Question: Who was president when the area where Intrepid Wind Farm is located became a state?

full_context: Document 1: Wind power in Indiana: Wind power in Indiana was limited to a few small water - pumping windmills on farms until 2008 with construction of Indiana's first utility - scale wind power facility, Goodland (phase I) with a nameplate capacity of 130 MW. As of September 2017, Indiana had a total of 1897 MW of wind power capacity installed, ranking it 12th among U.S. states.
Document 2: Indiana: In order to decrease the threat of Indian raids following the Battle of Tippecanoe, Corydon, a town in the far southern part of Indiana, was named the second capital of the Indiana Territory in May 1813. Two years later, a petition for statehood was approved by the territorial general assembly and sent to Congress. An Enabling Act was passed to provide an election of delegates to write a constitution for Indiana. On June 10, 1816, delegates assembled at Corydon to write the constitution, which was completed in 19 days. President James Madison approved Indiana's admission into the union as the nineteenth state on December 11, 1816. In 1825, the state capital was moved from Corydon to Indianapolis.
Document 3: Top of the World Windpower Project: The Top of the World Windpower Project is a 200 megawatt wind farm located near Casper, Wyoming, USA. The project, operated by Duke Energy, was constructed on approximately of land held under long-term lease in Converse County. The Top of the World Windpower Project began operation in 2010.
Document 4: Wind power in the United States: In 2016, Nebraska became the eighteenth state to have installed over 1,000 MW of wind power capacity. Texas, with over 20,000 MW of capacity, had the most installed wind power capacity of any U.S. state at the end of 2016. Texas also had more under construction than any other state currently has installed. The state generating the highest percentage of energy from wind power is Iowa. North Dakota has the most per capita wind generation. The Alta Wind Energy Center in California is the largest wind farm in the United States with a capacity of 1548 MW. GE Energy is the largest domestic wind turbine manufacturer.
Document 5: Iowa: Almost immediately after achieving territorial status, a clamor arose for statehood. On December 28, 1846, Iowa became the 29th state in the Union when President James K. Polk signed Iowa's admission bill into law. Once admitted to the Union, the state's boundary issues resolved, and most of its land purchased from the Indians, Iowa set its direction to development and organized campaigns for settlers and investors, boasting the young frontier state's rich farmlands, fine citizens, free and open society, and good government.
Document 6: Des Moines, Iowa: On September 22, 1851, Des Moines was incorporated as a city; the charter was approved by voters on October 18. In 1857, the name ``Fort Des Moines ''was shortened to`` Des Moines'', and it was designated as the second state capital, previously at Iowa City. Growth was slow during the Civil War period, but the city exploded in size and importance after a railroad link was completed in 1866.
Document 7: Ohio: On February 19, 1803, U.S. President Thomas Jefferson signed an act of Congress that approved Ohio's boundaries and constitution. However, Congress had never passed a resolution formally admitting Ohio as the 17th state. The current custom of Congress declaring an official date of statehood did not begin until 1812, with Louisiana's admission as the 18th state. Although no formal resolution of admission was required, when the oversight was discovered in 1953, Ohio congressman George H. Bender introduced a bill in Congress to admit Ohio to the Union retroactive to March 1, 1803, the date on which the Ohio General Assembly first convened. At a special session at the old state capital in Chillicothe, the Ohio state legislature approved a new petition for statehood that was delivered to Washington, D.C. on horseback. On August 7, 1953 (the year of Ohio's 150th anniversary), President Eisenhower signed a congressional joint resolution that officially declared March 1, 1803, the date of Ohio's admittance into the Union.
Document 8: Intrepid Wind Farm: The Intrepid Wind Farm consists of 107 wind turbines, located in Sac and Buena Vista counties in north-west Iowa, has a generating capacity of 160.5 megawatts of electricity. The wind power project is MidAmerican Energy Company’s first owned and operated wind generation facility and became operational on December 31, 2004.
Document 9: History of Idaho: When President Benjamin Harrison signed the law admitting Idaho as a U.S. state on July 3, 1890, the population was 88,548. George L. Shoup became the state's first governor, but resigned after only a few weeks in office to take a seat in the United States Senate.
