DES MOINES, Iowa (AP) — An Iowa power cooperative says it plans to add solar panels to the state to generate another source of energy.

Central Iowa Power Cooperative said Thursday it plans to have the panels operational by the end of 2016. They're currently accepting bids for the work, which will determine where the panels are located and how much will be spent.

CIPCO says the panels will be located on the ground. Officials expect to use at least 30 acres of land for the project, which may be split into several sites.

Karen Morrow, a CIPCO spokeswoman, says generating solar energy is another way for the cooperative to provide clean electricity. Officials say they use resources including wind and hydroelectric.
