Port of Oakland Energy Efficiency Program Highlights
Current Commercial Programs:
• Energy Audits: The Port with the collaboration of City Of Oakland is currently conducting an
Energy Audit program that will result in recommendations of major energy saving
retrofit/improvement projects that could be undertaken to effectively support load reduction
and the more efficient use of energy in the area. Rebates will be provided for the energy
efficiency projects completed based on the energy audit recommendations. The energy audit is
provided to the Port's customers free of charge.
• Energy Saving Measures Exceeding Title 24 Standards: Port will provide a rebate for any new
facility constructed within the Port by its electricity customers that exceed the title 24 standards
in energy saving measures. Eligible facility must reduce energy usage by a minimum of 10%
compared to the standard title 24 facility. This rebate will pay for a percentage of the cost
difference between a standard and an upgraded title 24 equipment (such as HVAC units) and
material.
• Energy Saving Equipment Retrofits/Improvements Rebates: The Port has implemented a
program that provides generous rebates and solid technical support for the installation of new
energy efficient equipment/improvements by our commercial customers. Under our program,
the eligible projects must reduce energy usage by a minimum of 20 percent, to be eligible for a
rebate of the equipment cost differential (up to a 90 percent rebate for energy saving of 90
percent or more).
• Lighting Retrofit: A program providing rebates for the installation of energy efficient lighting
that reduces annual energy usage by at least 35 percent in commercial facilities. This rebate is
based on a single flat incentive rate of $0.05 per annual kilowatt‐hours saved.
• Energy Saving / Efficiency Research, Development, and Demonstration Programs: Port
electricity customers that do research, development and demonstrate new energy
saving/efficiency programs are entitled to a rebate up to 20% of the cost of a project based on
availability of funds. To qualify for a rebate under this program all Energy Savings/Efficiency
Research, Development and Demonstration Programs must be based on environmental friendly
natural resources (or waste products).

Port of Oakland Renewable (or Green) Energy Programs:
• Photovoltaic (PV) Power Generating Systems In Accordance with Senate Bill 1 (SB1): Beginning
January 1, 2008, this rebate will reimburse new solar energy generating facilities a onetime flat
rate of $ 3.50 per watt (Alternating Current) of installed capacity. In the event the new solar
facility generates more than the electric customer’s monthly electric consumption, then the Port
will purchase the excess solar electric power from said facility at the same rate the Port sells
power to said facility. In addition, the new solar energy generating facilities must obtain Port
approval and must comply with all regulatory requirements prior to the construction of the
facility. This rebate is subjected to 7% annual reduction per SB1.
• Other Renewable (or Green) Energy Programs: Beginning January 1, 2008, this rebate will
reimburse new clean wind energy generating facilities that generates over 7.5 kilowatts a
onetime flat rate of $ 1.50 per watt (alternating current) of installed capacity and if the facility
generates less than 7.5 kilowatts then the rebate will be a onetime flat rate of $ 2.50 per watt
(alternating current) of installed capacity. In the event the new wind power facility generates
more than the electric customer’s monthly electric consumption, then the Port will purchase the
excess electric power from said facility at the same rate the Port sells electric power to said
facility. In addition, the new wind power energy generating facilities must obtain Port approval
and must comply with all regulatory requirements prior to the construction of the facility. All
other renewable generation that qualify under this program are given a maximum rebate of 20%
of the construction cost of the generating facility, based on the availability of funds.
Port of Oakland Demand Reduction Programs:
The Port of Oakland does not currently have any demand reduction programs in place.

RANCHO CUCAMONGA MUNICIPAL UTILITY
The Rancho Cucamonga Municipal Utility (RCMU) was formed in 2001 to provide safe, reliable and cost‐
effective electric service to retail customers that were building new facilities located within the
designated service territory. It served its first customers in 2003. Annually, more than 72,000
megawatt‐hours of electricity are distributed to our customers via 20 circuit miles of wire spread across
approximately 4 square miles. Its historical peak demand is 17.5 megawatts, set in August 2011. RCMU
currently serves no residential customers but has over 480 commercial accounts, many of which are
smaller, privately owned businesses. RCMU also services the City of Rancho Cucamonga’s City Hall,
Cultural Center, Victoria Gardens Library, Animal Center, and the city’s Epicenter Entertainment and
Sports Complex.
