Puerto Rico's Energy Bureau approves a record 33.86-cent power rate lasting through at least December

The Energy Bureau's figures reconcile. At 800 kWh, the approved 5.28-cent increase ^[7] works out to $42.24 a month ^[3], and 800 kWh at the new 33.86-cent rate comes to $270.88 ^[4]. Both are within a dollar of the bureau's own example ^[2]. In that example the whole increase is a per-kWh charge, so it rises with consumption. The bureau granted more than 0.72 cents per kWh less than Luma sought ^[5], after Luma said the increase would bring it no additional revenue and would only cover higher costs ^[5].

Luma's explanation mixes seasonal causes with lasting ones. "The difference is driven by higher energy consumption due to high summer temperatures, rising global oil prices resulting from the conflict in the Middle East", Luma said, also citing "greater use of customer batteries, and the need to rely on more expensive fuel when power plants do not generate enough electricity" ^[6]. One expensive fuel in use now is diesel. The north-coast plants that New Fortress Energy supplies with natural gas are burning it because a gas vessel has been kept out of San Juan Bay for two weeks over its size, a case still in court ^[10]. Summer heat and a blocked ship can clear within months. The fuel mix will take far longer to change: in 2024 petroleum was 63% of the island's energy use, natural gas 31%, coal 5% and renewables 1% ^[15], so 99% came from fossil fuels ^[7].

A skeptic would take Luma at its word: if the company earns nothing extra, the rate is a fuel pass-through that unwinds once diesel use ends. The answer is that the cost base itself is in dispute. The bureau is investigating about $19 million that Luma said it paid for gas quantities that officials say exceeded what Genera PR, the generation operator, "ultimately needed or could receive" ^[11]. Add the $17.6 million already kept off bills, and $36.6 million of fuel spending is excluded or under review ^[6]. "Fuel costs must not be automatically passed on to the consumer simply because they were incurred or billed," the bureau said ^[9].

Over the decade, the larger variable is who operates the grid. Luma and Genera PR hold their contracts while the state-owned Electric Power Authority tries to restructure more than $9 billion of debt ^[14], and the governor's effort to remove Luma sits in litigation ^[13]. The grid was already weak from decades of thin maintenance and investment when Hurricane Maria, a Category 4 storm, struck in 2017 ^[16].

For an employer, the choice this quarter is whether to absorb part of the increase for island staff, against a rate fixed until at least December 31 ^[3]. The trade-off is timing. An allowance set now is easy to justify, and I'd expect it to be hard to withdraw in January whatever the next rate turns out to be. Facility budgets are harder to set, because the AP report gives residential figures and does not include commercial tariffs ^[2][4].
