1 Metropolitan Council Environmental Services October 14, 2008 Presented to Environment Committee Metropolitan Council Energy Update By Jason Willett

2 Why Energy Focus? Substantial Cost of Operations Rising Rates Preparing for Climate Change Costs & Regulations State Initiative — Energy Independence & Security — Midwest Governor’s Cap & Trade — Renewable Energy Standard

3 2007 Energy Costs Metro Transit and Environmental Services Divisions Metro Transit BUSLRT Electricity$1,670,355$1,702,560* Natural Gas1,839,68445,832 Fuel16,469,8600 $19,979,899$1,748,392 TOTAL COST: $21,728,291 MCES Electricity$13,509,612 Fuel Oil27,049 Natural Gas2,724,430 Motor Vehicle Fuel570,845 $16,841,937 TOTAL COST: $16,841,937 *$963,441 is for train propulsion.

5 MCES Energy Strategies A.Conservation B.Renewable Energy Generation C.Financial Strategies D.Climate Change Regulatory Preparation

6 A. Conservation Goal: 15% reduction of purchased (fossil fuel) energy Process Efficiency Program — 26 studies completed (10-1-08) — 24 studies scheduled (2009) — 11 actions taken — 16,000,000 kwh savings estimated — $1,000,000 savings per year estimated — $5,000,000 of energy improvements budgeted over next 5 years Energy Management System Employee Energy Campaign Work Instruction for Operations Staff Design Guidelines for Engineering

7 A. Conservation 2008 Energy Intern Work — Green House Gas-N2O Emissions — Centrate Treatment @ Metro — Dissolved Oxygen Set Point Optimization & Control Changes — Optimization of Blowers & Sequencing 2009 Energy Interns (possible) — Greenhouse Gas Modeling — Phosphorus Reduction — Aeration Efficiency Engineering — Emissions Reporting

11 Reviewed several vendors’ energy management software and service. Joined with Transit to send out a request for information. Developed real time electric energy use reports for Metro, Seneca, and Blue Lake. Tracking historical use for all wastewater treatment facilities on a monthly basis. Developed an energy metric that allows us to measure impact of our energy measures at Metro. A.Conservation Energy Management System Accomplishments

12 A.Conservation Energy Management System

13 Obtain electric interval meter data for all facilities Incorporate gas and other utility information into energy reports. New metering so real time gas and electric information can be displayed. Incorporate rate models for billing analysis. Develop energy metrics for other facilities and sub processes. Develop energy dash boards and reports. A.Conservation Energy Management System Plans

14 A.Conservation Employee Energy Campaign IS will be reconfiguring all 1800 desktop computers to drop into a very low energy state after 60 minutes of inactivity All printers will be defaulted to print two-sided copies Employees will be requested to: 1)Shut down computers when absent from their desks for long periods of time or at the end of the work day 2)Turn off task lighting when not needed or at the end of the work day 3)Turn off any additional electrical items (fans) when not needed or at the end of the work day October 2008 – October 2009

15 B. MCES Renewable Generation Steam Energy Optimization — Heat Recovery Study – Auxiliary Boiler – Alternative Biofilter Humidifier — Steam Trap Maintenance Program Microturbine Demo Program at Empire Thermal Recovery at Eagles Point Biogas Generation & Reuse at Blue Lake — 1,075,000 therms/year at approximate value of $800,000/year

16 B. MCES Renewable Generation (Contd) Algae-to-Fuel Research with University of Minnesota — $1m work plan, began on 7/1/08 — $0.5 funding secured from State MEPC/County Wind Initiative Xcel/Council Solar Farm Concept — 1-2 MW at Blue Lake Plant — Likely RFP in January

17 B. MCES Renewable Generation (Contd) Other Ideas — Energy crop at Empire — Fats, oils, grease extraction for energy — Screenings digestion for biogas — Small hydro at Rosemount or Eagles Point

