Biographical Information Robert Misbrener, Project Manager II, Office of the University Architect Kent State University, 615 Loop Rd, Kent, OH 44242 Phone: 330-672-9653 rmisbren@kent.edu

Robert Misbrener is a Project Manager on the Mechanical Engineering Team at Kent State University and has been in the capacity since 1999. He is the lead project manager for the majority of energy conservation projects that began in earnest in 2009 for Kent Campus and all Regional campuses in Ohio. Prior to Kent State, Robert worked at Scheeser Buckley Mayfield Consulting Engineers in mechanical design engineering for northeast Ohio for nearly 19 years. Robert has enjoyed nearly 39 years of experience in the mechanical engineering field for numerous infrastructures, new building, renovation, renewable energy and energy conservation

• projects. Many projects under his management were in the multi-million to over $20 million-dollar
• range. Robert is tasked with helping the University maximize the use of new/existing

equipment/capacity to serve the dynamic renovation and new buildings integrated on the

• campuses. Annual Electricity usage at Kent campus is the same as usage in 2012 despite

improving (adding A/C etc.) nearly 1 million GSF and new builds of nearly 350,000 GSF since

• 2012. The reliability of the Kent State academic mission has drastically increased due to the new

equipment and efficiency improvements of the energy conservation projects. The Deferred Maintenance component of Kent State has also benefitted from the energy projects, retiring over $38 million since 2009.

Agenda

• KSU Overview
• CHP History
• CHP currently at KSU
• Control Systems Used
• Resilience experience at KSU

Combustion Turbines Old Plant

• Heating plant was a 1940s design, coal and natural gas

boilers, efficiency/operations issues, no central chilled water facility, old electrical distribution system, land locked, required major upgrades to meet EPA guidelines.

• Starting considering CHP concept in the mid 1990s;

pivotal point was in 1997; issues with how to build a new plant/system while maintaining current operations and construction of the new facility

• New equipment/system would provide benefits, but

realized the advantages of CHP to lower electrical costs, improve efficiencies, etc. Further advantage was having ability to secure high pressure gas eliminating need for gas compressors for combustion turbines.

• Construction started in 2000; first unit GT1 installed in

2003, second unit installed in 2004; steam driven vapor compression chiller installed 2005.

Changes

• Natural gas price volatility; Hurricanes Katrina and Rita 2005; 2008 Credit

Crunch and Economic Meltdown; 2011 Shale gas takes off; cold weather periods.

• KSU starts multiyear risk management/hedge strategy to obtain natural gas

requirements in 2008.

• Electricity customer choice is available; FE part of PJM; other changes in

industry

• KSU’s new paradigm started in 2009.
• First 10 years regulated
• Risk adverse
• 2009 – 2013: transitioned moved to deregulated
• 2013 – 2015: optimized participation in the new markets

CHP Currently at KSU

• Spark spread difference between

buying vs. producing.

• Available when generating due to

tariff, gas prices, and generally low heat rates.

• Positive impact on PJM capacity

costs by using turbines, chiller fleet, energy management system, etc. appropriately.

• Positive impact on ATSI transmission

costs with the Now Market Based (NMB) Pilot Transmission Program by using turbines, chiller fleet, energy management system, etc. appropriately.

CHP Currently at KSU (Continued)

• Participate in the Emergency

Capacity Demand Response Program.

• Participate in the Economic Load

Demand Response Program.

• Will be entering Synchronous

Demand Response Program soon.

• Numerous energy conservation

projects throughout the campus.

• Can Island Mode.

CHP Currently at KSU (Continued)

• Can Black Start but not fully developed at this time.
• Cannot export into grid due to technical/equipment issues – will be

working on this.

• More items being explored.

Control Systems Used at KSU

• Multiple resources available for

support.

• Hierarchical and decentralized system

with all units capable of operating with local controls if necessary. Ethernet ring for communications. Can operate equipment from control room or remotely on operating floor with proper equipment/connection.

• Isolated private network with secure

access controls data flow into and out

• f plant.
• Rockwell PLCs in Power Plant using Wonderware for

boilers, turbines and BOP equipment.

Control Systems Used (Continued)

• JCI Metasys used on chillers
• Hierarchical and

decentralized system with all units capable of

• perating with local controls

if necessary. Ethernet network for

• communications. Can
• perate equipment from

Energy Management Office

• r remotely with proper

equipment/connection.

• Isolated private network.

Control Systems Used (Continued)

• Proper and good quality communications required between Power

Plant, Energy Management, and UFM.

• Recently installed math based Model Predictive Control system to
• ptimize plant operations. JCI EOS
• Minor adjustment to equipment/operations are done with local

controls or EOS commands.

• Major adjustments are a combination of EOS commands, EMG

commands, or decisions by Power Plant personnel.

Resilience Experience at KSU

• The ability to routinely test and train personnel in

Island Mode and Black Start operations has been

• challenging. This is required and needs to be done

with routine frequency. A single test or multiple tests with extraordinary assistance is not a realistic test.

• Consider the impact of inrush current and

equipment capabilities. Consider alternative system designs to avoid problems and allow for maintenance activities. Consider a mix of generation resources to alleviate issues. Research any EPA ramifications.

• Determine what level of service is actually required

and size equipment, with ample contingencies, and install it. Be realistic and anticipate problems. Adequately communicate the expected level of service including anticipated curtailments.

Resilience Experience at KSU (Continued)

• People have experience on the

consumption side but there is limited experience on the production side. There can be misunderstandings on how the two merge with less than desirable results. Make sure your people are adequately trained.

• As mentioned earlier, KSU can

Black Start but this will require additional effort to resolve the

• issues. However, we have had

multiple positive experiences recently with Island Mode.

Resilience Experience at KSU (Continued)

• KSU’s Island Mode Experiences:
• We have been able to test Island Mode on a yearly basis, typically on the

celebrated Veterans Day for the campus, or as required for other time

• periods. This process has been “formalized” and helps to reduce the anxiety
• f this event. Further, we perform the required maintenance on the controls

and instrumentation as required.

• For some time periods, campus load reductions will not be required, but

during other time periods load reductions are necessary.

• Emergency generators are tested routinely and changes are made as

required.

• We identified each load/feeder breaker with a priority number. This is

reviewed annually to accommodate any changes on campus.

Resilience Experience at KSU (Continued)

• KSU’s Island Mode Experiences:
• Load control is accomplished by several methods to prevent the turbines from

tripping.

• Minor load changes can be done by JCI Metasys by the Energy Management Group.

These are a combination of shutting off unneeded equipment, lights, etc.

• An “all stop” switch is available in the Power Plant Control Room to shutdown a wide

array of equipment quickly, if required.

• A load control program is operated by EMG that shuts down additional equipment if
• required. The parameters of this program can be changed to meet the conditions.
• A Load Shed program with variable/selectable inputs automatically curtails load by
• pening load/feeder breakers to the campus. This is done by tripping the lowest priority

load first and will continue every 3 seconds until the load is within parameters.
