Constellation pursues large back-up generation project in Texas

Constellation EG LLC (GenCo), an affiliate of Constellation NewEnergy (CNE), filed on April 29 at the Public Utility Commission of Texas for registration as a self-generator related to plans to build backup generation for a new data center in Plano, Texas.

Constellation EG is building a behind-the-meter backup generation system to provide emergency power to the end customer co-located at this site, and to be operated by GenCo for participation in load management programs. GenCo will sell the output of the generator to CNE for resale to the end customer. The end customer, Aligned Energy, parent of Aligned Data Center LLC, plans to open a data center in Piano in October 2015.

The initial on-site backup generation required is 12.5 MW. The load at the data center will grow over time, meaning the generation requirement will grow over time. Data center capacity is expected at 30 MW, meaning 60 MW of back-up generation will be required for redundancy purposes.

GenCo is subcontracting with PowerSecure Inc. to design, install, and permit the backup generation system, with a subcontract with PowerSecure to provide on-going O&M, monitoring and remote dispatch services. GenCo will operate the generator and enroll in the Electric Reliability Council of Texas (ERCOT) and market programs as allowable.
