Alliant Energy’s grid of the future: Strategic telecommunications (fiber) will play a key role

Telecommunication is a foundational element of the Grid Modernization Program 

Alliant Energy’s Grid Modernization Program is transforming the distribution grid into a digital system with continuous two-way flow of electricity and information. The projects within the program leverage new technologies, tools, data and practices to meet emerging customer requirements. This will lead us toward our Grid of the Future.

Future electric distribution will require secure two-way flow of increasing amounts of data. That’s where our Strategic Telecommunications Project comes in. We’re replacing leased third-party telecommunications capacity and installing our own fiber optic networks.

Fiber optic cable is the preferred network backbone because the grid of the future will be far more data intensive. Sensors, smart meters, fault interrupters and other digital devices are transforming how customers receive, use and generate energy. This means massive amounts of information will need to flow back and forth smoothly, securely and continuously.

The following map shows the core fiber ring we’re installing between now and the end of 2020.

Our fiber networks will create strong digital highways. They will also improve connectivity for the rural portions of our service area, where delivering consistent high-speed online access has been a challenge. Future project phases will use wireless technology to expand the fiber network and bring connectivity to an increasing number of distributed grid devices.
