The Grid Transformation Plan consists of projects that work together to improve grid reliability and security. Many of these projects involve work at electric substations.
Voltage islands are single-transformer substations which serve customers and don’t have available backup transformers to pick up the electric load in the event of a failure. Mitigating voltage islands means adding additional transformers to current single-transformer substations. This brings redundancy to the grid and reduces outage lengths.
We are modernizing distribution stations by upgrading certain components that will improve reliability, maintain voltage stability, and increase overall visibility of grid operations. This will help reduce outage response times and integrate renewable energy resources onto the grid.
We are enhancing physical security at substations to mitigate emerging threats to the energy sector and protect from cyber and physical attacks.
