WORKSHOP
To: Board of Directors
From: Steven Poncelet
Date: March 17, 2010
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 an informational review of the District's 2009 Evaluation,
Measurement, & Verification (EM&V) results.
2. HISTORY
The District continues to make significant investments in the Conservation Department
and our energy efficiency programs and remains a leader in energy efficiency program
results. As part of the District's regulatory reporting through the Northern California
Power Agency (NCPA), the Conservation Department is required to perform an EM&V
study on the FY09 energy efficiency program results and to project results for FY10.
The District's results are then aggregated with all of public power in California into one
report submitted jointly with the California Municipal Utilities Association (CMUA). This
consolidated report is due each year on March 15th.
3. NEW INFORMATION
The EM&V report for FY09 program results, the FY10 program projections, and an
executive summary have been completed and submitted to NCPA as part of our
California Energy Commission (CEC) SB1037/AB2021 reporting requirements. The
executive summary is included as Attachment 1 and gives the overall results of the
District's energy efficiency programs, a description of our current key activities, and a
summary of the District's program offerings.
NCPA is compiling this information, along with information from all of the Publicly
Owned Utilities (POU's), into a final report that is due to the CEC on March 15th. Final
FY09 results for the Conservation Department include spending -4.5% of retail sales
on public benefit and energy efficiency programs resulting in first-year reduced energy
usage of almost 2.5% for the FY09 programs (first-year net annual kWh savings of
3,575,636 kWh, net life cycle kWh savings of 34,528,706 kWh, net peak kW savings
of 898 kW, and a TRC of 5.06).
To put these results in perspective, the District is in the top five of all electric utilities in
California when measured by percent load reduction and for cost-effectiveness of
programs. When the life cycle energy savings are divided by the FY09 cost to the
District to deliver these programs (direct measure costs plus fully loaded labor), the
result is a cost to the customer of 1.9 cents/kWh (which is a fraction of the District's
purchase power costs and over 80% lower than the cost to the customer to use
energy). A review of the FY09 EM&V results gives the Board an opportunity to
evaluate the design, implementation, and cost effectiveness of the Conservation
Department's energy efficiency programs.

TRUCKEE DONNER PUBLIC UTILITY DISTRICT
Public Utility District
• Established in 1927
• 13,154 customers,88 percent are residential
• TDPUD projects an average growth rate of 1 percent per year,for the next 10 years
• 2009 Peak demand—35.9 megawatts(winter peaking)
• 2009 Energy Use—146.9 gigawatt-hours
TDPUD Energy Efficiency Program Highlights
• In 2009,the Truckee Donner Public Utility District(TDPUD)continued to make significant
investments in our Public Benefits and energy efficiency programs. This includes increasing
Public Benefit and energy efficiency spending to—4.5%of gross electric sales in calendar year
2009 with a calendar year 2010 budget of—4.5%of gross electric sales. In 2009,the TDPUD's
energy efficiency results included a first year energy savings of almost 2.5%of gross electric
sales with a TRC of over 5.
• In 2009,the TDPUD developed 7 new energy efficiency programs (for a total of 16)that
expanded our offerings to businesses and income qualified customers and continued to serve
our residential base. 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.
• The economic crisis during 2009 had a major impact on our energy efficiency programs as
customers struggled to make ends meet. On the positive side,the TDPUD's 'save energy,save
money' message had much more traction with our customers. However,the customer's ability
to make the investments necessary to implement cost effective energy efficiency projects was
diminished. This was particularly true with our commercial and small business customers. To
address this,the TDPUD focused on direct-install and give-a-way programs. The American
Recovery and Reinvestment Act of 2009(ARRA)was one opportunity to address the economic
crisis but, due to the design and implementation of the stimulus money,the TDPUD was
precluded from participating in a meaningful way. This was due to the fact that the majority of
the money was distributed to cities and counties(of which the TDPUD is neither)and the
competitive opportunities through the California Energy Commission's State Energy Program
and the Department of Energy were not designed for smaller utilities grant applications.
• The TDPUD updated our 10-year energy efficiency targets in early 2010 as part of the
SB1037/AB 2021 requirement. For the period from 2011 through 2020,the new energy savings
target is: 19,880 MWh (-1.1% per year). This is a significant increase from the first energy
190
savings targets, established in 2007,of 10,1014MWh (^.67%per year). The new aggressive
targets take into account the TDPUD's strong past energy efficiency results. However,the new
targets also recognize that past results were heavily influenced by lighting programs which the
TDPUD is beginning to saturate and which, unfortunately, are being unfairly discounted by the
regulatory bodies.
