AI Power Demand Surge Makes Five High-Yield Utility Stocks Attractive for Decades

Yuanta Securities (Thailand) has raised its fair value for Ratch Group, or RATCH, to 46.25 baht per share from 32 baht, and upgraded its recommendation from Trading to Buy, implying roughly 25.9% upside from the share price of 36.75 baht on October 1, 2026. In an analysis dated October 2, 2026, the brokerage said it holds a positive view on several new investment opportunities whose prospects became clearer in late 2026, particularly the renewal of the power purchase agreement, or PPA, for the Ratchaburi power plant and the opportunity to sell electricity to data center operators. Currently, units 1-2 of the RG power plant, with combined capacity of about 1,470 megawatts, saw their contracts expire in October 2025, while three remaining units with total generating capacity of about 2,175 megawatts are due to see their contracts expire in November 2027. If the PPAs are not renewed, the company has the option of selling the output to data center operators, and is in talks with about five to six customers, each of which needs no less than 300 megawatts, while the existing site and infrastructure can support demand of up to about 1,400 megawatts. In addition, the draft PDP 2026 plan, which covers 2027-2037 and targets an increase in total power generation capacity of about 50 gigawatts, is another positive factor. It comprises about 24.3 gigawatts of solar power, nearly 14.5 gigawatts of wind power, about 2.7 gigawatts of natural gas-fired plants, about 9.1 gigawatts of hydropower and the first small modular nuclear reactor, or SMR, with capacity of about 300 megawatts. For the third-quarter 2026 outlook, the research team expects RATCH to post normal profit of about 1.4 billion to 1.6 billion baht, up from the previous quarter, after the RG and HKP power plants returned to more efficient operation and with no major maintenance shutdowns. SG&A expenses are also likely to fall on a seasonal basis, but profit is expected to decline from the same period a year earlier, partly because of the impact of the expiry of the PPAs for units 1-2 of the RG power plant from October 2025.

Finansia Securities said GULF is well positioned to link energy infrastructure and ICT businesses with AI, with a strong financial position and capacity to take on an additional 200-300 billion baht in debt. It estimates that added capacity under PDP 2026 could create roughly 10 baht per share of upside for GULF, assuming EGAT opens bidding for about 10GW of new renewable energy projects next year and GULF secures a 40% share, or roughly 4GW of solar projects, under power purchase agreements at a feed-in tariff of 2.16 baht per kWh. Investment is expected to require about 25-30 million baht per MW, with an IRR of approximately 12%. On the AI megatrend, electricity demand is expected to grow faster than GDP, especially demand for clean power from data centers, which are more power-intensive than general industry. Key catalysts include the new PDP, Direct PPAs for 2GW of data centers, and opportunities to invest in renewable energy projects in Europe over the next year. The research team maintained its Buy recommendation and raised its target price to 89.50 baht per share to reflect the opportunity to add capacity from bidding under the new PDP, as well as the acquisition of a 50% stake in solar and wind projects from GUNKUL, representing total capacity of 339.5MW on a proportional ownership basis. The acquired projects are estimated to have a combined NPV of about 9.7 billion baht based on a DCF valuation with a WACC of 5.5%, adding roughly 0.5 baht per share, with net IBD/E of only 1.06 times.

The U.S. Department of Energy has approved a roughly US$4.00 billion federal loan package for Vistra to upgrade three nuclear plants serving the PJM grid, as power demand climbs from data centers and other intensive users. The federal backing supports nuclear capacity upgrades and underscores Vistra's role as a reliability provider in a tightening U.S. power system. The loan sharpens the company's investment narrative around long-term contracted power, though Vistra has separately challenged PJM's Interim Resource Adequacy Service at FERC, arguing the measure could chill investment and misprice capacity for large loads. Vistra's narrative projects $26.0 billion in revenue and $4.1 billion in earnings by 2029, requiring 10.7% yearly revenue growth and a $2.1 billion earnings increase from $2.0 billion today, while some analysts assume revenues near US$33.4 billion and earnings around US$4.9 billion by 2029.
