Background The University of Texas MD Anderson Cancer Center is one of the largest cancer centers in the United States, we span more than 15 million square feet across 40 structures and three campuses. We serve hundreds of patients at any given time. MD Anderson Cancer Center is supported by an emergency power supply system (EPSS) consisting of: 61 backup generators, with over 50 MW capacity a sophisticated fuel system that feeds 300,000 gallons of diesel to the generators, an electrical distribution system composed of over 200 automatic transfer switches, electrical switch gears, and parallel gears supported by breakers, synchronizers, and other sophisticated controls.
Codes & Standards NFPA 111 Standard on Stored Electrical Energy Emergency and Standby Power Systems NFPA 110 Standard for Emergency and StandbyPower Systems NFPA 101 Life Safety Code NFPA 99 Healthcare Facility Code NFPA 70E Standard for Electrical Safety in the Workplace The Joint Commission (TJC) Centers for Medicare & Medicaid Services (CMS)
Codes & Standards CMS 42 CFR 482.15(e) Effective 15 November 2016 482.15 (e)(1) Emergency generator location. The generator must be located in accordance with the location requirements found in the Health Care Facilities Code (NFPA 99 and Tentative Interim Amendments TIA 12-2, TIA 12-3, TIA 12-4, TIA 12-5, and TIA 12-6), Life Safety Code (NFPA 101 and Tentative Interim Amendments TIA 12-1, TIA 12-2, TIA 12-3, and TIA 12-4), and NFPA 110, when a new structure is built or when an existing structure or building is renovated. 482.15(e)(2) Emergency generator inspection and testing. The hospital must implement the emergency power system inspection, testing, and maintenance requirements found in the Health Care Facilities Code, NFPA 110, and Life Safety Code.
Codes & Standards Joint Commission EC.02.05.07, EP 4-10 Projected to become effective 9 January 2017 EP 4 - At least weekly, the hospital inspects the emergency power supply system (EPSS), including all associated components and batteries. The results and completion dates of weekly inspections are documented. Note: For additional guidance, see NFPA 110-2010: 8.3.1; 8.3.3; 8.3.4; 8.4.1. EP5 - At least monthly, the hospital tests each emergency generator under load for at least 30 continuous minutes. The cool-down period is not part of the 30 continuous minutes. The test results and completion dates are documented. EP 6 - The monthly tests for diesel-powered emergency generators are conducted with a dynamic load that is at least 30% of the nameplate rating of the generator or meets the manufacturer s recommended prime movers exhaust gas temperature. If the hospital does not meet either the 30% of nameplate rating or the recommended exhaust gas temperature during any test in EC.02.05.07, EP 5, then it must test the emergency generator once every 12 months using supplemental (dynamic or static) loads of 50% of nameplate rating for 30 minutes, followed by 75% of nameplate rating for 60 minutes, for a total of 1 ½ continuous hours. Note: Tests for non-diesel-powered generators need only be conducted with available load. EP 7 - At least monthly, the hospital tests all automatic transfer switches on the inventory. The test results and completion dates are documented. EP8 - At least annually, the hospital tests the fuel quality to ASTM standards. The test results and completion dates are documented. Note: For additional guidance, see NFPA 110-2010: 8.3.8. EP 9 - At least once every 36 months, hospitals with a generator providing emergency power for the services listed in EC.02.05.03, EPs 5 and 6, test each emergency generator for a minimum of 4 continuous hours. The test results and completion dates are documented. Note: For additional guidance, see NFPA 110-2010, Chapter 8. Note that NFPA 110 requires the transferring of all ATS during the triennial test. EP 10 - The 36-month diesel-powered emergency generator test uses a dynamic or static load that is at least 30% of the nameplate rating of the generator or meets the manufacturer s recommended prime movers' exhaust gas temperature. Note: Tests for non-diesel-powered generators need only be conducted with available load.

During a recent visit by The Joint Commission surveyors, UT MD Anderson Cancer Center review of the EPSS documentation took less than 30 min. This is the culmination of code compliance, third party verification and team work. Surveyors were presented with a binder that contained all equipment required maintenance & compliance followed by detail information of corrective and proactive work. It also included pertinent EPSS institutional polices and procedures And a summarized spreadsheet that included: Test Date Frequency Compliance Applicable Readings Test duration Test Result Documentation

What is Demand Response? It is a program that encourages customers to reduce demand, thereby reducing the peak demand for electricity among the utility power system. Demand response allows end-use electric customers to reduce their electrical usage in a given time period, in response to a utility power system reliability and financial incentive. MD Anderson has and is participating in DR programs for both Electrical Reliability Council of Texas (ERCOT) and CenterPoint Energy CPE. Last year several generators ran for 4 hours shedding 4MW of power from the grid and proving that our EPSS is operating as intended during peak demand time.