2009 Highlights Include:
• Implemented programs with the potential to reduce electric usage by almost 2.5% in the first
year. 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 2009
programs and completed the final EM&V report within 2-months of calendar year 2009 end.
The EM&V report concluded: Net Annual kWh Savings of 3,575,636 kWh, Net Lifecycle kWh
Savings of 34,528,706 kWh, Net Peak kW Savings of 898 kW,and a TRC of 5.06.
• 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.
• Developed a new income qualified program, Energy Saving Program (ESP),targeting residential
energy efficiency and weatherization measures. This innovative new program provided a one-
time bill credit for the customers largest bill in the last 12-months (up to$200) but also required
that the customer participate in a free energy survey of their home and that they agree to install
energy conservation measures provided for free at the time of the survey(CFL's, piping/water
heater insulation, door sweeps, etc.). To implement the program,the TDPUD partnered with a
local non-profit(Family Resource Center)to do the outreach and qualification for the program
and worked with the Sierra Green Building Association (SIGBA)to conduct the residential energy
surveys. ESP was very successful in providing immediate assistance during the economic crisis,
enabled the customer to reduce energy usage over time, and strengthened the TDPUD's
relationship with our low-income customers and the overall community.
• 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—6 percent customer participation over a 4-
week period and all of the customers came to the TDPUD office where they were educated,
provided with free CFL's,and given information on other energy efficiency opportunities.
2009 Commercial Customer Programs
• 'Keep Your Cool' Commercial Refrigeration Program: This direct-install program was developed
by the Northern California Power Agency(NCPA)for their member utilities and targets cost-
effective commercial refrigeration measures(door gaskets and closers). This program was
oversubscribed in the first-round and the TDPUD added additional budget to this program in
2009 to meet robust customer demand.
191
• Commercial LED Exit Sign Retrofit Program: This direct-install program was developed by the
TDPUD to retrofit existing incandescent and fluorescent exit signs using high-efficiency LED exit
sign retrofit kits. The combination of low retrofit cost and ease of installation created a very
cost effective program.
• Commercial Energy Audits: TDPUD offers free on-site energy audits conducted by a TDPUD
Energy Specialist for commercial customers that provide specific recommendations on cost-
effective energy improvements to manage and reduce energy use and load.
• Commercial Energy Conservation Rebate Program: TDPUD provides a comprehensive
commercial energy efficiency incentive program;focusing on peak load reduction and energy
savings.Generous rebates and technical support are available to commercial customers to
promote the installation of energy efficiency measures.This includes an appliance efficiency
program for clothes washers, dishwashers and refrigerators;a building efficiency program that
includes building envelope and forced-air distribution system leak testing and mitigation; a
lighting efficiency program that includes any and all high efficiency lighting measures;space
heating system efficiency program including ground source heat pumps and a water heating
efficiency program including the purchase of energy efficient electric water heaters and solar
water heater tanks.
• Solar PV Program: TDPUD offers financial incentives to commercial customers who incorporate

2009 Business Partnership Programs(Green Partners)
• Retail:TDPUD encourage restaurants to install energy-efficient lighting and other energy
efficiency measures. The District also works with and encourages local hardware and grocery
stores to market,sell and install energy-efficient products and services.
• Restaurant: Encourage restaurants to install energy-efficient lighting,cooking, dishwashing, and
heating,ventilation and air conditioning equipment.
• Hospitality: Encourage hotels, motels,and resorts to implement LEED design principles and
energy-efficient lighting,controls, HVAC,water heating, pool/spa, restaurant, renewable energy
and green building technologies.
2009 Residential Customer Programs
• Developed a new income qualified program, Energy Saving Program (ESP),targeting residential
energy efficiency and weatherization measures(see 2009 Highlights above).
• Residential Green Partners: This new 2009 program was focused primarily on screw-in lighting
with a goal to determine which types of lighting(beyond standard spiral 60-watt equivalent
CFL's)are used most in our community and to provide free samples of this lighting for our
customers. Based on data from over 300 customers and over 3000 screw-in lights (over 20
types ranging from can lights to globes to flame tips to outdoor lights to dimmables). Based on
the data collected,the TDPUD is now handing out, in addition to 12-packs of 60-watt equivalent
CFL's,the following lights: 40-watt equivalent globes (G25's),50-watt equivalent R20's, 65-watt
equivalent floods (R30's), 65-watt equivalent dimmable floods (DR30's),90-watt equivalent
192
outdoor floods (PAR30's), and 100-watt equivalent CFL's. This program is in addition to the
rebate program that the TDPUD has for high-efficiency lighting.
• Portable/Take Home Energy Meters: Using the'Kill-A-Watt' portable energy meters,this new
2009 program allows customers to sign out a watt meter for a 2-week period to measure the
energy use of their residential plug loads (from refrigerators to electronics). The TDPUD then
helps the customer understand the data and identify cost-effective energy efficiency
opportunities.
