AGENDA REPORT
NEW BUSINESS City Manager
Item to be pre:
DATE: May 22, 2001
SUBJECT: ENERGY PROFILE AVAILABLE OPTIONS
DEPARTMENT: Field Services
RECOMMENDED ACTION
City Council direct staff to retain a qualified advisor to assist in providing information regarding
the electric utility industry, and provide guidance on options given the current community energy
profile. Direct staff to conduct a community -wide energy forum to ascertain community values,
needs, and solicit options available regarding this matter. Approve the allocation of $20,000
from Contingency Account No. 1240-7401 to Account No. 5100-8110 to fund related costs.
Authorize City Manager or designee to execute all documents, subject to City Attorney approval.
BACKGROUND
In response to concern expressed by the public and the City Council regarding the reliability and
demand for energy in the Santa Clarita Valley, the City Council directed staff to examine the
current situation and make recommendations as to the options available to our community. It is
apparent that the energy situation in California is highly volatile, the markets and the pricing
remain in flux, and there is great uncertainty as to what tack the Federal and/or State
Government will take to respond to the crisis. Presently, there are over 100 pieces of legislation
in California geared toward "solving" the energy crisis. Many of these proposals have a direct
impact on a municipality's future role in the electric utility industry, and may make or break a
particular strategy.
To date, the City has taken an active role in addressing the energy crisis locally. Such steps
include but are not limited to; an aggressive energy conservation program in all City facilities,
installation of LED lights and complementary battery back-ups at multiple critical intersections,
development of rolling black -out response strategies, outreach to businesses affected by the I-6
rates, participation in local energy summit, and extensive public and legislative outreach
programs. In addition to these items, staff has conducted research on the various options
currently available and potentially available to municipalities in the short and long term. Options
and scenarios reviewed included use of local co -generation plants for power supply, contracting
for electric services via other providers, aggregation, and creation of a municipal utility.

Based on the research conducted, as well as the continued uncertainty of the energy marketplace
coupled with the complexity of the energy issue, it is critical that the City retain uniquely
qualified individuals to assist in gaining an understanding of the current business environment
for the electric utility industry. The advisor would initially conduct a one -day workshop in
which the City Council and other interested stakeholders would be provided with an
understanding of the opportunities and risks faced as an energy industry participant. The advisor
would also assist in the future development of an action plan, and strategic steps to pursue the
options discussed. In addition to these tasks, further research on local energy requirements and
opportunities associated with the existing power generation facilities within the City limits as
well as outside providers would be conducted.
ALTERNATIVE ACTION
Other action as determined by Council
FISCAL IMPACT
A total of $20,000 would be transferred from Contingency Account No. 1240-7401, leaving
$793,387 remaining for future unanticipated expenditures through June 30, 2001

