The Public Service Commission in Puerto Rico oversees the rates and service quality of privately owned utilities operating in the state, including electric, natural gas, water, and telecommunications providers. Puerto Rico's commission conducts formal rate proceedings, investigates consumer complaints, and issues orders that affect millions of utility customers statewide.

Utility customers in Puerto Rico who have unresolved billing disputes or service complaints should first attempt to resolve the issue directly with their utility company, then file a formal complaint with the Puerto Rico Public Service Commission if the issue remains unresolved after exhausting the utility's internal complaint process.

Utility customers in Puerto Rico can visit the Public Service Commission's website to review current utility tariffs, track pending rate cases that may affect their bills, and submit online consumer complaints. Many commissions in Puerto Rico also operate consumer assistance hotlines that can help residents understand their utility rights and navigate the complaint resolution process.
