Background:
PATRIZIA, a global investment manager in real assets, and Mitsui & Co., Ltd, one of the world’s leading trading and investment companies, have announced the addition of a strategic Japanese co-investor to YES Group. YES, Group is a vertically integrated renewable energy company with a diverse portfolio of small- to mid-scale solar generation and battery storage assets across Australia.
The co-investment strengthens PATRIZIA’s Japanese investor base and underscores the growing collaboration between European real asset managers and leading Asian investors in supporting the energy transition across the Asia-Pacific region.
Structured as a co-investment alongside the APAC Sustainable Infrastructure Fund (A-SIF), the deal allows YES Group founder Mark Yates to retain his existing interest while providing capital to support the company’s next phase of growth. Patrick Lee, Operating Partner for APAC Infrastructure at PATRIZIA, said the investment highlights the resilience of small-scale, distribution-connected renewables in driving Australia’s energy transition and aims to deliver long-term value for investors.
YES Group currently runs five projects totaling about 34 MWAC / 26 MWh, including standalone solar, battery storage, and hybrid systems in South Australia, the Australian Capital Territory, and New South Wales. Four of these projects are already operational, and the remaining one is expected to start by mid-2026. The company focuses on small local projects, which are safer, more reliable, and easier to manage.
The new investment will fund 4-5 more projects, nearly doubling the company’s generation and storage capacity over the next two to four years to more than 145 MWAC / 330 MWh. Takashi Nakai, General Manager of the Financial Business Division at Mitsui & Co., said the partnership will help speed up renewable energy development and support long-term sustainable growth.
Outside Australia, A-SIF has also invested across the Asia-Pacific region in 2025. These include the Philippines’ rooftop solar developer Buskowitz Energy Inc., a new urban mobility platform, and Kaer Pte. Ltd to grow Cooling-as-a-Service solutions, reflecting the fund’s focus on mid-sized infrastructure projects that promote sustainable development.
