PILOT Presentation
This presentation applies only to the Electric Utility

Application of Cash Criteria
1. Keep the rates stable
2. Increase the transfer to the City, however, it should not be at the expense of existing Capital Expenditure Programming
3. Reduce Industrial Rates—number 1 above should take care of number 3, since no rate increase for a long time is the same as a rate decrease.

2011--Operating Expenses
Power Supply Expenses
Other Expenses
PILOT
•Approximately 70% of all electric utility expenditures are power supply expenses. •Other expenses will increase due primarily large increases in Transmission Expense. •Focus on reducing power supply expenses.

Power Supply Planning
The following items are included in this study, some have already been implemented, while others will likely be implemented in the future.
1. Rate stabilization fund is used—this was implemented in 2006. 2. Statistical Model being used by system control to dispatch generating units—implemented in
2012. 3. Base load supply was reduced from 30 MW to 25 MW—this was implemented on January 1,
2013. This supply comes from Missouri River Energy Services. 4. Unit 8 has a scheduled run in January, June, July and August—this has been implemented, and
functions as a hedge against the market. 5. Installation of new Wartsila 9.5 MW generating unit—Unit will go on-line in February 2013. Unit
will be used as a hedge against the real-time market. 6. Change air permit for units 3 and 4. Each of these units are 4 MW dual fuel units. Late spring
2013 we will identify what needs to be done (if anything), to gain added operating hours for both units. Anticipate this will be complete in 2014. Units will be used as a hedge against the real-time market.
7. Purchase and install a 2nd Wartsila 9.5 MW generating unit—we would like to see this unit go on-line in 2015/2016 time frame. This unit will be used as a hedge against the real-time market.

Power Supply agreement with Missouri River Energy Services
• Missouri River Energy Services(MRES) is a Joint Action Agency. HUC has a membership agreement with MRES. HUC’s electrical bill from MRES is based on a rate. All members of MRES have the same rate structure.
• MRES rate structure is seasonal, following is a breakdown of that rate structure: – Dec-Feb.—$53.1/MWHR – March-May--$44.1/MWHR – June-Aug.—$58.3/MWHR – Sep.-Nov--$44.2/MWHR
• Approximately 70 % of Hutchinson’s electrical energy supply comes from MRES. The other 30 % comes from market purchases or is generated using HUC’s power plants.
• Much emphasis has been placed on mitigating market risk as it relates to the 30 % that HUC provides Hutchinson. Market years 2006, 2007, 2008, 2009, 2010, 2011 and 2012 have all been treated as test years to determine the proper amount of generation that need to be installed at plant 1 to mitigate market risk.
• The following slides are a representation of the level of effectiveness of HUC’s strategies for the additional 30 % using a combination of market purchases and HUC’s electrical generation.

Plant 1 now has enough Generation to take care of HUC load. HUC will realize a small op. income from electric supply sold into market. The Op. Income received is subtracted from Wholesale rates charged to HUC retail customers.

•During times when HUC needs bundling most are the years HUC is transferring the largest amount to City in the form of PILOT. This reduces the effectiveness of bundling. •In the above examples, the statistical model for systems control was used. It should be noted the statistical model does not work as effectively on combustion turbines. The model was designed to work for reciprocating engines like those found at plant 1.

•Transfer is unstable—a range of approximately $100,000 to $450,000
•The years where HUC needs to apply Op. Income the most to stabilize rates corresponds with the years where HUC is transferring the most. In particular, high market year in 2007, and low market year in 2009.

Capacity Sales 2013 2014 2015 2016 2017 2018
Potential Capacity Sales(Op. Revenue) $112,000 $332,000 $572,000 $812,000 $1,052,000 $480,000
Less Transfer to City $5,600 $16,600 $28,600 $40,600 $52,600 $24,000
HUC additional cash flow $106,400 $315,400 $543,400 $771,400 $999,400 $456,000
•City will receive 5% of Operating Revenue, and HUC will realize a significant increase in cash flow. This added cash flow is not applied to further stabilize rates.
•A capacity contract is a wholesale sale with another electric utility, and could be viewed as an option on a plant to produce electrical energy for another electric utility.

Base Load--Point to Point Energy Sales(Steam Turbine at Plant 2)
Cost of Electric Production from Unit 1 (Combined Cycle) Plant 2 = Heat Rate x Price of N. Gas + Fixed Cost + Pilot % = 8.84 x 5 + 6.67 + 5%
Heat Rate(Combined Cycle) 8.84
Price of N. Gas--$/MCF 5
Plus Fixed Cost in $/MWHR $6.67
Expense per MWHR $50.87
Add-in 5% transfer $2.54
Total Expense per MWHR $53.41
MRES Agreement as a reference--annualized $/MWHR $49.94
Combined Cycle(MW) 52
Number of Hours per year 8760
Total MWHR's generated annually 455520
•HUC does not have a 5% margin on this type of a transaction. Every one dollar represents $455,520 of annual income. With a 5% transfer, the transfer would be approximately $1,150,000. •With a 5% transfer, it is unlikely that HUC would be able to do this type of a transaction. Consequently, the steam turbine at Plant 2 may become useless to HUC.
31
Roadway Lighting
• Presently HUC provides roadway lighting for
Free to the City. HUC charges the City for roadway lighting, and follows it up with an additional transfer. This is considered Operating Revenue, consequently HUC would pay 5% of something that it is providing for free.
32
Recommendations for Electric Utility
• Change the transfer percentage to 5% of retail operating revenue(metered sales on electric distribution system), do not include wholesale sales (sales for resale). Additionally, do not include roadway lighting.
• The 5% of retail operating revenue will include the electric utility expenses as it relates to Legal, HR, IT, and Roadway Lighting.
• HUC should break out its cost of goods sold(not counting transmission expense?), or power supply expenses into a separate business unit. This would include Sales for Resale—Capacity Sales and also Hedged, and Bundled Electrical Energy Sales.
• A dividend payment based off of Net Income would be made to the City from the new business unit.
• Look into creating an added line item in the budget for all of the other shared services found on the shared service list, and place this under “Other contributions” in the budget. No money would be exchanged, instead this line item would reflect labor, materials, equipment useage, etc. for other items contributed to the City’s operations. At this point, I am not sure how difficult it would be to do this, however, this is certainly something we could explore.
