Supporting NCCU’s Educational Mission – with “Real-Time” Energy Measurement & Reporting

2 Summary of Today’s Topics

3 NCCU Site Assessment for Energy and Utilities April 2007 From the Site Assessment: Opportunity: Energy Data Collection Via Campus Metering Systems “Ultimately, NCCU’s goal is to be able to better track where all forms of energy are being consumed, resulting in better energy utilization, and verifiable energy conservation.”

4 Why Duke Energy’s Approach? Duke Energy’s Approach will Allow NCCU to: ………. Enhance the Educational Mission of NCCU 1.Create “Energy Awareness” for all students, faculty and staff 2.Allow students and faculty on-line access to relevant energy use 3.Foster better understanding and cooperation between students, faculty and staff about saving energy in their personal environments 4.Provide students with additional study opportunities in fields of Science and Energy Improve Campus Energy Efficiency and Sustainability Achieve fast, accurate and automated recording of campus energy consumption Receive user-friendly energy displays and reports Improve energy cost accountability for all campus departments and facilities Meet State requirements for energy measurement Demonstrate justification for future energy improvement measures

5 NCCU Energy and Utility Measurement & Reporting Needs Established the need for greatly improved energy measurement and reporting 1.Measure and track energy & utilities at the individual facility level 2.Track where all forms of energy/utilities are being consumed 3.Accounting allocations 4.Measure & track energy for all receipt-funded departments 5.Improve energy utilization and conservation 6.Identify cost-effective EE opportunities & projects 7.“M&V”: Measure & Verify effectiveness of EE projects

6 NCCU Energy and Utility Measurement & Reporting Needs Current Energy Measurement Approach: 1.Manual data collection and entry 2.Various data storage files and displays 3.Energy data integrated into other campus reports 4.Energy use on campus is not readily visible a.To administration, staff & faculty b.To those who use it (students) Disadvantages of this Approach: 1.Labor-intensive (expensive) 2.Slow 3.Cumbersome 4.Introduces error 5.Difficulty integrating into other reports 6.Less than ideal displays 7.Only PP personnel have energy awareness

7 NCCU Energy and Utility Measurement & Reporting Needs Desired Approach for Energy Measurement & Reporting 1.Create campus-wide Energy Awareness 2.Automate all energy & utility measurement (meters) in real time 3.Automate all data collection (interrogation) 4.Automate all data entry and report generation (storage, displays) 5.Benchmark energy & utility consumption characteristics a.On a facility level b.On a department level c.On an energy & utility type 6.Identify high energy & utility consumption in real time 7.Identify Energy Efficiency opportunities 8.Verify effectiveness of projects 9.Use energy & utility data to make financial decisions 10.Use energy & utility data to make operational decisions in real time

8 Why Duke Energy’s Real-time Energy Metering Service? It is a Unique Solution The service and cost are competitive in the marketplace The service and cost are superior to self-performing Utilizes a meter offering approved by the NC Utility Commission Provides NCCU with an opportunity to participate in state-of- the-art technology installation with little or no risk Requires little or no appropriated capital by NCCU to install equipment and provide the services Provides access to Duke Energy’s knowledge of metering and on-line reporting Delivers information in a manner everyone can understand

9 Possible Energy Measurement Solutions – Phase I Start-up Energy Measurement System For NCCU Proposed Basic Capabilities 1.Electric Power Meters a.Duke-owned b.NCCU-owned 2.Automated data collection in real time 3.Automated data storage and reporting in real time 4.User-friendly data and report displays 5.Very secure on-line web page access and display in real time 6.Expandable - all other metered campus energy and utility uses

10 Possible Energy Measurement Solutions – Phase I A new means for metering and data collection from remote locations: 1.Over 1 year in development 2.Real-time capabilities within 5 minutes (maximum) 3.State of the art, mesh network technology reduces expense 4.Very cost-effective 5.User friendly interface and information display

11 Possible Energy Measurement Solutions – Phase I OK, is it economically justified? Energy Awareness: initial 3% to 5% per year reduction in energy consumption is a reasonable target, given current low levels of awareness (exclusive of individual energy management projects) NCCU’s power costs are in excess of $2.1 MILLION per year EPA Experience: Energy cost reductions have accrued to over 10% per year. Target individual projects: ?%

Possible Next Steps: NCCU approves concept & price range estimates Duke Performs Scoping for Engineering and Design Duke Determines Firm Pricing for both Agreements NCCU & Duke Execute RMRDS Service Agreement & MSA Duke Installs and Commissions NCCU begins operation!
