Green House Data Relies on Generac Power for Redundancy, Scalability


Green House Data offers cloud, colocation, and managed IT services from highly efficient data centers across the United States. The company’s high-touch customer service model and transparent, community- and sustainability-oriented business model have helped fuel expansion to seven locations and over 75 employees in a matter of years. After outgrowing the original flagship data center in Cheyenne, Wyoming, Green House Data began the process of building a new world-class facility that could accommodate such rapid expansion.

Leadership chose the plot directly next to the original building in order to create a data center campus in Cheyenne, which is an attractive site for the industry due to its natural assets: virtually no risk of natural disasters and the opportunity to use ambient air 365 days per year for data center cooling. The location also provides access to a large fiber optic network which links to multiple Tier 1 national backbones.

The new Cheyenne 2 building is 35,000 square feet with 16,000 devoted to data center white space. Because the company focuses on reliability, redundancy, and scalability, they were open to innovative strategies geared towards efficient equipment, facility design, and operations that could strengthen the company’s commitment to green technology.

Rocky Mountain Power Generation (RMPG), a member of the Generac Industrial Power network based in Denver, CO, worked with Green House Data to create a large kilowatt (kW) paralleling generator system that offered the flexibility, scalability, and reliability required for an industrial-scale data center. The two companies had previously worked together to help Green House Data meet customer demand in their original headquarters.

“We began working with Green House Data when the company was still new, in the fall of 2008,” said David Coxon, president, RMPG, which is located in Denver, CO. “We provided startup assistance and maintenance for a previously-owned Generac SD500 generator at the first Cheyenne data center.”

In 2011, RMPG replaced and upgraded the unit with a Generac Modular Paralleling System (MPS) MD500. In 2012, two more MD500 expansion units were added for a total system capacity of 1.5 MW.

“Based on our customer service and Generac’s equipment providing reliable power at a good value, the relationship has grown and prospered,” Coxon said.

For the new Cheyenne facility, RMPG provided two Generac Gemini diesel generators with utra-high levels of reliability. Each Gemini has two 500 kW MPS units for a total of two megawatts (MW), powered by 2,310-gallon fuel tanks that can provide up to 36 hours of run time at full system load.

The MPS system, which is fully compliant with NEC 700 and NFPA 11, also includes a PowerManager® Digital Controller which uses mission-specific software that enables it to function as the controller for the individual gensets, replacing multiple generator controllers and expensive paralleling switchgear.

“We designed the system to scale up to 6MW to meet the needs of anticipated customer growth. This allows Green House Data to effectively manage resources—they can quickly scale up to meet demand, without overspending on the initial investment,” Coxon said. “The customer even pre-poured the concrete pads for the future generators to reduce costs and speed up the installation process.”

In addition, Green House Data had a third-party present during the commissioning to verify that the generators were operating per spec.

Generac offers a variety of standby power options that can help companies meet energy efficiency goals, while also providing optimum power needed, including natural gas solutions.
