Our Projects

We understand that our customers' needs are constantly changing and the energy industry is constantly evolving. We are working on several major projects that will help us continue to serve safe and reliable energy well into the future.

We continue to focus on investments to address aging infrastructure, enhance reliability of our system, add capacity, and meet compliance requirements. In 2020, we spent $403.3 million on capital projects replacing existing assets and adding new assets to our system in order to enhance and maintain our energy system. This level of investment was up approximately 24% over 2019.
