Heartland faces challenges from EPA
Emissions goals pose challenges; electric rate increases likely
The provider of about half of the electricity used by Madison’s electric utility customers has concerns about reaching the carbon-dioxide emissions reductions proposed by the EPA earlier this summer.
John Knofczynski, engineering manager at Heartland Consumers Power District, offered a presentation on Thursday to fellow members of the municipal Electric Advisory Committee that outlined the challenges one of Madison’s electricity suppliers faces if the current federal proposals remain the same.
Knofczynski warned that the current options for meeting a 35-percent reduction of South Dakota’s carbon dioxide emissions would mean a major restructuring of HCPD’s electricity supply and most likely higher costs to consumers.
Knofczynski said the EPA had an overall goal to reduce carbon-dioxide emissions across the nation by 30 percent less than 2012 levels. The EPA wants to reach that goal by 2030, but federal officials also have interim target levels that they want the states to reach by 2020.
The EPA has proposed that the states use four building blocks in the reduction plans: heat-rate improvements at existing power plants; substituting coal-based electricity with natural gas combined-cycle electricity generation; substituting renewable electricity generation; and demand-side (consumer) energy efficiency measures.
Knofczynski said that South Dakota only has one natural gas generation plant currently available, the Deer Creek Station owned by Basin Electric Power Cooperative. He said the Deer Creek Station would need to operate at more than a 70-percent capacity factor to offset generation losses from the coal-fired Big Stone Power Plant.
He also said under current EPA policies, electricity providers will not receive any credit for supporting renewable energy production that was active before the carbon-dioxide reduction policies go into effect.
Knofczynski told the advisory committee members that the EPA’s building blocks offered little in practical solutions to South Dakota consumers.
In his presentation, Knofczynski listed Heartland’s three primary electric power resources:
- Whelan Energy Center Unit 2 near Hastings, Neb., which has a 225-megawatt (MW) output from its coal-fired generation plant. HCPD has 35-percent ownership equaling 82 MW; however EPA officials gave Nebraska a 26-percent reduction target.
- Laramie River Station near Wheatland, Wyo., a three-unit, 1,710-MW coal-fired plant in which HCPD has a 3-percent share equaling 51 MW. Wyoming has a 19-percent reduction target, but Laramie Station is also currently managing a regional haze mandate made by federal officials.
- Wessington Springs Wind Energy Center in South Dakota, consisting of 34 wind turbines providing 51 MW in total capacity. Heartland has purchased the full output from the wind farm since it went into service in February 2009.
