project benefits
The Adams County Rd 550 Connector will achieve the full benefits of the Illinois Rivers Project which includes:

  • Improve electric system reliability
  • Improve access to renewable energy sources
  • Support the State of Illinois in meeting its Renewable Portfolio Standard (RPS)
  • Improve access to lower-cost electricity by reducing transmission congestion

Why We Build Transmission: We depend on reliable electricity every day. The electric transmission grid on which we rely is comprised of a large network of interconnected transmission lines. This network is the backbone to delivering power to our homes, schools and businesses.

In order to bring power from interspersed generators to you, transmission lines deliver electricity to substations, which reduce the electricity to lower voltages so it can travel through the distribution system to your home or business.