FROM: 61� F F
Assembly Bill 1890: AB 1890 provides the legislative guidance for restructuring of the electric
industry in California. It was signed into law on September 23,1996 as Chapter 854 of the Statutes
of 1996.
Access Charge: A fixed tariff rate that recovers the portion of a utiles transmission revenue
requirement not recovered through the variable Usage Charge.
Aggregator: An entity responsible for planning, scheduling, accounting, billing and settlement for
energy deliveries from the aggregator's portfolio of Sellers (generators, purchases) and/or Buyers
(loads or sales).
All -Electric Service: Electric service for residences having permanently- installed electric heating
facilities and water heaters.
Ampere: The unit of measurement of electric current produced in a circuit by one volt acting through
a resistance of one ohm.
Base Bill: A charge calculated through multiplication of the rate from the appropriate electric rate
schedule by the level of consumption.
Baseload: The minimum amount of electric power delivered or required over a given period of time
at a steady rate.
Biomass: Using solar energy stored in green plants and other organic matter in place of fossil fuels
to power an electric generator. Biomass fuels include wood waste, agricultural wastes, methane
gases from landfills and crops grown specifically for energy production. Using biomass to produce
energy significantly reduces green house gas emissions that would otherwise be produced by these
wastes or fossil fuels.
Btu: The amount of heat energy equal to the quantity of heat required to raise the temperature of
one pound (16 ounces) of water by one degree Fahrenheit.
Bundled or Bundling: Refers to combining components of service, costs or rates into one unit.
Historically, until electric restructuring, electric service was "bundled" and sold for a single price.
Electric restructuring resulted in "unbundling' the elements of service, e.g., generation, transmission,
distribution and metering and billing.
Capacity (Purchased): The amount of energy and capacity available for purchase from outside the
system.
Capacity Charge: An element in a two-part pricing method used in capacity transactions (energy
charge is the other element). The capacity charge, sometimes called Demand Charge, is assessed
on the amount of capacity being purchased.
CARE: California Aftemate Rates for Energy - This program provides a 15 percent reduction in
electric rates for those meeting specific income criteria.
CEC: California Energy Commission - The CEC is a state agency involved in, among other things,
implementing the renewable energy program and certifying renewables generators and ESPs for
the State. For more information, call the CEC at 1-800-555-7794.
Co -generator: A generating facility that produces electricity and another form of useful thermal
energy (such as heat or steam), used for industrial, commercial, heating, or cooling purposes. To
receive status as a qualifying facility (QF) under the Public Utility Regulatory Policies Act (PURPA),
the facility must produce electric energy and another form of useful thermal energy through the
sequential use of energy. And meet certain ownership, operating, and efficiency criteria established
by the Federal Energy Regulatory Commission (FERC). (See the Code of Federal Regulations, Title
18, Part 292.)
Coincidental Demand: The sum of two or more demands that occur in the same time interval.
Coincidental Peak Load: The sum of two or more peak loads that occur in the same time interval.
Combined Cycle: An electric generating technology in which electricity is produced from otherwise
lost waste heat exiting from one or more gas (combustion) turbines. The exiting heat is routed to a
conventional boiler or to a heat recovery steam generator for utilization by a steam turbine in the
production of electricity. This process increases the efficiency of the electric generating unit.
Combined Cycle Unit: An electric generating unit that consists of one or more combustion turbines
and one or more boilers with a portion of the required energy input to the boiler(s) provided by the
exhaust gas of the combustion turbine(s).
Commercial: The commercial sector is generally defined as non -manufacturing business
establishments, including hotels, motels, restaurants, wholesale businesses, retail stores, and
health, social, and educational institutions. The utility may classify commercial service as all
consumers whose demand or annual use exceeds some specified limit. The limit may be set by the
utility based on the rate schedule of the utility.
Commercial Operation: Commercial operation begins when control of the loading of the generator
is turned over to the system dispatcher.
Competition Transition Charge (CTC): as authorized by the CPUC, a charge allowing the
collection of transition costs in a competitively -neutral manner that does not increase rates for any
customer class solely due to the existence of transition costs. [Section 367, AB 1890].
Contract Price: Price of fuels marketed on a contract basis covering a period of 1 or more years.
Contract prices reflect market conditions at the time the contract was negotiated and therefore
remain constant throughout the life of the contract or are adjusted through escalation clauses.
Generally, contract prices do not fluctuate widely.
Contract Receipts: Purchases based on a negotiated agreement that generally covers a period of
1 or more years.
Cooperative Electric Utility: An electric utility legally established to be owned by and operated for
the benefit of those using its service. The utility company will generate, transmit, and/or distribute
supplies of electric energy to a specified area not being serviced by another utility. Such ventures
are generally exempt from Federal income tax laws. Most electric cooperatives have been initially
financed by the Rural Electrification Administration, U.S. Department of Agriculture.
Day -Ahead Market: The forward market for the supply of electrical power at least 24 hours before
delivery to Buyers and End -Use Customers.
Demand -Side Management: The planning, implementation, and monitoring of utility activities
designed to encourage consumers to modify patterns of electricity usage, including the timing and
level of electricity demand. It refers only to energy and load -shape modifying activities that are
undertaken in response to utility -administered programs. It does not refer to energy and load -shape
changes arising from the normal operation of the marketplace or from govemment-mandated
energy -efficiency standards. Demand -Side Management (DSM) covers the complete range of load-
shape objectives, including strategic conservation and load management, as well as strategic load
growth.
Distribution System: The distribution assets of transmission owners that are not under the control
of the ISO and are used to transmit power from the ISO Grid/distribution interfaces to the end user.
EECC: Electric Education Call Center - The EECC is the toll free call center that has been
established as part of the Customer Education Program (CEP) to answer residential and small
business customer concerns about the changes in the electric utility industry. The EECC can be
reached at 1-800-253-0500.

