Utilities invest in infrastructure to ensure energy service is safe, reliable, and available 24/7. Maintaining power plants, pipelines, power lines, and modern grid technology requires significant long-term investment. Because these projects affect customer bills, major investments must be reviewed and approved by state regulators to ensure they are necessary and cost-effective. By investing in infrastructure utilities are also working to improve reliability and prevent outages. When the grid has the newest technology available it will be able to withstand more inclement weather and demand.
