The Greek government created the Public Power Corporation (PPC) in 1950 to implement a national electric energy policy and utilise domestic energy resources. Today, PPC provides 93 percent of the power capacity in Greece, generated by lignite, fuel oil, hydro-electric, and natural gas power plants and wind and solar energy parks. PPC is the largest business in Greece in terms of assets, with 98 power plants and 2008 revenues of €5.82 million.

As Head of Office Systems in the PPC Information Technology department, Ioannis Symeonidis oversees 4,200 desktop and portable computers that are shared by 7,500 users.

Business needs vary significantly among PPC departments, so the IT staff needed to create and maintain multiple software images and service many types of hardware. Deploying new computers and applications involved a great deal of manual work, which delayed deployments and impaired the company’s ability to make new employees productive and meet new business needs. The utility’s large computer fleet not only was expensive to maintain but gobbled loads of kilowatts.

PPC decided to move their operations on Windows 7. “We saw the deployment of Windows 7 as a great opportunity to revisit and update our desktop management procedures and reduce IT labor costs,” Symeonidis says. With the assistance of Microsoft Services, PPC deployed Windows 7 Enterprise to a test environment of 20 computers, and then to 200 more.

Thanks to the power management efficiencies of Windows 7, PPC will be able to reduce energy consumption. “We believe that Windows 7 will help us reduce overall power consumption through performance optimizations, idle-resource utilization, and device power management,” Symeonidis says. “Windows 7 has important features that help reduce wasteful power consumption, thus helping us be more environmentally conscious, which is important to us as a utility.”
