As the economy goes back to pre-pandemic levels, we can expect more reduced generation and consumption. It is expected for renewable energy to grow as petroleum prices are expected to increase. This may mean, besides public policy issues going on in Puerto Rico, possible higher energy costs. The Energy Bureau in Puerto Rico approved a 3.1% increase of cents per kWh solicited by the Puerto Rico Electric Power Authority (PREPA). This may be a sign of future increases to come.
