE Renewables: UK-listed SSE's renewables arm and Pacifico's joint venture partner in SSE Pacifico K.K. for Japanese offshore wind development. Most directly comparable offshore wind developer with comparable scale, project-development discipline, and grid-integration expertise relevant to Pacifico's offshore wind ambitions.

Broad incumbents

• JERA Co., Inc. Japan's largest power generator formed by TEPCO and Chubu Electric, with a growing renewables portfolio and significant trading capability. A scale-incumbent buyer of renewable power and a potential strategic counterparty rather than a direct head-to-head rival in development, but increasingly competes in the BESS and capacity markets Pacifico is targeting.
• RWE Renewables Japan: Subsidiary of German utility RWE with offshore wind and onshore renewables development in Japan. Pursues the same Japanese offshore wind opportunities enabled by the SSE Pacifico JV and competes for corporate PPAs with major Japanese corporates and for grid connections.
• Enel Green Power Japan: Japanese arm of Enel's global renewables business, operating solar and wind projects and increasingly pursuing BESS in Japan. Comparable as a foreign-incumbent developer with the capital, technology, and offtake relationships that Pacifico competes against in Japanese utility-scale tenders.
• Iberdrola Renewables Japan: Spanish utility Iberdrola's Japanese renewables arm, active in offshore wind development in Japanese waters and selected solar projects. Competes for the same offshore wind sites and corporate renewable PPAs that the SSE Pacifico JV is targeting.
• Ørsted Japan: Danish offshore wind leader with a growing Japanese portfolio and one of the few foreign developers active in Japanese offshore wind tenders. Highly comparable as a global offshore wind specialist with the kind of expertise that the SSE Pacifico JV is bringing to bear in Japan.
