I Squared Capital, the Miami-headquartered global infrastructure investment manager, and South Korean construction firm GS E&C have signed a Memorandum of Understanding to establish a joint venture focused on developing renewable energy projects across South Korea, targeting a combined capacity of 1.5 gigawatts by 2035.

The announcement, made marks what the two partners describe as one of the first large-scale renewable energy developer initiatives undertaken by a major Korean conglomerate.

Deal Structure and Project Targets

Under the terms of the MoU, the proposed joint venture will concentrate on solar power and battery energy storage system projects within South Korea. Of the 1.5GW total target, solar power assets are expected to account for approximately 820 megawatts, with battery energy storage systems making up the remainder of the portfolio.

The partnership will operate through a dedicated development company, referred to as a DevCo, through which GS E&C will take the lead on new business opportunity development, permitting and site acquisition, and early-stage project structuring.

GS E&C will also provide project management and technical advisory services, drawing on its domestic and international renewable energy project experience. I Squared and GS E&C will jointly evaluate opportunities and conduct project feasibility assessments throughout the development process.

Roles and Complementary Capabilities

The joint venture is structured to leverage distinct strengths from each partner. I Squared brings what it describes as global infrastructure investment expertise and experience across the energy transition sector.

The firm currently manages over USD 60 billion in assets across more than 100 portfolio companies operating in more than 70 countries, with offices spanning Abu Dhabi, London, Munich, New Delhi, São Paulo, Singapore, Sydney, and Taipei in addition to its Miami headquarters.

GS E&C, which has been operating in Korea and overseas since its establishment in 1969, contributes local market knowledge, engineering capabilities, and a project execution track record accumulated across housing, building, infrastructure, and plant sectors.

In recent years, the company has been expanding into what it characterizes as future growth areas, including data centers, modular construction, renewable energy, and smart cities.

South Korea's Renewable Energy Ambitions

The partnership comes against the backdrop of South Korea accelerating its push to expand renewable energy generation. The South Korean government has set a target for renewables to account for at least 20 percent of electricity generation by 2030, a policy trajectory that both partners say underpins the commercial rationale for the venture.

Gautam Bhandari, Managing Partner and Chief Investment Officer of I Squared Capital, characterized South Korea as a strategically important market for the firm.

"We see significant opportunities to support the country's energy transition through investment in essential energy infrastructure," Bhandari said. "By partnering with GS E&C, we are bringing together complementary capabilities to develop a meaningful pipeline of renewable energy projects that can contribute to South Korea's growing demand for reliable, sustainable power."

Ryu Young-ha, Head of the Renewable and Power Business Department at GS E&C, framed the joint venture within the company's response to global carbon neutrality trends. "We are expanding our business portfolio into various renewable energy sectors, including solar power," Ryu said.

"Going forward, we plan to continue identifying new business opportunities by securing development rights and discovering demand sources both domestically and internationally."

Strategic Significance for Both Partners

For I Squared, the deal is described as further strengthening the firm's existing presence in South Korea. The company positions itself as a specialist global infrastructure investor with deep experience across Asia, and the joint venture with GS E&C extends its footprint in the energy transition space in the region.

For GS E&C, the partnership is presented as a reflection of its mid- to long-term strategy to expand its presence in renewable energy and other energy transition-related sectors. The company has built its domestic profile in part through its premium residential brand Xi, while simultaneously pursuing diversification into growth sectors beyond its core construction operations.

Market Context

The 1.5GW development target positions the joint venture as a substantial contributor to South Korea's renewable energy buildout at a time when the country is seeking to reduce dependence on conventional power sources.

Battery energy storage systems feature prominently in the partnership's scope, reflecting the broader industry recognition that storage capacity is an essential complement to intermittent solar generation.

The involvement of a major Korean conglomerate through GS E&C, combined with I Squared's institutional capital and global infrastructure experience, signals growing interest from international infrastructure investors in South Korea's energy sector as the government's 2030 renewables target draws closer. The formal establishment of the joint venture remains subject to the completion of definitive agreements following the MoU signing.
