Summary · why it matters

Hitachi Energy, in collaboration with the Electricity Generating Authority of Thailand, is preparing to carry out the world's first EconiQ Retrofill project at a voltage level of 550 kilovolts in Thailand, with completion scheduled by December 2026. The project will upgrade a 130-metre gas-insulated transmission line at the Nan high-voltage substation, replacing SF₆ gas with a more environmentally friendly gas mixture. It is expected to reduce SF₆ gas usage by approximately 800 kilograms and avoid greenhouse gas emissions equivalent to around 97 tonnes of carbon dioxide, cutting environmental impact by more than 95%. This project is part of EGAT's approach to enhancing the efficiency of existing infrastructure and supports Thailand's goal of achieving net-zero carbon emissions by 2050.

Valmont Industries Raises 2026 Guidance as Shares Trade Below Fair Value

Valmont Industries has raised its 2026 sales and earnings guidance, a move that comes after an 18.6% six-month share rally tied to utility demand and grid modernization. The stock is up 15.3% year to date and has delivered a 1-year total shareholder return of 27.4%, while its 3-year and 5-year total shareholder returns of just over 2x reflect the payoff from the grid modernization theme. Against a last close of $474.64, the most followed valuation narrative pins fair value at about $624.50, implying the shares are 24% undervalued. Valmont's investments in capacity, automation, and AI are expected to unlock between $350 and $400 million in incremental annual revenue and support higher earnings and margins as the multi-year cycle unfolds. The bullish case leans heavily on infrastructure and agriculture cycles, so weaker project spending or sustained material cost pressure could quickly challenge that 24% discount story.

Eknat Unveils Energy Restructuring Plan, Reserving 10,000 Megawatts of Rooftop Solar for the Public

Energy Minister Eknat Prompan has unveiled a major energy restructuring plan, under which the government will reserve 10,000 megawatts of rooftop solar generating capacity specifically for the public, set at roughly 5 kilowatts per household, to spread the right across households nationwide. Under the new approach, the state will buy back surplus power and apply it as a discount on the same billing cycle's electricity bill. A 5-kilowatt system can generate about 600 to 700 units per month, worth roughly 2,000 baht or more, and the state will provide a subsidy of 50,000 baht, with the income from the generated power used to pay it off. The equipment is expected to be fully paid off in about 7 to 10 years. On cutting permitting steps, coordination will be handled solely through the distribution utilities, with a target of about 1 week for inspection and acceptance in self-consumption installations, and no more than 1 month in cases of selling power back. For the new Power Development Plan, or PDP, three goals are set: cleanest, most stable, and fairest. It targets raising the share of clean energy from the current level of just over 20% to close to 50% within 10 years, and no less than 65% in the long term, while reducing reliance on spot-market LNG in favor of long-term contracts, and opening the door to future technologies including hydrogen, geothermal, solid oxide fuel cells, and small modular nuclear reactors, or SMRs. Meanwhile, the public electricity cost that has been embedded in the power tariff structure for 30 to 40 years amounts to a burden of about 18 billion baht per year. The government has removed this burden from the structure and has already implemented a measure capping the first 200 units of household electricity at 3 baht per unit.

INVX Says Clearer Data Center Rules to Lift Clean Energy and Industrial Estate Stocks, Recommends Selective Buy

The equity and derivatives market strategist at InnovestX Research, InnovestX Securities, said efforts to push Thailand as a regional data center hub are taking clearer shape after the first meeting of the Data Center Business Policy Committee resolved to accelerate integration of data and legal provisions into a single dashboard, in order to set a clear industrial strategic framework within one month. The criteria define data centers using more than 2 MW of electricity as industrial businesses, set resource utilization fees to reflect true direct and indirect costs, and impose strict energy conditions to support Green Data Centers, including a separate electricity tariff category for the group, a mandatory clean energy share of no less than 60% to meet Net Zero goals, and tighter standards for backup power systems. Four subcommittees will be set up covering the economy, infrastructure, land and buildings, and the environment to draw up technical standards, and decisive measures are being prepared to suspend water and electricity allocation for projects not yet under construction if they fail the criteria. InnovestX assesses that these clearer policies will create significant positive ripple effects for two main industries. The first is clean energy, where the 60% minimum clean energy requirement will turn clean power from an option into a necessity, sharply driving real demand. The second is industrial estates, where classifying data centers as industrial businesses will draw foreign direct investment, or FDI, into leading estates equipped with smart grid networks and environmental management, leaving estates reliant on fossil fuels far behind. The investment strategy therefore recommends Selective Buy, focusing on accumulating leaders in these two main industries. For industrial estates, it favors companies with stable smart grid networks sufficient for Tier 3-4 data centers, joint ventures with multinational technology firms, and their own water recycling management systems, namely AMATA and WHA. For clean energy, it favors companies making progress on direct power purchase agreements, or Direct PPAs, with global hyperscalers, with high ESG scores and green certificates, and investing in battery energy storage systems, or BESS, to maintain the stability of electricity supplied to data centers, namely GULF, GPSC and BGRIM, as well as GUNKUL, a contractor for high-voltage transmission line systems.
