From Oil to Power: Pemex’s Plan to Rewire Mexico’s Grid

Mexico’s state oil giant is making a calculated bet: build electricity where it already burns fuel. By 2030, Pemex plans three high-efficiency cogeneration plants—Tula (up to 794 MW), Salina Cruz (up to 728 MW), and the Cangrejera petrochemical complex (up to 900 MW)—for a combined 2,422 megawatts and about 51 billion pesos in investment.

The plants, developed with the Federal Electricity Commission, will feed steam and power to refineries first and sell any surplus into Mexico’s wholesale market. The story behind the story is about control, costs, and reliability.

Mexico’s power-sector plan projects Pemex’s share of national generation rising from almost nothing to roughly 4.6 percent by 2030, contributing to a larger goal: a majority share of generation held by state firms by decade’s end.

For Pemex, on-site power is not just strategy—it’s survival economics. Company leaders say operating costs are falling, helped by a simpler tax regime and tighter spending, and cogeneration promises further savings by turning refinery heat into electricity rather than letting it dissipate.

Cogeneration is a straightforward idea with outsized impact: use the same fuel to make both electricity and industrial steam. In refineries, that can reduce waste, stabilize operations, and cut dependence on the grid.

Done at scale, it also puts new megawatts close to heavy demand centers—exactly where Mexico’s system strains most when refineries ramp up or the grid tightens.

Pemex Moves Into Power Generation

There is a broader pivot here. Pemex describes itself as moving from an oil company to an energy company, with exploratory lines in hydrogen, biofuels, and even lithium recovery from oilfield brines.

Whether those side bets mature, the immediate, concrete shift is into power—an area where the state wants more say over what gets built and where.

For readers outside Mexico, the stakes are clear: these plants could lower Pemex’s costs, harden critical industrial sites against outages, and tilt Mexico’s electricity mix further toward public ownership.

What to watch now are timelines, execution, and whether promised efficiency gains materialize fast enough to relieve pressure on both the grid and Pemex’s balance sheet.
