After considering sites in Manchester, Coventry, Bradford and Leicester, it was an offer from Derby's council of cheap electricity that resulted in the decision to acquire a 12.7 acres (51,000 m) site on the southern edge of that city . The new factory was largely designed by Royce, and production began in early 1908, with a formal opening on 9 July 1908 by Sir John Montagu . The investment in the new company required further capital to be raised, and on 6 December 1906 £ 100,000 of new shares were offered to the public . In 1907, Rolls - Royce bought out C.S. Rolls & Co . (The non-motor car interests of Royce Ltd. continued to operate separately .) </P>