• Residential Energy Audits: TDPUD offers free on-site energy audits,conducted by a TDPUD
Energy Specialist,that provide specific recommendations on cost-effective energy
improvements to manage and reduce energy load and provided savings.
• Residential Energy Conservation Rebate Program: TDPUD provides a comprehensive residential
energy efficiency incentive program,focusing on peak load reduction and energy savings.
Generous rebates and technical support are available to residential customers to promote the
installation of energy efficiency measures.This includes an appliance efficiency program for
clothes washers, dishwashers and refrigerators; building efficiency program includes building
envelope and forced-air distribution system leak testing and mitigation; residential CFL's
efficiency program including a multi-family unit CFL light bulb give away;space heating system
efficiency program includes ground source heat pumps and the water heating efficiency
program includes the purchase of energy efficient electric water heaters and solar water heater
tanks.
• Low-Income Weatherization: In addition to the new ESP program described above in the 2009
highlights,the TDPUD provides home energy weatherization services to low-income residential
customers along with targeting this customer base for lighting and other give-a-ways by working
with local non-profits and agencies.
• Solar PV Program: TDPUD offers financial incentives to residential customers who incorporate
solar PV technologies into their homes (SB-1). This program is fully subscribed into 2011.
2009 Community Programs
• Energy Conservation & Efficiency Workshops:TDPUD staff offered numerous energy
conservation and efficiency seminars and workshops in 2009.
• Million CFL Program:The Million CFL program is a 10-year program starting in 2008 designed to
provide incentives and CFL give-a-ways that will result in significant lighting efficiency savings.
All CFL give-a-ways are done face-to-face allowing for education of the customer and promotion
of other programs.
• LED Holiday Light Swap Program:The District began an LED (light emitting diode) Holiday Light
swap program in 2007.The program involves giving District customers up to three strands of
LED holiday lights in exchange for their old inefficient holiday lighting. In 2009,this cost-
effective program served —6%of our customer base in a 4-week period. In additional, all of
these customers visited our Conservation Department to participate in the program where the
TDPUD educated them on the many other energy savings opportunities and handed out free
CFL's.
193
• Green Building Education/Installer:TDPUD has partnered with the local Sierra Green Building
Association and the Town of Truckee Green Building Committee to design and implement green
building education and training programs for the Truckee-Tahoe communities.
• Green Buildings Tour:TDPUD works with the Sierra Green Building Association and local groups
to provide tours of buildings in the community that incorporate green building design features.
2009 Education Programs-Public Schools&Community:
• Energy Education: A TDPUD personnel gives presentations on energy topics to local schools
each year.
• "Living Wise" Resource Efficiency Program: TDPUD collaborates with the 6th grade staff at the
local middle school to provide the curriculum and resources for the"Living Wise" Resource
Efficiency program.
• Green Building Symposium:TDPUD helps organize and conducts a presentation at the Truckee
Home Show's Green Building Symposium.
2009 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 2010 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.
2009 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.
2009 TDPUD Water Conservation Programs:
The TDPUD serves both water and electric power services to our customers. In fact,the TDPUD's largest
electric customer is the TDPUD Water Department and we fully understand the links between water
conservation and energy savings for both ourselves and our customers. Current water conservation
programs include:
• TDPUD Water Wise Demonstration Garden:TDPUD began installing residential water meters in
2009 and will begin billing water by usage in 2010. For many customers,water usage is driven
by landscaping and irrigation. To help our customers manage their irrigation use,TDPUD
developed a water wise demonstration garden at our main headquarters to educate our
customers on techniques to maintain beautiful landscaping and save water. The garden
includes almost 100 native and drought tolerant plants along replacing our traditional lawn with
a variety of native bunch grasses that can use 80% less water.
194
• Commercial Water Conservation Rebate Program:TDPUD offers rebates to commercial
customers for the installation of water-saving measures including water-efficient clothes
washers. Additional water-efficient investments including low-flush toilets;waterless urinals
and other water saving devices may soon be eligible for this rebate.
• Residential Water Conservation Rebate Program:TDPUD offers financial rebates to residential
customers for the installation of water-saving measures including water-efficient clothes
washers. TDPUD also hands out for free low-flow showerheads and sink aerators. New for 2009
was a Customer Leak Repair Rebate Program that incents customers to repair leaks on the
customer-side of the meter. Additional water-efficient investments including low-flush toilets
and other water saving devices will soon be eligible for this rebate.
Landscape Water Conservation Workshops:TDPUD partnered with local nurseries to conduct landscape
water conservation workshops for the community.
