How companies in this sector earn

How do Utilities companies make money?

  • Regulated utilities charge customers rates that a state commission approves, which are meant to cover costs and allow a return on what the utility has invested.
  • Power producers sell electricity on wholesale markets or under long contracts, called power purchase agreements, with buyers such as utilities and large companies.
  • Some companies build and run power plants or sites for one large customer and charge for the power and capacity used.
  • Building plants and power lines takes large sums up front, so borrowing and interest are major costs alongside fuel.

Who regulates it

Federal Energy Regulatory Commission (FERC), for wholesale power and transmission · State public utility commissions, which set the customer rates of many utilities · Nuclear Regulatory Commission (NRC), for nuclear plants and new reactor designs · Environmental Protection Agency (EPA), for emissions from power plants

What moves results across the sector

  • Electricity demand, including from data centers, which the companies describe in their filings.
  • Regulatory approvals: rate decisions, plant licenses and connections to the grid.
  • Interest rates and borrowing, because plants and power lines are built largely with debt.
