Electricity Generating Public Company Limited, known as EGCO Group, has announced the successful completion of its acquisition of a 49% membership interest in the Pinnacle IV Portfolio, a pair of operating renewable energy projects in the United States with a combined generating capacity of 339 MW.

Acquisition Closes With Immediate Effect

The transaction was officially completed on 25 September 2026 through EGCO Pinnacle IV, LLC, a wholly owned subsidiary of EGCO Group. The deal was carried out alongside the company's global project development partner, Apex Clean Energy Holdings, LLC, which retains the remaining 51% membership interest in the portfolio.

Because both projects in the portfolio are already in commercial operation, EGCO Group is able to immediately recognize cash flows and its share of profit from the transaction closing date.

The company describes this as a reflection of its disciplined and proactive capital allocation and notes that the assets carry no development risk since they have already reached commercialization.

The Assets: Timbermill Wind and Coldwater Solar

The Pinnacle IV Portfolio comprises two facilities. The first is the 189 MW Timbermill Wind facility located in the state of North Carolina. The second is the 150 MW Coldwater Solar facility in the state of Michigan. Together, the two operating projects deliver an aggregate generating capacity of 339 MW.

The portfolio carries three strategic highlights, according to the company. The first is the immediate revenue recognition with zero development risk, as both projects are commercially operating and therefore generate returns and cash inflows to EGCO Group starting from the transaction closing date.

The second is the strategic footprint in what the company describes as the largest U.S. renewable energy markets, PJM and MISO, where the assets in North Carolina and Michigan operate in regions characterized by strong electricity demand and reliable grid infrastructure designed to support clean energy growth.

The third is the stability of cash flows, which are backed by long-term power and environmental attribute offtake arrangements and Renewable Energy Certificates contracts with investment-grade offtakers, providing stable and predictable revenue streams over the long run.

Impact on EGCO Group's Renewable Capacity

The transaction lifts EGCO Group's total renewable energy capacity to 1,785 MW, which now accounts for 26% of the company's overall equity capacity. As of 28 September 2026, EGCO Group reports a total equity contract capacity of 6,928 MWe, comprising both operating assets and projects under construction.

The renewable portfolio spans multiple technologies, including biomass, hydropower, solar, onshore and offshore wind, fuel cells, and battery energy storage systems.

The company frames the acquisition as part of its commitment to driving the organization toward a low-carbon society and its continued expansion of green energy assets both domestically and internationally, with a focus on high-quality assets backed by long-term offtake arrangements in the PJM and MISO markets.

Leadership Comments on Strategic Direction

Mr. Tawatchai Sumranwanich, President of EGCO Group, stated that the company maintains a clear strategic direction and policy to accelerate the expansion of its green energy portfolio across both domestic and international projects.

He described the acquisition of the Pinnacle IV Portfolio as another major milestone under the company's "POWER4" strategy, which emphasizes "Profitability and Performance Energizing." According to the president, the company selectively invests in high-quality, commercially operating renewable assets to foster balanced growth, elevate its clean energy proportion worldwide, and enhance long-term earnings stability.

Mr. Tawatchai added that EGCO Group will continuously advance its green energy portfolio by preparing for upcoming domestic renewable power tenders under Power Development Plan PDP 2026 and Direct Power Purchase Agreement (PPA) while aggressively expanding clean energy assets abroad, particularly in the United States, which the company identifies as its secondary strategic base.

Synergy With Existing US Holdings

The Pinnacle IV Portfolio is expected to create strategic synergy with EGCO Group's existing power assets in the United States, which include Apex Clean Energy, Pinnacle II, Linden Cogen, and the Compass Portfolio.

The company says this combination creates a highly flexible and resilient portfolio structure that positions it to respond to the megatrend of surging green electricity demand driven by the rapid growth of data centers, AI technology, and future industries.

Mr. Tawatchai said the synergy further underscores the company's strict financial discipline and its commitment to delivering sustainable, "Gold Standard" returns to shareholders.

The company is focusing on increasing clean energy capacity globally and seizing what it calls "Gold Standard" growth opportunities driven by data center and AI expansion.

Powering Ahead: Stay Ahead of the United States' Energy Development Curve

What separates the companies that win power sector contracts from those that chase them? In most cases, it comes down to timing, knowing about a grid expansion, gas plant upgrade, or renewable buildout months before the competition does. In the United States, where transmission modernization and clean energy targets are reshaping the project pipeline, that early visibility is no longer optional.

Tracking capital investments, permitting milestones, and contractor activity across dozens of states manually is a losing proposition. The Global Project Tracking (GPT) platform by Blackridge Research consolidates everything you need into a single, always-current database, so your business development and strategy teams can act on verified intelligence instead of scattered rumors.
