Gulf Energy: Power Portfolio and the Data-Centre Build

Questions this report answers

How large is Gulf's power business and what drove the FY2024 growth? Gulf reported FY2024 total revenue of THB 124.6B🔒 (+7%🔒 YoY) and core profit of THB 18.4B🔒 (+18%🔒 YoY) per the company's investor newsroom. The core profit growth was driven by the energy business and share-of-profit from Intouch Holdings (which Gulf had already invested in before the full absorption). The Q3 2025 record core profit of THB 7.28B🔒 (+3%🔒 QoQ) confirms the AIS pillar is compounding post-merger.^{[1, 2]}

What is the Intouch-AIS merger, and how does it change the investment thesis? In April 2025 Gulf completed a share-swap absorption of Intouch Holdings, consolidating AIS — Thailand's largest mobile operator — directly onto Gulf's equity. Singtel, which had held ~21%🔒 of Intouch, was diluted to approximately 9%🔒 of the merged entity. Ratanavadi family control rose to ~59.7%🔒. From Q3 2025 the AIS share-of-profit is a discrete earnings line that structurally re-rates Gulf from a pure power IPP toward an energy-and-telecom infrastructure conglomerate.^{[6, 1]}

How mature is the GSA Data Center JV and what is the capacity path? Gulf, Singtel, and AIS broke ground on the GSA Data Center in March 2024. Phase 1 is 25 MW, already fully booked per Kaohoon International. The ambition is 300-500 MW over three to five years. Phase 2 is planned in the Eastern Economic Corridor. Revenues from Phase 1 are estimated at THB 2-3B🔒 per year. No hyperscaler-level customer is publicly named.^{[3, 4]}

What is Gulf's renewable energy pipeline and the PDP 2024 positioning? ADB committed USD 820M🔒 to co-finance Gulf's 649 MW solar projects with 396 MWh battery storage — one of the largest renewable-financing transactions in Southeast Asia. Gulf's domestic solar portfolio stood at 597 MW with BESS commissioning in late 2025. Under PDP 2024-2040 renewable share is targeted to reach 51%🔒 of Thailand's contracted capacity by 2037, a structural multi-year tailwind for Gulf's solar and wind pipeline.^{[8, 10, 1]}

Executive summary

Gulf Energy Development has transformed from a gas-fired IPP into a diversified energy-and-digital infrastructure conglomerate over the 2023-2025 period. The gas-fired core remains the cash engine: Gulf's combined-cycle and SPP plants run at contracted capacity factors under 20-25-year EGAT PPAs, generating predictable EBITDA that funds the diversification build-out. FY2024 revenue of THB 124.6B🔒 and core profit of THB 18.4B🔒 are the highest in the Thai listed-IPP peer set by a material margin.^[2]

The AIS merger is the single most significant structural change in Thai IPP history. No peer has attempted a telecom-power conglomerate at this scale. AIS share-of-profit contributed a material portion of the Q3 2025 record THB 7.28B🔒 core profit, and the segment will compound as AIS's 5G and fibre-broadband rollout monetises. Singtel's dilution to ~9%🔒 reduces the strategic constraint on Gulf's data-centre and digital-infrastructure ambition, since Singtel's GSA Data Center stake (35%🔒) is now aligned with, not competing against, Gulf's interests.^{[1, 6]}

The data-centre and digital pillar is nascent but structurally advantaged. The GSA JV's Phase 1 25 MW being fully booked before commercial opening signals real demand from enterprise and, potentially, hyperscaler colocation customers. Gulf's power-supply depth (own-generation on site or adjacent) is a differentiator for data-centre power security. The Hin Krut LNG terminal (commercial 2029) and the Vietnam wind and solar portfolio (Mekong Wind 128 MW, GTN1/GTN2 119 MW) round out an optionality set no Thai peer can replicate.^{[4, 9, 12]}
