Puerto Rico Governor Jenniffer González has pledged to boost the amount of electricity available to power the US territory as chronic outages persist, angering and frustrating many across the island.

She said a bidding process to install 3,000 megawatts of additional power-generation capacity is under way and will likely be completed by late summer. In addition, she announced that nearly 1,000 megawatts will be added to the system in the coming months as crews work to repair and modernise various power plants.

González noted that 100 megawatts provide sufficient energy for 60,000 families.