18 Metropolitan Energy Policy Coalition (MEPC) Wind Initiative MEPC/RMEB Explore Wind Initiative — 2006/2007: Avant/Lindquist Business Concept — 2007: LCCMR grant $200k for technical fiscal analysis — 2008: Legislative Bill – Clarify local gov’t authorities under CBED – Counties may own, bond and tax for renewable energy – Counties may pre-pay for energy Council joined MEPC on December 2006

19 MEPC Wind Initiative (Continued) HGA Consultant Team Hired in 2008 Phase 1 analysis complete in August of 2008 — Concept: develop approximately 10 Megawatt wind farm — Sites in SW Minnesota identified (e.g. Lyon County Landfill) — Shows financial feasibility (with reasonable cost assumptions)

20 MEPC Wind Initiative (Continued) Phase 2 Analysis — Execute contract with Stoehl Rieves — Negotiate with utility for power and purchase access — Lyon County decision? Next: Determine “Coalition of the Willing” (Joint Powers Agreement) — Seek additional legislation (to finance project) — December AMC meeting – decision?

21 C. Financial Strategies Peak Control Agreements with Xcel Energy Hedging Contracts to Stabilize Natural Gas Costs Carbon Emissions Cost Added to Energy Cost for Future Engineering Options Analyses Analysis of Wind & Solar Economics Review of Tariff Options for Lift Stations

22 C. Financial Strategies (Continued) Energy Services Agreement with CenterPoint for N.G. Discount TBD: Accreditation to Minimize Possible Penalties for FBI/Cogeneration TBD: Review of “Monetization” Possibilities for Emissions Reductions TBD: Analysis of Break-Even Point on Peak Control Agreements Possible: Participation (with Chamber of Commerce) in Rate Case(s)

23 D. Climate Change Regulatory Prep The Climate Registry — Reporting all 2008 emissions — To be verified in 2009 — Protocol development MEPC Forum for Administrators: 11/20/08 Cap & Trade Status

24 Council Policy? To frame and focus Council’s energy actions 1)Conservation: investment directive 2)Biofuels directive (to support state agriculture) 3)Renewable energy directive 4)Energy financial management 5)Energy budget stabilization goal 6)Energy in community planning, assistance 7)Partnerships

26 Metro Council - Transit New Technologies — Diesel Particulate Filter 85% particulate matter reduction compared to 1995 buses — Tire Design Potential savings is 306,000 gallons per year — LED Interior Lighting — Lighter Passenger Seating — Lighter Flooring — Hybrid Bus 1,400 lbs lighter — Standard Drive Bus 3,000 lbs. lighter Hybrid Buses — 60 Hybrids in Service — 28% Better MPG — Lower Emissions — 172 Hybrids by 2012 — Saves 350,000 Gallons per Year by 2012 The benefits of the Go-Green Initiative---

27 Metro Council – Transit (Benefits Continued) Biodiesel — State Mandate B2 September 2005 — Metro Transit B5 in July 2006 — Metro Transit B10 in August 2007 — 755,469 Gallons of B100 — Currently Using B20 — Impact Annual reduction in non-renewable fossil fuel (1,266,000 gallons) — Metro Transit Fuel Plan B10 November 1 to February 28 B20 March 1 to October 31

28 Automatic Northwrite data upload to our database server from Xcel / Northwrite reports we receive every month for Metro and Seneca

29 Real time energy data access for Metro, Seneca and Blue Lake electric meters via web browser (our reporting website)

30 Developed Northwrite type electric charts using real time data for Metro, Seneca and Blue Lake accessible via our website (Example 2)

31 Developed Northwrite type electric charts using real time data for Metro, Seneca and Blue Lake accessible via our website (Example 3)

32 Developed Northwrite type electric charts using real time data for Metro, Seneca and Blue Lake accessible via our website (Example 4)

33 Developed Northwrite type electric charts using real time data for Metro, Seneca and Blue Lake accessible via our website (Example 5)

34 Compared the Xcel billing data with real time data for Metro, Seneca and Blue Lake to determine the accuracy of our electric meters

35 Compared Metro plant daily demand for last 2 years with the daily demand regression model to determine energy saved
