The excerpts reference a variety of regulatory dockets and filings before the South Carolina Public Service Commission, highlighting several areas of growth for Dominion Energy South Carolina and the broader utility sector. The main areas of growth identified include:

- Renewable Energy and Power Purchase Agreements: Multiple dockets concern the approval and management of power purchase agreements with solar and other renewable facilities, indicating a focus on expanding renewable energy capacity and integrating these resources into the grid. Key considerations include contract approval, requests for confidential treatment, and compliance with state renewable energy procurement laws 1, 1.

- Demand Side Management (DSM) Programs: The filings mention annual updates and modifications to DSM programs, including associated rate riders and requests for rate increases or decreases. Growth in this area is tied to regulatory approval of program updates and periodic adjustments to cost recovery mechanisms 1, 1, 1.

- Grid Reliability, Stability, and Infrastructure Upgrades: Dockets address proposals to review grid reliability and stability, the retirement of coal plants, and construction of new transmission lines and substations. Considerations include environmental compatibility, public convenience and necessity, and compliance with specific state code requirements 1, 1.

- Interconnection Queue and Distributed Generation: Semi-annual interconnection queue reports are filed as utilities manage the process for connecting new distributed generation projects. Key issues involve procedural compliance, queue management, and adherence to commission orders on generator interconnection 2, 1.

- Regulatory and Legislative Compliance: Ongoing reviews of state regulations, such as those related to electric and gas systems and the implementation of federal legislation like the Infrastructure Investment and Jobs Act, also shape areas of utility growth. Considerations here focus on regulatory adaptation, stakeholder input, and securing grants or funding for infrastructure improvements 1, 1.

Each area requires careful attention to regulatory approval processes, stakeholder engagement, cost recovery, and compliance with state and federal requirements.
