The Kansas Corporation Commission is challenging Westar Energy's interstate electric transmission rates, saying they are "unjust and unreasonable."
The KCC filed a complaint with the Federal Energy Regulatory Commission this week. It says Westar's 11.3 percent cost of equity should actually be almost two full percentage points lower at 9.37 percent. The KCC also says Westar rates could be lowered by almost $16 million with a reduction in transmission rates.
Westar, meanwhile, says it made infrastructure investments the past and it's concerned the KCC push to lower rates may "cause Kansas to fall behind."
