1. Union Church Path to Net Zero Energy (10 Years of Progress)

2. MACED Mission… To work with people in Kentucky and
Central Appalachia to create economic
opportunity, strengthen democracy and
support the sustainable use of natural
resources.

3. Our E3 Service Area
The 54 Kentucky Counties Designated by the Appalachian Regional Commission

4. The Purpose:
Strengthen the region’s enterprises by helping reduce energy costs and consumption

5. The Team Jason Coomes Energy Programs Manager Joshua Bills
Commercial Energy Specialist

6. The Benefits:
An enterprise that pays lower utility bills has more money to invest in people, further clean energy and community
Demand for new skills in plumbing, HVAC, lighting improvements can lead to job creation and security
Pollution reduction

7. Union Church – Baseline
In the beginning…
OCTOBER 2007 TO SEPTEMBER 2008
Natural Gas Use ,000 ft3
Electric Use ,640 kWh
HOW TO COMPARE?
Convert both to MMBtu (about the energy from a million matches)
1 ft3 Natural Gas = Approx Btu or MMBtu
1 kWh = 3412 Btu or MMBtu
Natural Gas MMBtu $12,115
Electric MMBtu $6,991
Above Costs Do Not Reflect Base Fees Nor Demand Charges (in the case of electric)
OCTOBER 2007 TO SEPTEMBER 2008
Natural Gas Costs = $ per MMBtu Today (2017) NG = $9 per MMBtu
Electric Costs = $ per MMBtu Today (2017) Electric = $18 per MMBtu

8. Energy & Cost Saving Measures
Billing evaluation--IMPORTANT
Identify no cost savings opportunities
Turn off Natural Gas During Unused Months
Upgrade Building Envelope
Lighting Upgrade
Monitor and Manage Electricity Demand
Boiler Replacement/Heat-Cool Distribution
Upgrade/Thermostat Upgrade
Solar Thermal for Space/Water Heating
Solar Electric
Billing Evaluation—sales tax, optional rate classes—true evaluation of savings impacts—where to look
EC has done everything EXCEPT solar thermal

9. Efficiency Takes Hold
2012 excluded only includes months of January and February
51.6 percent less energy 2016 from 2007 in spite of 14 percent more degree days
Total annual energy expenditure dropped $6,300—takes a LOT OF SOLAR to make $6,300 of electricity

10. Apples to Apples 2012 excluded
51 percent less energy 2016 from 2007 in spite of 14 percent more degree days

11. Solar on Top of Energy Savings
Estimated to offset 25 percent of overall use
78 percent self consumed
Self Consumed Electricity $555 (2016)
Exported Electricity $84 (2016)
Savings on Demand $230 (2016)
Different value streams (July to December 2016):
Self Consumed Electricity $555 ($0.0601/kWh)
Exported Electricity $84 ($0.0324/kWh)
Savings on Demand $230 ($6.095/kW)

12. Demand vs. Usage
BMU’s electric charges are based on both monthly consumption (Total kWh) and peak power draw – averaged over 15 min. (kW)
$6.095 per kW
Coffee Pot—1.5 kW over 15 minutes and happened at monthly peak. kWh costs would be 1.5 kW (x15/60) = kWh x = $0.0225
kW 1.5 x = $9.14
$ per kWh

13. 35 Percent of annual costs are Demand (kW) Charges!

35 Percent of annual costs are Demand (kW) Charges!

14. What Does It Look Like? August 2016 w/o solar
Sunday Morn and Wednesday Eve

15. What Does It Look Like? August 2016 w/ solar
Difference of max is zero—the peak demand happened at 8:45 PM
Still morning and evening peaks

16. Does solar help demand? SOMETIMES
Load demand curve. Blue is net 50 highest demand periods (i.e. at BMU meter) for the month of September. Orange is actual building demand at those times (w/o accounting for solar). Top
three 15-minute demand periods were reduced by solar. Savings for this month was $92 in demand charges for Sep. Energy savings this month was $115 with solar.
