Lubbock Power and Light will accept new bids for plans to generate power in 2019.
On Monday afternoon, the electric utility board voted to throw out the old proposals.
A law firm reviewed the old plans after allegations of bid rigging and said they found no evidence of wrongdoing.
But, Board Chairman Greg Taylor says they were left with out-dated estimates.
"We felt it was best to get really fresh numbers. That RFP process resulted in figures that are nearly a year old," Taylor said.
Taylor says the new plans will include new options, including where to place a possible power plant, and where to get water to cool it.
