The CEO of the biggest power company in the US had a problem. A Democratic state senator was proposing a law that could cut into Florida Power & Light's (FPL) profits. Landlords would be able to sell cheap rooftop solar power directly to their tenants bypassing FPL and its monopoly on electricity. "I want you to make his life a living hell ... seriously," FPL's CEO Eric Silagy wrote in a 2019 email to two of his vice-presidents about state Senator José Javier Rodríguez, who proposed the legislation. Within minutes, one of them forwarded the directive to the CEO of Matrix, LLC, a powerful but little-known political consulting firm that has operated behind the scenes in at least eight states. Rodríguez was ousted from office in the next election. Matrix employees spent heavily on political advertisements for a candidate with the same last name as Rodríguez, who split the vote. That candidate later admitted he was bribed to run. Hundreds of pages of internal documents " which are only coming to light now because Matrix's founders are locked in an epic feud " detail the firm's secret work to help power companies like FPL protect their profits and fight the transition to cleaner forms of energy. The Matrix saga illustrates the political obstacles policymakers and experts face as they attempt to cut climate pollution from the power sector. Matrix affiliated groups have also worked to advance power companies' interests in Arizona, Louisiana, Mississippi, Georgia, and in front of the Environmental Protection Agency, public records show.
