1. Call Meeting to Order
Chair Zehringer called the meeting to order at 8:32 a.m. and welcomed representatives from
Faribault Foods and Salk Middle School to the meeting. Introductions of the commissioners
• followed.
2. Consider December 21, 2011 ECC Agenda
MOTION BY COMMISSIONER SETTERHOLM AND SECOND BY COMMISSIONER
STEINBECK TO APPROVE THE AGENDA AS SUBMITTED. ALL IN FAVOR. MOTION
CARRIED.
3. Consider November 16, 2011 Minutes
MOTION BY COMMSSIONER AND SECOND BY COMMISSIONER TO APPROVE THE
November 16, 2011 MINUTES WITH NO CHANGES. ALL IN FAVOR. MOTION CARRIED.
4. Faribault Foods High Five Award Presentation
John Anderson and Dave Zimmerman of Faribault Foods were present to receive the Triple High
Five award their company earned in 2011 for earning more than 30 points on the High Five
program. Prior to presenting the Triple High Five award to the gentlemen, Chair Zehringer
discussed the projects that Faribault Foods has implemented through grants, rebates, or
suggestions from Elk River Municipal Utilities. Faribault Foods has received rebates totaling
$35,000 for the upgrades and changes they have made. All together, the changes have had a net
savings of 500,000 kilowatt hours and will save Faribault Foods approximately $50,000 per year.
• An additional change that Faribault Foods plans to implement at their company for additional
energy savings is installing fluid coolers on the roof to use cold winter air rather than electricity for
cooling in the plant.

5. Salk Middle School Presentation
Ms. Kelly Prusak (curriculum coordinator for Salk Middle School) was present with Ms. Jennif
Athman (Principal, Salk Middle School) to discuss the STEM (science, technology, engineerin ,
mathematics) program at the 6 — 8th grade Magnate School. Ms. Prusak did a power point
presentation highlighting each of the aspects. She invited the Energy City Commissioners to be
involved in Salk's "Engineering Week" scheduled for February 21 — 24th. This is the school's fifth
year as a STEM magnate and started as a result of a grant for desegregating the Osseo school
district. Students come from communities as far south and west as Rockford and Buffalo. The bus
rides can be up to an hour long, but Ms. Athman jokes that "the ride is worth it".
There will be a Science Fair from January 10 — 12th that people can volunteer to be judges for as
well. The judging times are two hour blocks and all interested people are invited to participate.
Commissioner Steinbeck expressed interest on the part of Great River Energy. Ms. Deckert
commented that she could put Salk administrators in contact with other manufacturers. Ms.
Prusak thanked everyone and stated "Anything hands on, the kids LOVE".
6. Business and Energy Expo Discussion
The decision has been made to tentatively merge the Energy Expo with the Business Expo for a
one year trial period to "see how it goes". It will now be called the Business and Energy Expo. The
expo will be held on March 25th from 10 a.m. — 2 p.m. instead of Saturday, March 10t . There will
be an "Energy Alley" in the gymnasium. The Chamber of Commerce is looking to the commission
for assistance with advertising and assistance with permits (for example, signs on City property).
There will be different back drop curtains for the Energy Alley and possibly an archway with LED
lights. Because the Energy Alley area will be limited in size (two aisles with a central opening to
facilitate movement between the aisles), there will be an application process to be able to get into
the Alley. Each booth must be manned.
ECFE (Early Childhood Family Education) will continue to have children's activities in the
Community Room. The Community Education Adventure Club will participate once again but it
hasn't been determined where their exhibits will be located yet.
Chair Zehringer questioned fees, especially regarding non-profits ($155 Chamber cost vs. $25
Energy Expo cost). Discussion followed that there were only 5 — 6 non-profits last year. Another
meeting will be held following the New Year to figure out details. Chair Zehringer expressed
concern over losing our identity.
7. Project Conserve Phase Ill Update
Chair Zehringer reported there are approximately 50 audits scheduled, most of which are Level 2
(with blower door and infrared tests). They have been finding typical maintenance issues such as
not having windows latched. Many homes have less insulation than preferred in the attic. 14
inches (R-38) but auditors are seeing a few with 6 — 8 inches. Some settling may have occurred,
but additional insulation is a recommendation as a result. The audits have been scheduled out into
February.
An intern will be starting on January 9th. Her name is Rachel King and she will be working
primarily on the organics program but will also help with the energy portion of Project Conserve. •
She will be working through the end of April.

Ms. Deckert questioned whether any of the downtown businesses are involved in Project
• Conserve. Chair Zehringer commented that there are a couple of businesses interested but there
is no certification program for commercial audits so the auditors are not "official" commercial
auditors. Discussion followed regarding differences between residential and commercial audits.
Different equipment is necessary for commercial audits. Commissioner Setterholm shared that
commercial audits through Centerpoint Energy are done by engineers. Downtown businesses
may receive an energy "walk through" versus "audit".
8. Photovoltaic Discussion — Scott Hagen
Commissioner Hagen discussed a concept with micro-inverters that monitor energy consumption
and production regarding solar (photovoltaic) systems. He stated that there is direct current (DC)
at the panel and alternating current (AC) output at the inverter. The output is then sent directly to
the electrical grid.
The set up Commissioner Hagen discussed involves one micro-inverter per 60 cell panel which
essentially makes each panel its own array so that they can operate at optimum efficiency.
He explained that with a central or string inverter, the array is only as efficient as its weakest panel
so if one panel is functioning at less than 100% (for example if a leaf falls on the panel), they all
function to that new, lower level (rather than only the panel with the issue being at lower
efficiency).
Currently there is only one known Enphase micro-inverter grid-tied system to Elk River Municipal
Utilities in Elk River (north of town). Discussion followed regarding companies that are working on
• AC arrays, load factors, and future costs of electricity due to old coal plants being closed.
Panel costs as well as inverter costs are coming down. Commissioner Hagen commented that
passive systems do help conserve energy. On the wholesale side, cost is below two dollars per
watt. It was commented that the cheapest rates seen for installed (central inverter) systems is
$7/watt.
Further discussion followed regarding system sizes. China is planning a 2-gigawatt solar
photovoltaic system. The largest in the United States is in Arcadia, Florida (25 Megawatts).
Commissioner Hagen answered questions regarding the micro-inverter approach. He stated that
each one syncs to the grid system and they are powered by the generated DC voltage, but require
AC voltage present to function (booting up at 24 volts DC, then warming up and starting) so if the
electricity goes out, the inverters de-energize and go dormant. The micro-inverters are purely grid-
tie and do not lend themselves to a battery storage system like the DC central inverter projects.
Micro-inverters cost between $130 - 150 each and are warranted to 20 — 25 years. A comment
was made that rebates artificially keep the costs high but do help keep the industry going.
Elk River Dave Raymond installed a 4 KW system for $45,000 (with rebates). A comment was
made that on a 4 KW system, a person would not want to have an electric stove, water heater, or
dryer.

No other topics were discussed.
