Energy Management System
Accomplishments
A Clean Water Agency
 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.

Plans
 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.

Employee Energy Campaign
A Clean Water Agency
October 2008 – October 2009
 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

B. MCES Renewable Generation
A Clean Water Agency
 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

Metropolitan Energy Policy Coalition
(MEPC) Wind Initiative
Council joined MEPC on December 2006
 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

MEPC Wind Initiative (Continued)
A Clean Water Agency
 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)

MEPC Wind Initiative (Continued)
A Clean Water Agency
 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?
