NRG Energy Center Minneapolis
A history of growth, reliability and efficiency.
At NRG Energy Center Minneapolis the growth of the system, in many ways, has mirrored the growth of downtown Minneapolis. Today, the system serves more than 100 buildings over 130 downtown blocks – all benefiting from efficient, reliable, environmentally sound heating and cooling. That's a need as relevant today as it was 40+ years ago.
One system. Many benefits.
From NRG's strategically located plants around downtown, chilled water and steam is piped to buildings yielding numerous benefits for the customer
- Reliability – a heating and cooling system every customer can count on with a reliability track record of 99.9999%
- Efficiency – centralized plants serving many buildings is inherently more efficient than each building having to create its own system; optimal loads ensured via a shared approach
- Cost-savings – elimination of on-site plants reduces construction costs with no capital investment required for interconnections
- Ease of operation and maintenance – 24/7 staffing and all ongoing system maintenance provided by NRG's team of experts
- Architectural design flexibility – without the need to set aside space for expensive boiler and chiller equipment, building owners are able to increase leasable area, increasing rental income and overall building value. As an added benefit, rooftops are kept free from unsightly mechanical equipment that can negatively impact the life expectancy of roofs and detracts from the aesthetics of quality buildings
- Environmental protection – rigid emission standards maintained by NRG protect air quality and shield customers from stringent federal and local air pollution regulations connected to on-site boiler and chiller plants
NRG Energy Center Minneapolis began operations in 1972. It currently serves more than 100 customers, some who rely on it for heating, others for cooling, and many for both. Flexibility also takes hold as new buildings and customers come onboard into a system with available capacity and a design that accommodates growth.
