More people are embracing solar, battery storage, and other onsite sources of energy for Distributed Generation (DG). By doing so, they can reduce their energy usage and save money on their electric bill. With DG, electricity comes from many small sources at an individual’s home or business. Along with solar and wind, natural gas-fueled micro-turbines, diesel-fueled engines, batteries, and landfill gas are common components of DG. Unlike emergency generators or other off-grid systems that serve an isolated load and are not connected to the Oncor grid, DG sites are interconnected so they can function in parallel with the Oncor grid or separately. DG systems typically have a capacity of 10 megawatts (MW) or less, and are connected to the grid with voltage less than 60 kilovolts (kV). We work cooperatively with customers—or customers' designated representatives—to ensure a safe and reliable interconnection of DG sites to our system.
