OUR SYSTEMS OUR PEOPLE OUR SUPPLY MIX OUR SYSTEMS Wolverine owns and operates an extensive electric transmission network throughout Michigan’s Lower Peninsula. 1,600 MILES OF TRANSMISSION LINES Wolverine has approximately 1,600 miles of 69 kV and 138 kV looped transmission lines and associated facilities. Wolverine and other companies use these transmission facilities to integrate power supply resources with customer loads. 46 TRANSMISSION STATIONS & 146 DISTRIBUTION SUBSTATIONS Wolverine’s transmission system also includes 46 transmission stations and 146 distribution substations throughout the state of Michigan. MISO INTEGRATION In January 2006, Wolverine transferred operational control of its transmission facilities to Midcontinent Independent System Operator (MISO). MISO coordinates, controls, and monitors the electric transmission system throughout parts of the Midwest and Southern U.S., and Manitoba, Canada. Wolverine is regulated by the North American Electric Reliability Corporation (NERC), a not-for-profit international regulatory authority whose mission is to assure the reliability of the bulk electric power system in North America. NERC develops and enforces reliability standards; annually assesses seasonal and long‐term reliability strength; monitors the bulk electric power system through system awareness; and educates, trains, and certifies industry personnel. NERC’s area of responsibility spans the continental United States, Canada, and the northern portion of Baja California, Mexico. NERC is the Electric Reliability Organization (ERO) for North America, subject to oversight by the Federal Energy Regulatory Commission (FERC) and governmental authorities in Canada. NERC’s jurisdiction includes users, owners, and operators of the bulk electric power system, which serves more than 334 million people. OUR PEOPLE Wolverine employs the best and brightest people to perform all the necessary duties to ensure reliability. IDENTIFY Wolverine’s Supervisory Control and Data Acquisition (SCADA) system is the all-seeing-eye of Wolverine. Utilizing SCADA, operators are able to remotely monitor and control all systems and facilities to ensure reliability, security, and efficiency. Our expert SCADA programmers have automated SCADA to collect data on power flow, voltage, and equipment status. This data is continuously sent to our Energy Control Center (ECC) where our transmission system operators can quickly identify issues and make informed decisions. DIAGNOSE Wolverine’s ECC is at the heart of our operation. The ECC is equipped with sophisticated technology and highly trained specialists 24/7/365 to ensure power is reaching our members’ distribution systems. Our transmission system operators make certain the system is operating within thermal and voltage limits, that system-overloads do not occur, and that proper voltage is supplied to our members. They continually monitor our SCADA system, quickly diagnose an issue, and dispatch line crews for prompt action. RESPOND Wolverine’s field crew, made up of highly skilled line workers, technicians, operators, mechanics, and engineers, stands ready to act at a moment’s notice. These experienced professionals have been trained to immediately respond to any scenario at any time. Whether it’s in the middle of the night or the dead of winter, our field crew does not hesitate to safely and reliably keep the power flowing. By maintaining and testing every system, and rapidly restoring critical infrastructure, our field crew plays a vital role in keeping power reliable. 1,600 MILES OF TRANSMISSION LINES Wolverine’s support staff is the best in the industry. From human resources, accounting and finance, regulation and policy, land management, environmental, and legal to operations, communications, engineering, purchasing, safety, administrative, and information technology, our employees are highly trained and vastly skilled. The old saying, “it takes a village”, applies at Wolverine, because it takes each and every employee in every single department working together to ensure we deliver affordable, reliable power to our members.
