SMMPA owns 41% (362 MW) of Sherco 3 (884 MW), the newest, most efficient coal-fired electric generating facility in the entire Midwest region. Sherco 3 provides over 78% of the energy needs of homes and businesses in SMMPA member communities. This plant's state-of-the-art air quality control technology uses the dry scrubbing system that removes up to 90% of the sulfur dioxide and 99% of the particulates from the flue gases. Approximately 30% of the $1.072 billion construction budget was used on environmental controls. SMMPA and its members are finding a better way to reduce impact on air quality.
