Ottawa Street Power Station
Ottawa Street Power Station is a former municipal electric and steam utility generating station for the Lansing Board of Water and Light in Lansing, Michigan, located on the Grand River in the city's central business district currently being redeveloped as corporate headquarters for the Accident Fund Insurance Company of America.

Design and construction
The engineering design of the plant was by Ralph C. Roe and Allen Burns of the firm of Burns and Roe, and represented an improvement over the design of the Bremo Station in Virginia, which the two had designed while employed at Electric Management and Engineering Company. The architectural design was by Edwyn A. Bowd of Bowd and Munson. Construction began in 1937 and was completed in 1939, at a cost of $4 million, with formal dedication the following year. Major additions were completed in 1946. The 176-foot (54 m) tall Art Deco step-back structure sits on a polished black granite water table, with an intricate exterior design of multicolor brick. The design symbolizes the combustion of coal, and graduates from dark purple at the base through reds and orange in the middle, to light yellow at the top, alternating with bands of limestone, and with limestone parapets and trim. The Ottawa Street station was praised for its engineering and architecture in trade publications of the day, and immediately became the city's preeminent Art Deco landmark. Bowd subsequently designed a number of other prominent Art Deco and Streamline Moderne buildings in the Lansing area, including the J.W. Knapp Company Building.

Operating History
The Ottawa Street station provided electricity and steam to the downtown Lansing area from 1939 through the late 1980s. By 1971, improvements at the Board of Water and Light's Eckert Station permitted the Ottawa Street Station to operate as a backup station for electric generation. It continued to provide steam service into the 1980s. In 1984, the Board of Water and Light's Eckert Station began providing steam service, initially as a backup to the Ottawa Street Station, but eventually as the primary steam service source. As equipment became obsolete, it was removed from the Ottawa Street Station, and ultimately it was decommissioned in 1992 for electric and steam. In 2001, a portion of the station was renovated to provide chilled water service for air conditioning. It continued to operate as a water chilling plant until September 2009, when the Board of Water and Light completed a new chilled water plant in downtown Lansing.

Following decommissioning, the City of Lansing explored various options for redevelopment of the Ottawa Street Station. In 2007, it was sold to be redeveloped as corporate headquarters for the Accident Fund Insurance Company of America. Massive renovations to convert the plant to an office building are currently underway by The Christman Company, with completion of the entire 7-acre (28,000 m 2) office campus scheduled for the first quarter of 2011.
