United Technologies said it had agreed to acquire a 49.5 percent stake in Clipper Windpower, a struggling California-based turbine maker, for $270 million to expand in alternative energy sources. Clipper began to look for investors earlier this year as customers delayed turbine orders while defects in some older turbines needed repairs. United Technologies said the deal, which was announced Wednesday, “allows U.T.C. to expand its power generation portfolio and enter the high-growth wind power segment.” Stock in United Technologies, which is based in Hartford, Conn., rose $1.47, or 2 percent, to $69.40 a share.
