The document summarizes CESGA's energy efficiency plan (CEEP) to reduce costs and energy consumption. Before the plan, an analysis found opportunities to improve systems like climatization, lighting, and computing. The plan outlined activities like monitoring upgrades, increasing temperature setpoints, closing cold aisles, and server consolidation. Metrics like PUE were used to measure impact. Initial results included savings from mechanisms like power management, free cooling optimization, and temperature decreases from closed cold aisles. Ongoing work focuses on memory, job scheduling, and renewable energy.

5. CESGA MISSION STATEMENT
To provide high performance computing and advanced
communications resources and services to the
scientific community of Galicia and to the Spanish
National Research Council (CSIC), as well as, to
institutions and enterprises with RTD activity.
To promote high quality research in Computational
Science in close collaboration with the research
community from Galicia as well as from other
regions or countries all over the world; contributing in
this way to the advancement of science, to transfer
technology to industry and administrations, and
as consequence, to the wellbeing of society as a
whole.
