Public Utility District
WORKSHOP
To: Board of Directors
From: Steven Poncelet
Date: March 18, 2009
Subject: Discussion of the Progress in Energy Savings
1. WHY THIS MATTER IS BEFORE THE BOARD
The Board plays a key role in the District's conservation and energy efficiency
programs through goal setting, budgetary approval, and critical feedback on the
programs. This item is a informational review of the Districts 2008 Evaluation,
Measurement, & Verification (EM&V) results along with the a detailed summary of the
energy saving from the completed Truckee Senior Center project.
2. HISTORY
The District has made significant investments in the conservation department in FY08
including an aggressive suite of new programs, new staff, and increased marketing
and outreach. As part of the District's regulatory reporting through the Northern
California Power Agency (NCPA), the Conservation Department is required to perform
and EM&V study on the FY08 actual results and project results for FY09. One of the
projects included in this analysis was the Low-Income Senior Center weatherization
project completed in October of 2008 in partnership with Nevada County and the
property manager.
3. NEW INFORMATION
The EM&V report for FY08 program results, the FY09 program projections, and an
executive summary have been completed and submitted to NCPA as part of our
California Energy Commission SB1037 reporting requirements (the executive
summary is attached). NCPA is compiling this information, along with similar
information from other member public owned utilities, into a final report to be
submitted to the CEC on or prior to the March 16, 2009 deadline. Final FY08 results
for the Conservation Department include spending —4% of gross electric sales on
public benefits and energy efficiency programs resulting in reduced energy usage of
3% (Net Annual kWh Savings of 4,455,607 kWh, Net Lifecycle kWh Savings of
36,792,306 kWh). When these life-time energy savings are divided by the FY08 cost
to the District to deliver these programs, the result is a cost to the customer of 1.3
cents/kWh (which is a fraction of the District's average power purchase cost and one-
tenth of the customer's usage rate).
The District also continues to monitor the energy usage of the Senior Center to track
the results of the significant weatherization program by comparing current against
historical usage. Results for the recent winter months indicate reduced energy usage
of 20 to 30%. A review of the FY08 EM&V results and the Senior Center project gives
the Board an opportunity to evaluate the design, implementation, and cost
effectiveness of the Conservation Department's public benefits and energy efficiency
4. FISCAL IMPACT

TRUCKEE DONNER PUBLIC UTILITY DISTRICT
Public Utility District
• Established in 1927
• 13,155 customers, 88 percent are residential
• TDPUD projects an average growth rate of 1-3 percent per year, for the next 10 years
• 2008 Peak demand —35.1 megawatts (winter peaking)
• 2008 Energy Use—148.3 gigawatt-hours
TDPUD Energy Efficiency Program Highlights
• In 2008, the Truckee Donner Public Utility District (TDPUD) made significant investments in
our Public Benefits and energy efficiency program's and staff capacity. This includes
elevating energy efficiency to a management level position with the creation of a
Conservation Manager position and increasing Public Benefit and energy efficiency
spending to—4 percent of gross electric sales in calendar year 2008 with a calendar year
2009 budget of—5 percent of gross electric sales. The TDPUD targeted the most cost-
effective programs and partnered with local agencies, businesses, and community groups
to effectively implement programs. The TDPUD is seeing increasing acceptance of the
economic and community benefits of energy efficiency investments.
2008 Highlights include:
• Implemented programs with the potential to reduce electric usage by—3 percent annually.
This result greatly exceeds our target of 0.675 percent per year over 10-years established
as part of the reporting requirements. The District was able to achieve this performance
through a combination of cost-effective measures (mostly lighting), effective program
management, and leveraging the District's position within the community.
• Created an Evaluation, Measurement, &Verification (EM&V) Plan for calendar year 2008
programs and completed the final EM&V report within 3-months of calendar year 2008
end. The EM&V report concluded: Net Annual kWh Savings of 4,455,607 kWh, Net
Lifecycle kWh Savings of 36,792,306 kWh, Net Peak kW Savings of 927 kW, and a TRC of
7.12.
• Effectively delivered programs for a cost of less than one quarter of the District's power
purchase costs and a fraction of the customer's rate.
• Significant investments in community outreach, communications, and marketing are
tapping increasing interest in energy efficiency programs. As an example,the TDPUD's
recent LED (Light Emitting Diode) Holiday Light Program achieved —5 percent customer
participation over a 5-week period and all of the customers came to the TDPUD office
where they were educated and given information on other energy efficiency opportunities.

2008 TDPUD Website
The TDPUD continues to improve our website and conservation/energy efficiency pages that are
an on-line resources to our customers regarding programs, rebates, application information, and
local resources. The TDPUD is going to upgrade its website in 2009 with a Power of Conservation
focus and an on-line energy efficiency competition. There will be many new enhancements added
to the website that will go a long way in promoting energy efficiency, conservation and
renewables.
2008 TDPUD Demand Reduction Programs
The TDPUD does not currently have any demand reduction programs in place since there is very
little air conditioning load and the TDPUD high demand time is winter. However, many of our
energy efficiency programs address our unique load profile.
2008 Wires-to-Water Efficiency Program
In 1998,TDPUD staff started a review and testing program for all of the wells and pumping
facilities in the district. It was determined that all of the water pumping and well facilities were
not energy efficient. After the initial evaluation, an efficiency standard was developed to provide
guidance in meeting the long term goal of energy efficient delivery of water.
From 2001 to the present, existing facilities were rebuilt with higher efficiency pumping systems
than would have normally been purchased. This is an ongoing project and the TDPUD will
continue to evaluate the energy efficiency gains and cost effectiveness of this program. Measured
energy savings for this program are based on the following system-wide results:
2001: Baseline annual energy use - 5,586 kilowatt-hours per MG
• 2006: Improvements reduced usage to—4,688 kilowatt-hours per MG (2,370 MG total)
• 2007: Improvements reduced usage to—4,612 kilowatt-hours per MG (2,433 MG total)
2008: Improvements reduced usage to—4,484 kilowatt-hours per MG (2,303 MG total)
