WORKSHOP
To: Board of Directors
From: Steven Poncelet
Date: March 19, 2014
Subject: Review of the 2013 and Projected 2014 Conservation Programs
1. WHY THIS MATTER IS BEFORE THE BOARD
This workshop is before the Board to provide a review of current Conservation Department
energy and water programs, program performance, and to recommend changes and
additions to the FY14 programs.
2. HISTORY
Starting in 2008, the District has been investing in new energy and water conservation
programs and capacity. The current conservation energy and water programs can be
found on our website at www.tdpud.org. As verified and reported through our outside
Evaluation, Measurement, & Verification (EM&V) efforts, the District has a successful track
record of delivering a large portfolio of very cost-effective programs.
The District's conservation program offerings include traditional rebate programs, give-a-
ways, and direct-install programs. The primary goal of the District's conservation programs
remain to maximize return on equity for our customers and to ensure that all of our
customer segments have the opportunity to participate in our programs. Staff has been
working to deliver, and optimize, existing programs and to develop and bring to our
customers new water and energy savings programs.
Historically, our residential energy programs have focused on lighting (screw-in CFL's),
residential energy surveys (comprehensive delivery and installation of energy and water
saving measures), appliance rebates, and low-income. Lighting has dominated our strong
EM&V results. For businesses energy programs, the emphasis has been on commercial
lighting (rebates and free screw-in CFL's/LED's), commercial refrigeration (Keep Your
Cool), and custom projects.
On the waterside, our residential programs have been dominated by water-efficient toilets
(1.6 GPF rebate/exchange), customer leak-rebates (in conjunction with water meters), free
water measures, and water-wise landscaping (Patricia S. Sutton Conservation Garden).
For business water programs, in addition to the residential programs, the emphasis has
been on commercial irrigation and custom water projects.
I
In FY13, the District introduced the following new residential energy programs:
• improved our appliance rebate program by
o the Energy Star rebate to $75 and
o increasing the rebate for more efficient models of refrigerators and clothes
washers according to the Consortium for Energy Efficiency (CEE) Tiers
® Tier 2 $100 rebate
® Tier 3 $125 rebate
• Introduced a residential rebate for screw-in and plug in LED light bulbs ($5/bulb).
For business energy programs, staff implemented a custom rebate program to
accommodate non-lighting technologies.
New water conservation programs include:
• Introduced an incremental $25 incentive to purchase 1.28 GPF or dual-flush high-
efficiency toilets over the standard $100 rebate/exchange incentive for 1.6 GPF
units;
• Introduced an incremental $50 incentive to purchase high water-efficiency clothes
washers (CEE Tiers 2-3) over the applicable energy rebate; and
• Launched the new TDPUD Garden Party and Seminar which included tours of the
Patricia S. Sutton Conservation Garden, local irrigation vendors and experts, and a
seminar featuring a landscape architect and a leading vendor of water-efficient
irrigation equipment.
The District continues to increase our presence in the community with a steady stream of
communication and well established events such as the Tahoe Donner Block Party,
Trashion Shows, TDPUD Garden Party and Seminar, Truckee Thursdays, and the
Truckee Home Show to name a few. Some of the District's most successful programs,
however, are reaching saturation or are being phased out through regulatory actions.
Over time, staff has been analyzing the performance of our programs through the EM&V
process, optimizing existing programs, and investigating potential new programs.
3. NEW INFORMATION
The most recent EM&V results for FY13 showed the conservation programs saving —1.7%
first-year load at a fully loaded cost of —$0.044/kWh (compared to customer cost of
—0.14/kWh to use energy). The Residential Energy Survey's, CFL give-a-ways, Appliance
Rebates, and LED Holiday Light Exchange continue to be the workhorses for the District
residential energy programs. Commercial lighting and refrigeration remain very strong for
business energy programs. High-efficiency toilets, the new HE Clothes Washer Rebate,
and the District's handouts (low-flow shower heads, sink aerators, and hose spray nozzles)
continue to drive the results for water programs. Data on overall conservation program
portfolio and individual program trends is included as Attachment 1..
On balance, the customer demand for energy programs has met or exceeded our budget
and capacity with the overall program being fully subscribed each year. On the waterside,
the residential programs remain very strong, but a need to develop new commercial and
irrigation programs resulted in some unspent funds.
2
In response to staff investigations along with feedback from EM&V, staff is recommending
the following changes or additions to the District's energy and water conservation
programs:
® Develop a new energy program targeting the —1,500 all-electric homes in Truckee.
This program would build upon the existing Residential Energy Survey program, but
would evaluate the cost-effectiveness of deeper energy efficiency retrofits such as
insulation, building envelope improvements, and windows.
® Develop a new water program targeting irrigation systems and controllers and the
larger summer water users in the District.
The goal is to implement these changes in FY14 and to analyze the results in the FY14
EM&V process.
4. FISCAL IMPACT
The approved FY14 budget includes funding for the District's energy and water
conservation programs. There is no direct fiscal impact associated with this workshop
item.
5. RECOMMENDATION
Receive this report and provide feedback to staff.
