Microsoft has strengthened its long-term commitment to decarbonization by signing three new 20-year renewable energy purchase agreements (PPAs) with clean energy developer Shizen Energy in Japan. The partnerships, focused on new solar power projects in the Kyushu and Chugoku regions, mark a significant expansion of Microsoft’s renewable energy footprint in Asia and highlight Japan’s growing appetite for corporate clean power procurement. The agreements bring the total renewable energy capacity contracted between the two companies to 100 MW across four solar projects, building on their initial 25 MW deal signed in 2023 for the Inuyama City project, which was Microsoft’s first-ever renewable PPA in Japan. With one of the new plants already operational and others under construction, all projects have now reached financial close, signaling strong investor confidence in Japan’s evolving clean energy market.

A Major Step in Microsoft’s Global Sustainability Roadmap

The new agreements represent another milestone in Microsoft’s global sustainability journey. In 2021, the company unveiled its “100/100/0” clean energy vision, committing to match 100 percent of its electricity consumption, 100 percent of the time, with zero-carbon energy purchases by 2030. This target builds on its broader pledge to power all global operations including data centers, offices, and campuses with 100 percent renewable energy by 2025. Beyond renewable procurement, Microsoft has set ambitious climate goals: becoming carbon negative by 2030 and removing all historical carbon emissions from the atmosphere by 2050. These long-term contracts with Shizen Energy reinforce Microsoft’s strategy of securing clean, local energy supplies to decarbonize its operations while contributing to national renewable energy growth.

Expanding Japan’s Corporate Renewable Market

The deal also highlights a turning point for Japan’s renewable energy sector, where corporate PPAs are beginning to gain traction. Historically, Japan’s electricity market structure and regulatory barriers limited direct agreements between producers and corporate buyers. However, recent policy reforms and rising demand for ESG-aligned business models have opened the door for new collaborations between technology firms, utilities, and renewable developers. Shizen Energy’s partnership with Microsoft underscores this momentum. The company emphasized that securing both domestic and international financing for the projects demonstrates growing confidence in Japan’s renewable PPA market. As more corporations adopt science-based targets and net-zero commitments, such long-term agreements are expected to play a central role in decarbonizing Japan’s corporate energy mix.

Driving Investment Confidence and Financial Innovation

Each of the four solar projects backed by the Microsoft–Shizen Energy partnership has achieved financial close, indicating robust support from the investment community. Long-term PPAs such as these provide revenue stability for renewable developers and create bankable frameworks for green infrastructure expansion. Rei Ushikubo, Executive Officer of Shizen Energy, highlighted the significance of the deal, stating, “Following the Inuyama Project, we are honored to have signed long-term agreements with Microsoft for several new projects. Securing financing from both domestic and international institutions proves the growing trust in renewable power purchase agreements in Japan. We will continue to expand our PPA business to support our customers’ decarbonization efforts.” By combining stable financing mechanisms with global corporate demand, Japan is now positioning itself to attract greater investment in renewable capacity, particularly in solar and offshore wind sectors that align with its national carbon neutrality goals for 2050.

Technology and Clean Energy Convergence

For Microsoft, the partnerships also align with its broader mission to make technology a catalyst for sustainability. As cloud computing and AI operations demand increasing amounts of electricity, renewable sourcing has become essential to offset emissions from data centers and digital infrastructure. In markets like Japan, where energy imports and grid constraints present unique challenges, long-term solar agreements provide both environmental and operational advantages. They ensure predictable energy pricing, enhance local supply reliability, and contribute directly to grid decarbonization efforts. The move also supports Japan’s ambition to derive 36–38 percent of its electricity from renewables by 2030 under its Strategic Energy Plan.

Looking Ahead: Scaling Corporate Decarbonization in Asia

The Microsoft–Shizen Energy partnership is likely to set a precedent for other multinational companies operating in Japan and across Asia. As corporations seek to localize renewable procurement and meet Scope 2 emission targets, the demand for long-term clean power agreements is expected to surge. With global investors increasingly prioritizing ESG performance, projects like these demonstrate how corporate power buyers can accelerate energy transition in regions where renewable penetration remains below global averages. For Japan, the growing adoption of PPAs could unlock billions in private-sector investment, create green jobs, and reduce dependence on imported fossil fuels.

For Microsoft, the deals reaffirm that climate ambition and business growth can advance hand in hand. By deepening its renewable partnerships and aligning with local developers like Shizen Energy, the company continues to turn its global sustainability commitments into measurable regional impact — setting an example for other tech giants navigating the path toward net zero.
