General Electric Co (GE.N) shook up its ailing power business again on Monday, naming a CEO for its new gas-power division and bringing a veteran GE executive back from retirement to help. The changes mark another step in new GE Chief Executive Officer Larry Culp’s urgent effort to reduce heavy debt and restore profits at the 126-year-old, Boston-based conglomerate, according to Reuters.

It also highlights the problems at GE Power. Culp reorganized the division three weeks ago, separating its gas-turbine business from units that make coal- and nuclear-fueled power plants, power grids and other equipment. “One of my top priorities is positioning our businesses to win, starting with GE Power,” Culp said in a statement.

GE stock was down 1.1 percent at $7.94 in afternoon trading. The stock has fallen 56 percent this year.

GE picked John Rice, a 39-year GE veteran who once headed its energy unit and retired last year, as chairman of gas power, reporting to Culp. Rice’s “knowledge of GE’s gas customers and management experience” will help him provide “mentorship” to the new gas power leaders and “position this business and the team for success,” GE said.

GE also named Scott Strazik, CEO of GE Power’s repair and maintenance business, to be CEO of Gas Power, overseeing both equipment sales and services. GE Power’s current Chief Executive Officer, Russell Stokes, will become CEO of other power activities. Strazik and Stokes also will report to Culp, GE said.
