Two Pratt & Whitney generators with a combined capacity of 45 megawatts were turned on today, state-run Unified said in an e-mailed statement today. Another eight generators will give Moscow 225 megawatts of new capacity and help avoid blackouts during peak consumption, OAO Unified Energy said. Power use in the Russian capital surged 6% last year, versus the 4.2% national average. Pratt & Whitney is a unit of United Technologies Corp. (Bloomberg)
