To: Board %J Directors
From: Stephen Hollabaugh
Date: February 11, 2015
Subject: Discussion of 2014 Purchase Power Load, Resources, Peaks,
and Comparison to 2014 Budget Forecast
1. WHY THIS MATTER IS BEFORE THE BOARD
This workshop is to review the District's actual versus budgeted purchase power costs and
energy consumption for 2014.
2. HISTORY
On September 18, 2013 the workshop "FY14 and FY15 Budget: Purchase Power Plan" was
presented to the Board. This workshop covered the following topics:
Mission Statement and Objectives, Renewable Portfolio Standard Target, Conservation as First
Resource, Diversified Power Supply Plan, Future Renewable Resources, CARB Cap and Trade,
Proposed Resources for 2014 & 2015, Risk to Budget Analysis and 2014 & 2015 Forecast Costs,
The Purchase Power Plan 2014 and 2015 Budget was approved by the Board on November 20,
2013. The 2014 Purchase Power Plan budgeted amounts, based on a forecasted energy
purchase of 164,713 MWh, are shown in the following table:
Cost Component Budget $per MWh
Total Energy Supply -Various $1111913445 $67.95
Transmission Wheeling - SPPC $ 17204,628 $ 7.31
Scheduling - NCPA
Central Valley Project - WAPA
Totals
$ 75,423 $ 0.46
$-281012 $ -0.17
$125443,484 $75.55
Historical data for 2014 and prior years to 2005 is included for reference on Attachment A.
3. NEW INFORMATION
Summary budgeted versus actual amounts for 2014 are shown in the following table:
Description Budget Actual
Total Energy Purchases $12,443,484 $11;552,145
Total Energy Consumption, MWh 164,713 158,245
Purchase Cost per MWh $75.55 $73.00
• The total purchased power costs were 7.2% less than budgeted and total energy
consumption was about 3.9% less than forecasted during 2014. The two major factors that
affect the total purchased power cost are resource cost and energy consumption by our
customers.
All these factors helped to reduce the District's actual purchased energy cost to $73.00 per MWh,
about 3.4% under budget. Energy costs and consumption by month are graphically depicted
below.

On December 7, 2011 the Board approved the Renewable Energy Resources Procurement Plan
per Senate bill U2. This plan defines the minimum required percentage of renewables per
compliance period based on total retail energy sales. Compliance periods and percent
renewables are as follows:
Period 1 - January 1, 2011 through December 31, 2013 - 20%
Period 2 - January 1, 2014 through December 31, 2016 - 25%
Period 3 - January 1, 2017 through December 31, 2020 - 33%
Section 3201 (bb) of the CEC regulations define retail sales as: "Sale of electricity by a PUD to
end -use -customers and their tenants measured in MWh. This does not include energy
consumption by a POU electricity used by a POU for water pumping or electricity produced for
onsite consumption (self -generation)." Therefore the retail sales for this calculation is equal to
1421584-71637490=1345457 MWh