generation, transmission, distribution, or sale of electric energy primarily for use by the public and
files forms listed in the Code of Federal Regulations, Title 18, Part 141. Facilities that qualify as co -
generators or small power producers under the Public Utility Regulatory Policies Act (PURPA) are
not considered electric utilities.
Energy Charge: That portion of the charge for electric service based upon the electric energy
(kWh) consumed or billed.
Energy Deliveries: Energy generated by one electric utility system and delivered to another system
through one or more transmission lines.
Energy Efficiency: Refers to programs that are aimed at reducing the energy used by specific end-
use devices and systems, typically without affecting the services provided. These programs reduce
overall electricity consumption (reported in megawatthours), often without explicit consideration for
the timing of program -induced savings. Such savings are generally achieved by substituting
technically more advanced equipment to produce the same level of end-use services (e.g. lighting,
heating, motor drive) with less electricity. Examples include high -efficiency appliances, efficient
lighting programs, high -efficiency heating, ventilating and air conditioning (HVAC) systems or control
modifications, efficient building design, advanced electric motor drives, and heat recovery systems.
Electric Energy: the generation or use of electric power by a device over a period of time,
expressed in kilowatt-hours (kWh), megawatt -hours (MWh), or gigawatt -hours (GWh).
Energy Receipts: Energy generated by one electric utility system and received by another system
through one or more transmission lines.

industry who buys electric power to be consumed as a final product (not for resale).
Federal Energy Regulatory Commission (FERC): A quasi -independent regulatory agency within
the Department of Energy having jurisdiction over interstate electricity sales, wholesale electric
rates, hydroelectric licensing, natural gas pricing, oil pipeline rates, and gas pipeline certification.
Federal Power Act: Enacted in 1920, and amended in 1935, the Act consists of three parts. The
first part incorporated the Federal Water Power Act administered by the former Federal Power
Commission, whose activities were confined almost entirely to licensing non -Federal hydroelectric
projects. Parts II and III were added with the passage of the Public Utility Act. These parts extended
the Act's jurisdiction to include regulating the interstate transmission of electrical energy and rates
for its sale as wholesale in interstate commerce. The Federal Energy Regulatory Commission is
now charged with the administration of this law.
Federal Power Commission: The predecessor agency of the Federal Energy Regulatory
Commission. The Federal Power Commission (FPC) was created by an Act of Congress under the
Federal Water Power Act on June 10, 1920. It was charged originally with regulating the electric
power and natural gas industries. The FPC was abolished on September 20, 1977, when the
Department of Energy was created. The functions of the FPC were divided between the Department
of Energy and the Federal Energy Regulatory Commission.
FERC: The Federal Energy Regulatory Commission.
Final Day Ahead Schedule: the schedule of generation output/consumption that has been
accepted by the ISO in the day -ahead market.

petroleum-based fuels.
Full -Forced Outage: The net capability of main generating units that are unavailable for load for
emergency reasons.
Generators: Those entities designing, constructing, owning, operating and maintaining generation
assets to supply energy and ancillary services to the competitive market.
Geothermal Plant: A plant in which the prime mover is a steam turbine. The turbine is driven either
by steam produced from hot water or by natural steam that derives its energy from heat found in
rocks or fluids at various depths beneath the surface of the earth. The energy is extracted by drilling
and/or pumping.
Green Power: "Green" power is the commonly accepted term for energy coming from resources
that are renewable through natural processes. Green power is considered to be cleaner than that
produced from traditional generators that use fossil or nuclear fuels. It is cleaner because its
production results in lower air pollution emissions and nuclear waste than electricity from traditional
sources. Renewable, or green, energy is generated from solar, water, wind and geothermal (heat
from the earth) sources and from the burning of biomass (agricultural or other wastes).
Grid: The layout of an electrical distribution system
Grid Management Charge: an approved FERC tariff which recovers the ISO's on-going operating
and management costs.

