A major report on future options for energy generation and options is nearing completion.
The study will provide technical and economic evaluations for various energy scenarios so the municipal utility can "supply an affordable, reliable, and environmentally friendly supply of capacity and energy for the next 20 years."
The master energy plan will recommend a preferred energy portfolio, project energy demand, explore energy efficiency options and make recommendations on generating capacity and staffing levels.
The City Council received a preliminary report in July.
The most significant issue the master energy plan is expected to address is the future of the city-owned Blue Valley power plant.
The city-owned power plant has three steam-generating units which currently use natural gas. The generators date back to 1958 and 1965.
The Blue Valley power plant generated only 1.73% of all IPL energy in 2016.
The master energy study is being conducted by Burns and McDonnell at a cost of $325,000.
Indy Energy and three other groups - Renew Missouri, the Sierra Club and the Natural Resources Defense Council - are requesting an opportunity for public comment and review of a major IPL master energy study which is nearing completion.
The four groups submitted a letter making the request.
