It turns into clearer how Puerto Rico can obtain its objective of acquiring 100% of its electrical energy from renewable vitality sources by 2050.
In the midst of a two-year examine by the federal authorities, referred to as PR100, researchers concluded that the island has far more renewable vitality potential than it wants. The report was launched on Monday. The researchers discovered that there’s a desire amongst many residents for “distributed vitality,” which is produced near the place it’s used. Rooftop photo voltaic panels are the most typical instance of that.
“We’ve got confirmed that these methods are immune to hurricane winds, and that they will present sturdy vitality, inside hours after the storm,” stated Agustín Carbó, Director of the Division’s Puerto Rico Grid Modernization and Restoration Crew of Power. In keeping with him, the present system of smaller, centralized and huge energy crops will take longer to revive electrical energy to the complete island, particularly in distant and mountainous areas.
Final yr the DOE’s Nationwide Renewable Power Laboratory, with funding from the Federal Emergency Administration Company, started finding out choices to transition the island to 100% renewable vitality by the yr 2050. The objective is to construct an electrical energy system. stronger in opposition to future storms, which local weather change analysis exhibits will probably be larger and extra highly effective.
The plan is to modify from imported fossil fuels – petroleum, pure gasoline and coal – to cleaner sources corresponding to photo voltaic and wind. One other objective is to make electrical energy cheaper. The island’s electrical energy charges are about twice as excessive as common charges throughout the US The federal examine is anticipated to be accomplished by the top of this yr.
4 completely different situations have been modeled to fulfill Puerto Rico’s targets – all together with extra rooftop photo voltaic mixed with battery storage. First is the give attention to putting in distributed vitality in buildings the place the house owners can then get the monetary advantages of producing electrical energy. The second focuses on essential companies, corresponding to hospitals, fireplace stations and grocery shops. The third consists of prioritizing deployment in distant and low-to-moderate earnings households to distribute advantages pretty. The final possibility is to put in photo voltaic panels on as many different roofs as doable.
Even earlier than all of the photo voltaic panels are put in, the examine’s authors say the island wants extra electrical energy era.
“Vital extra era capability is clearly wanted instantly to enhance reliability, which is a matter that everybody in Puerto Rico is fighting after Hurricanes Maria and Fiona,” stated Carbó, who beforehand chaired the Puerto Rico Power Fee. . He says fossil fuels are nonetheless wanted within the quick time period because the island works to succeed in its 100% renewable objective.
The Division of Power and FEMA gathered enter for the examine with an advisory panel of practically 100 folks and 50 public, personal and nonprofit organizations.
“For too lengthy, Puerto Ricans have lived in an antiquated and costly electrical energy system the place pointless limitations and lengthy delays have prevented essential enhancements,” stated the Secretary of Power. Jennifer Granholm in a written assertion accompanying a progress report on the examine.
Puerto Rico’s grid collapsed in 2017 after Hurricane Maria hit the island, killing not less than 3,000 residents. Months later crews struggled to revive manufacturing capability and rebuild transmission strains. After years of discontent over mismanagement and corruption within the US territory’s public energy firm, the Puerto Rico Electrical Energy Authority, was privatized.
In September, Hurricane Fiona introduced greater than 30 inches of rain in some areas and knocked out energy on the island once more. There may be widespread discontent with the personal firm, LUMA, which the federal government awarded a $1.5 billion contract to function the grid.
