HCH, consider if you will the true test of an efficient power plant, it's a little equation that calculates something called heat rate. In lay terms, it's the equivalent of "gas mileage". This coupled with the real costs of maintenance equals true efficiency, not advertised efficiency. MEA's new plant likely will not land in the coveted seat of most efficient. CEA's SPP and ML&P's new combined cycle plants would easily take the fossil fuel fired title.
The real problem on the rail belt is that the large power producers in the state will not swallow their arrogance and pride long enough to work together to save the rate payers money. Unfortunately, unless you are extremely political and influential, your small insignificant voice will be completely ignored by the board members with personal political adjendas and self appointed puffed up utility officials. If this situation doesn't change, there is no hope. 
Remember, always consider the real numbers, they don't lie!!!