Energy Efficiency Program:
In fiscal year 2010/2011, RCMU issued $29,621 in lighting rebates, which will save an estimated 211,663
kWh/year. The majority of the savings are due to one national department store replacing 2,702
incandescent lights with LEDs. Staff believes that due to the continuing difficult economic conditions,
which are putting a strain on the cash flows of small businesses, there is reluctance among many RCMU
customers to participate in programs with any upfront monetary costs; therefore, staff is continuing to
explore programs and incentives that will accommodate this trend.
RCMU is also exploring new ways to advertise their rebate program and energy efficiency information to
their small business community. A quarterly newsletter and free energy audits are currently utilized to
educate customers on current rebates and energy efficiency updates. RCMU has partnered with a
contractor who works with a non‐profit organization that is dedicated to retraining displaced workers in
the new “green” economy. The students of the non‐profit are all BPI and HERS‐II certified and many
already posses a contractor’s license. To date, one student from the non‐profit has been fully employed
by the contractor. Through this partnership RCMU is offering free energy audits to all its customers and
hopes to expand the program in the future.
Commercial Customer Programs:
• Incentives/Rebates: RCMU has adopted the “Express Solutions” model for energy efficiency
rebates. RCMU does not restrict customers to specific technologies or approved models of
equipment; customers can elect to install any energy efficient improvement they wish.
Customers receive a rebate for estimated kilowatt hour savings for the first year. RCMU uses the
following categories and incentive rates:
Category Annual Consumption Reduction Rebate Lighting $.05/kwh Refrigeration $.09/kwh HVAC $.09‐$.15/kwh Motors $.09/kwh Other $.09/kwh
• Energy Audits: RCMU offers free, customized energy audits including lighting assessment, HVAC
assessment, equipment assessment and a review of energy usage. Specific cost‐effective
recommendations to improve energy efficiency and reduce energy use are provided.
• Time of Use Rates: All customers whose demand exceeds 200 kilowatts receive time‐of‐use
pricing, incentivizing them to reduce their energy costs through the effective time management
of their energy usage.
Renewable Energy Programs:
Currently, RCMU has two solar photovoltaic customers which are estimated to save a total of 105,049
kWh/year. For calendar year 2012, RCMU is continuing to offer the 2011 incentive of $2.25 per watt
installed for renewable energy generation systems with a peak AC output of less than 30 kW, and $0.08
per kilowatt hour produced for renewable energy generation systems with a peak AC output of 30 kW or
more. By maintaining the 2011 solar incentive rates RCMU hopes to encourage more businesses to
invest in renewable energy. These incentives are capped at 50% of total system installation cost. RCMU
is also currently waiving all RCMU‐related plan check and inspection fees.
Demand Reduction Programs:
In 2012 RCMU has partnered with Southern California Public Power Authority (SCPPA) and Ice Energy to
install the thermal energy storage product called the Ice Bear. The system stores and produces ice
during the off peak hours of the night and then works to cool the building through its existing HVAC
system during the peak hours of the day. RCMU hopes to reduce electric system demand during the
critical hours of the day to help ensure overall system reliability.
RCMU has also hired a consultant to conduct a smart grid study in 2012. This study will gather and
analyze data, economic values and technical considerations necessary to determine the requirements
and feasibility of a potential smart grid deployment in our service territory.
In addition, two City facilities within RCMU’s service territory have installed emergency back‐up
generation systems which can be utilized when the need arises. These generators are capable of
supplying the power needs for these two facilities for 24 hours. These two facilities are also two of
RCMU’s largest customers.