ISO transmission grid. Its responsibilities include providing non-discriminatory access to the grid,
managing congestion, maintaining the reliability and security of the grid, and providing billing and
settlement services. The ISO has no affiliation with any market participant.
Intermediate Load (Electric System): The range from base load to a point between base load and
peak. This point may be the midpoint, a percent of the peakload, or the load over a specified time
period.
Internal Combustion Plant: A plant in which the prime mover is an internal combustion engine. An
internal combustion engine has one or more cylinders in which the process of combustion takes
place, converting energy released from the rapid burning of a fuel -air mixture into mechanical
energy. Diesel or gas-fired engines are the principal types used in electric plants. The plant is
usually operated during periods of high demand for electricity.
Interruptible Load: Refers to program activities that, in accordance with contractual arrangements,
can interrupt consumer load at times of seasonal peak load by direct control of the utility system
operator or by action of the consumer at the direct request of the system operator. It usually involves
commercial and industrial con summers. In some instances the load reduction may be affected by
direct action of the system operator (remote tripping) after notice to the consumer in accordance
with contractual provisions. For example, loads that can be interrupted to fulfill planning or operation
reserve requirements should be reported as Interruptible Load. Interruptible Load as defined here
excludes Direct Load Control and Other Load Management. (Interruptible Load, as reported here,
is synonymous with Interruptible Demand reported to the North American Electric Reliability Council
on the voluntary Office of Energy Emergency Operations Form OE -411, "Coordinated Regional
Bulk Power Supply Program Report,' with the exception that annual peakload effects are reported
on the Form EIA -861 and seasonal (i.e., summer and winter) peakload effects are reported on the

integrated utilities.
Public Utility Regulatory Policies Act (PURPA): This 1978 Act required electric utilities to
interconnect with and buy capacity and energy offered by nonutilities meeting criteria established by
FERC.
Pumped -Storage Hydroelectric Plant: A plant that usually generates electric energy during peak -
load periods by using water previously pumped into an elevated storage reservoir during off-peak
periods when excess generating capacity is available to do so. When additional generating capacity
is needed, the water can be released from the reservoir through a conduit to turbine generators
located in a power plant at a lower level. (Stored energy— battery)

when energy from another electric system is acquired and it varies from a specified unit base
amount.
Pure Pumped -Storage Hydroelectric Plant: A plant that produces power only from water that has
previously been pumped to an upper reservoir.
Qualifying Facility (OF): A co -generation or small power production facility that meets certain

