Increases System Capacity by 2Q7 conservative furnace-heat release, and even (he boiler steaming capacity--will all be found in plants making up the largest single statistical group in the notional expansion program. We can conclude that Blackhawk represents the trend of sound central-station engineer ing practice today. Sarvlee Ateal Wisconsin Power and Light Co serves an arco in south cen tral Wisconsin that runs about 180 miles north and south and 120 miles cost and west. Generating capacity prior to the Blackhawk installation waa 42,796 kw in hydro plants and 80,270 kw In steam plants. Annual energy received over interconnections ran about 11% of total generation. Placing Black hawk in service January 1947 raised (he system capacity by about 20%. Since thia new extension follows the unit-design basis it reflects the increas ing reliability of this class of- equip ment that has developed over the years. Blackhawk Generating Station con sists of a 25,000-kw extension and the former 10,000-kw Beloit Station in Be loit, Wisconsin. The plant is located on the extreme southern end of the system. A 66-kv line' is under'con struction running east and west from Beloit, reinforcing the present trans mission outlets from the plant: Sargent ft Lundy.Chicogo, designed the extension; a second'25,000-kw unit now on order will start in March 1950. This plant and (ho other principal sta tions--Edgewoter, at Sheboygan on Lake Michigan, and the hydro stations at Prairie du Sac and Kllbourn-- 0)l| 65
