Genera PR said on Friday that the Central San Juan power plant is running on diesel after a natural gas supply interruption.[^1]

Genera PR generates about 60% of all electrical power in Puerto Rico.[^2] The company did not state how long the diesel run would last or what the gas interruption changes for generation on the island.

The outage note is the concrete item here. The read on what it costs to burn diesel instead of gas is not something the facts carry, so it stays off the page until Genera PR puts a number to it.