(See the Code of Federal Regulations, Title 18, Part 292.)
Rate Base: The value of property upon which a utility is permitted to earn a specified rate of return
as established by a regulatory authority. The rate base generally represents the value of property
used by the utility in providing service and may be calculated by any one or a combination of the
following accounting methods: fair value, prudent investment, reproduction cost, or original cost.
Depending on which method is used, the rate base includes cash, working capital, materials and
supplies, and deductions for accumulated provisions for depreciation, contributions in aid of
construction, customer advances for construction, accumulated deferred income taxes, and
accumulated deferred investment tax credits.
Regulation: The governmental function of controlling or directing economic entities through the
process of rulemaking and adjudication.
Renewable Resources: Renewable resources for the production of electricity are wind, solar,
water (small hydro), biomass (the burning of agricultural or other wastes) and geothermal (earth
heat). These resources are considered renewable because they do not run out or they quickly
renew themselves by natural processes.
Residential: The residential sector is defined as private household establishments which consume
energy primarily for space heating, water heating, air conditioning, lighting, refrigeration, cooking and
clothes drying. The classification of an individual consumers account, where the use is both
residential and commercial, is based on principal use. For the residential class, do not duplicate
consumer accounts due to multiple metering for special services (water, heating, etc.). Apartment
houses are also included.
Restructuring Trusts: the two tax-exempt public benefit trusts established by the CPUC to provide
for the design and development of hardware and software systems for the Power Exchange and the
Independent System Operator.
Retail: Sales covering electrical energy supplied for residential, commercial, and industrial end-use
purposes. Other small classes, such as agriculture and street lighting, also are included in this
category.
Scheduled Outage: The shutdown of a generating unit, transmission line, or other facility, for
inspection or maintenance, in accordance with an advance schedule.
Scheduling Coordinators (SC's): submit balanced schedules and provide settlement -ready meter
data to the ISO. They are similar to a private/investor owned equivalent to the PX. Scheduling
Coordinators may also:
— Settle with generators and retailers, the PX and the ISO
— Maintain a year-round, 24-hour scheduling center
— Provide non -emergency operating instructions to generators and retailers
The PX is considered a Scheduling Coordinator and provides the spot market into which other SC's
can buy or sell to balance their schedules.
Senate Bill 477: SB 477 was a companion or follow-up bill to AB 1890. It added many consumer
protections by establishing stronger ESP registration requirements and enabling the Commission to
accept, investigate and help resolve complaints against ESPs. It also required a standard bill format
and disclosure of prices, terms and conditions of service for residential and small commercial
customers and authorized ORA to use the disclosures to help consumers understand and evaluate
service offers.
Small Power Producer (SPP): Under the Public Utility Regulatory Policies Act (PURPA), a small
power production facility (or small power producer) generates electricity using waste, renewable
(water, wind and solar), or geothermal energy as a primary energy source. Fossil fuels can be used,
but renewable resource must provide at least 75 percent of the total energy input. (See Code of
Federal Regulations, Title 18, Part 292.)
Solar: Electricity produced by sources that collect energy from the sun. Examples of solar power
are: photovoltaic panels, which are semiconductors that directly generate electricity, and solar
thermal plants that use the sun to create steam to tum a turbine.
Spot Purchases: A single shipment of fuel or volumes of fuel, purchased for delivery within 1 year.
Spot purchases are often made by a user to fulfill a certain portion of energy requirements, to meet
unanticipated energy needs, or to take advantage of low -fuel prices.
Steam -Electric Plant (Conventional): A plant in which the prime mover is a steam turbine. The
steam used to drive the turbine is produced in a boiler where fossil fuels are burned.
Stranded Costs: Long term capital debt originating before and extending after the point of
deregulation.
System (Electric): Physically connected generation, transmission, and distribution facilities
operated as an integrated unit under one central management, or operating supervision.
System Power: This is the traditional electricity mix that you would get if you did not switch from
your UDC (Utility Distribution Company). It currently consists of approximately 17% coal, 24% large
hydroelectric, 35% natural gas, 14% nuclear and 11 % eligible renewables.
Tariff: a document filed with the appropriate regulatory authority specifying lawful rates, charges,
rules, and conditions under which the utility provides services to parties. A tariff typically includes
rates schedules, list of contracts, rules and sample forms.
Time of Use: This rate option allows customers to purchase electricity on a rate schedule reflecting
their usage in real time (hour by hour) based on the PX price. Consumers may potentially lower their
costs by shifting their usage to "non peak' hours when electricity is available at a lower rate. In most
cases, this requires the purchase of a special meter.
Transition Period: the period of time to allow IOUs and Local Publicly -Owned Utilities an
opportunity to continue to recover costs for generation -related assets and obligations that may not
be recoverable in market prices in a competitive generation market. The period was defined as
January 1, 1998 through December 31, 2001.
Transmission: The movement or transfer of electric energy over an interconnected group of lines
and associated equipment between points of supply and points at which it is transformed for
delivery to consumers, or is delivered to other electric systems. Transmission is considered to end
when the energy is transformed for distribution to the consumer.
Transmission System (Electric): An interconnected group of electric transmission lines and
associated equipment for moving or transferring electric energy in bulk between points of supply
and points at which it is transformed for delivery over the distribution system lines to consumers, or
is delivered to other electric systems.
Unbundled Rates: separate line -item charges for generation, transmission, distribution, and other
services and programs.
