Singapore Unveils Five-Year Energy Plan: New Gas Plants, Grid Expansion and Storage Push to Meet Rising Demand
The most significant build-up of our energy infrastructure in decades
Mark
Why does this plan matter now?
Mimi
Because demand is projected to climb from 8.6GW in August to between 9.9GW and 13GW by 2031, mostly from chipmaking, data centres and electric transport.
Luke
That range is wide. What does it tell us?
Mimi
That the timing of those projects is uncertain. EMA itself says growth depends on when they come onstream.
Mark
And the Indonesian gas cut?
Mimi
It began over the weekend and amounts to under 2 per cent of daily gas demand. Dr Tan used it to show the system can absorb shocks.
Luke
That reassurance is the minister's assessment. The source gives no independent evaluation of how the cut will play out.
Mark
What stands out in the grid spending?
Mimi
Up to S$5.3 billion for 2025 to 2029, eleven times the previous five years, plus seven new substations by 2031.
Luke
Note the words 'up to' and 'projected'. And the five gas plants are named as a headline item, but the source gives no sites, capacities or dates.
Mark
What about the Saudi crude deal?
Mimi
It is a joint intent and a first-step memorandum, with storage expected from the second half of 2027. Nothing is final yet.
Der Puls
- Peak electricity demand could climb from 8.6GW to as high as 13GW by 2031, pressing the grid toward its limits.
- Indonesia has begun cutting gas supplies, a modest share of daily demand but a sharp reminder of exposure.
- Officials warn that resource nationalism during supply crunches could undermine contracts and chill energy investment.
- Up to S$5.3 billion is flowing into transmission substations, cables and distribution upgrades to absorb the load.
- Storage is set to nearly triple past 1GWh by 2030, and a Saudi crude reserve at Jurong Rock Caverns is due to open in late 2027.
On a Monday that opened Singapore's energy week, the minister set out a five-year plan that is less a list of projects than a quiet admission that the island's appetite for power is growing faster than its old machinery can comfortably serve. Chipmaking, data centres and electric transport are pulling demand upward, and the country is answering with gas plants, wider grids, and batteries meant to hold energy in reserve. The same day, Indonesia began trimming its gas flows, a small reduction that nonetheless reminds a small, import-dependent nation how much of its security rests on decisions made beyond its borders. The response, as described, is to build many overlapping defences rather than trust any single one.
On Monday, at the opening of Singapore International Energy Week, Energy and Industry Minister Tan See Leng unveiled a five-year energy infrastructure plan that he called the most significant build-up of the country's energy system in decades. It spans gas-fired generation, the grid, solar, storage and low-carbon electricity imports, and it was born from a simple arithmetic of growth: peak demand stood at 8.6 gigawatts in August and could reach between 9.9 and 13 gigawatts by 2031, driven by semiconductor fabs, data centres and electric vehicles.
The announcement arrived as Indonesia started reducing gas supplies to Singapore, a cut of less than 2 per cent of daily demand. Dr Tan said the country had weathered similar disruptions calmly because of investments made over the years, and he echoed his party's refrain that Singapore could keep calm and carry on. He was also candid that no small island can shield itself from regional or global shocks, pointing to the Strait of Hormuz, and warned that resource nationalism in a crunch could erode contracts and discourage the investment the region needs.
Most of the money goes underground and into wires. Up to S$5.3 billion is planned for the grid between 2025 and 2029, with seven new substations by 2031 and the transmission network expanding from about 7,700km to 9,100km by 2030. Cable tunnels, now around 50km, may more than triple, easing future digging and road works. Storage will grow from roughly 350 megawatt-hours to over a gigawatt-hour by 2030, giving the system a way to absorb surges and release power at peak times, with the regulator inviting industry proposals.
Separately, Singapore and Saudi Arabia announced an intent to store Saudi crude at Jurong Rock Caverns, with operations expected in the second half of 2027, a hedge against disruption that also strengthens Saudi supply in the region.
On Monday, October 26, at the opening of Singapore International Energy Week 2026, Energy and Industry minister Tan See Leng described a five-year energy infrastructure plan as the most significant build-up of the country's energy infrastructure in decades. The plan covers power generation, natural gas, the electricity grid, solar deployment, energy storage and low-carbon electricity imports.
The reason is demand. The Energy Market Authority (EMA) says Singapore's peak electricity demand stood at 8.6 gigawatts as of August. By 2031 it could reach somewhere between 9.9GW and 13GW. EMA attributes the rise mainly to energy-intensive sectors such as semiconductor manufacturing and data centres, along with wider use of electric transport. It added that the pace of growth will depend on when those new developments come onstream. The plan's lead items include five new natural gas-fired power plants, an expanded grid and more storage.
Dr Tan spoke as Indonesia began cutting gas supplies to Singapore over the weekend. The reduction amounts to less than 2 per cent of the country's total daily gas demand. He said Singapore has handled similar disruptions without incident because of measures it has invested in over many years, repeating a line he used after the People's Action Party's conference on Sunday: Singapore can "keep calm and carry on." Households and businesses, he said, can be assured that energy security is always at the top of the government's mind.
He was also frank about limits. Singapore cannot insulate itself from regional or global shocks, he said, citing the crisis in the Strait of Hormuz. In a supply crunch, countries may put their own needs first. He called this resource nationalism particularly concerning if it undermines established contracts, since it raises business risks and deters energy investment. For an importer like Singapore, he said, that is why the country has built multiple lines of defence.
The grid is where much of the money goes. Singapore is projected to invest up to S$5.3 billion (US$4.15 billion) between 2025 and 2029, eleven times the amount in the preceding five years. That supports seven new transmission substations by 2031, up from four in the previous five years. The transmission cable network, which carries high-voltage power from plants to different parts of the island, will grow from about 7,700km to about 9,100km by 2030. The lower-voltage distribution network will be strengthened to handle new sources of supply and demand, such as solar panels and electric vehicle charging.
Singapore is also studying whether it could more than triple its cable tunnels, now about 50km long. Tunnels allow faster grid expansion, easier maintenance access and less frequent and shorter road works for new cables. The extended network would also serve high-growth areas such as Tampines Wafer Fab Park.
Energy storage capacity will rise from about 350 megawatt-hours to just over 1 gigawatt-hour by 2030. Dr Tan said such systems will be critical to the future power system. They can respond quickly to disruptions, and they can store power when network capacity is spare and release it at peak times while upgrades are underway. EMA has issued an Energy Storage Systems Vision and Industry Consultation Paper inviting proposals on technologies, business models and projects that can be deployed commercially at scale. It will gather feedback on rules and constraints that could hinder deployment, develop requirements for how systems operate, including central control where needed, and is seeking interest in an industry-led workgroup.
Separately on Monday, the Ministry of Energy, Trade and Industry and Saudi Arabia's Ministry of Energy announced a joint intent to set up a crude oil arrangement in Singapore. Saudi crude would be stored at the Jurong Rock Caverns on Jurong Island, with operations expected to begin in the second half of 2027. The oil would support Singapore in a disruption and strengthen the resilience of Saudi supply in Southeast Asia. EMA and JTC Corporation signed a memorandum of understanding with Saudi Arabian Oil Company as a first step.