Document 10: Tatanka Wind Farm: The 180 MW Tatanka Wind Farm, is located in Dickey County and McIntosh County, North Dakota, and McPherson County, South Dakota. It is the largest wind farm in North and South Dakota and generates enough renewable energy to power more than 60,000 U.S. homes.
Document 11: Wind power in Iowa: Wind farms are most prevalent in the north and west portion of Iowa. Wind maps show the winds in these areas to be stronger on average, making them better suited for the development of wind energy. Average wind speeds are not consistent from month to month. Wind maps show wind speeds are on average strongest from November through April, peaking in March. August is the month with the weakest average wind speeds. On a daily cycle, there is a slight rise in average wind speeds in the afternoon, from 1 to 6 p.m. Estimates by the National Renewable Energy Laboratory (NREL) indicate Iowa has potentially 570,700 Megawatts of wind power using large turbines mounted on 80 meter towers. Iowa ranks seventh in the country in terms of wind energy generation potential due to the strong average wind speeds in the midsection of the U.S. The Iowa Environmental Mesonet distributes current weather and wind conditions from approximately 450 monitoring stations across Iowa, providing data for modelling and predicting wind power.
Document 12: Altamont Pass wind farm: The Altamont Pass wind farm is located in the Altamont Pass of the Diablo Range in Northern California. It is one of the earliest wind farms in the United States. The first wind turbines were placed on the Altamont in the early 1980s by Fayette Manufacturing Corporation on land owned by cattle rancher Joe Jess. The wind farm is composed of 4930 relatively small wind turbines of various types, making it at one time the largest wind farm in the world in terms of capacity. Altamont Pass is still one of the largest concentration of wind turbines in the world, with a capacity of 576 megawatts (MW), producing about 125 MW on average and 1.1 terawatt-hours (TWh) yearly. They were installed after the 1970s energy crisis in response to favorable tax policies for investors.
Document 13: Minnesota: In 1762 the region became part of Spanish Louisiana until 1802. The portion of the state east of the Mississippi River became part of the United States at the end of the American Revolutionary War, when the Second Treaty of Paris was signed. Land west of the Mississippi River was acquired with the Louisiana Purchase, although a portion of the Red River Valley was disputed until the Treaty of 1818. By the late 1700s, the North West Company had established the post of Fort Charlotte at the Lake Superior end of the Grand Portage, until moving 50 miles northeast to Fort William in 1803. In 1805, Zebulon Pike bargained with Native Americans to acquire land at the confluence of the Minnesota and Mississippi rivers. The construction of Fort Snelling followed between 1819 and 1825. Its soldiers built a grist mill and a sawmill at Saint Anthony Falls, the first of the water-powered industries around which the city of Minneapolis later grew. Meanwhile, squatters, government officials, and tourists had settled near the fort. In 1839, the army forced them to move downriver and they settled in the area that became St. Paul. Minnesota Territory was formed on March 3, 1849. The first territorial legislature (held September 2, 1849) was dominated by men from New England or of New England ancestry. Thousands of people had come to build farms and cut timber, and Minnesota became the 32nd U.S. state on May 11, 1858. The founding population was so overwhelmingly of New England origins that the state was dubbed "the New England of the West".
Document 14: Jersey-Atlantic Wind Farm: The Jersey-Atlantic Wind Farm in Atlantic City, in Atlantic County, New Jersey, is the first coastal wind farm in the United States and the first wind farm in New Jersey. It became operational in March 2006 and consists of five 1.5 MW turbines built by General Electric. Each wind turbine reaches a height of .
Document 15: History of Texas (1845–1860): The Republic of Texas had formed in 1836, after breaking away from Mexico in the Texas Revolution. The following year, an ambassador from Texas approached the United States about the possibility of becoming an American state. Fearing a war with Mexico, which did not recognize Texas independence, the United States declined the offer. In 1844, James K. Polk was elected the United States president after promising to annex Texas. Before he assumed office, the outgoing president, John Tyler, entered negotiations with Texas. On February 26, 1845, six days before Polk took office, the U.S. Congress approved the annexation. The Texas legislature approved annexation in July 1845 and constructed a state constitution. In October, Texas residents approved the annexation and the new constitution, and Texas was officially inducted into the United States on December 29, 1845.
