there would much

less comprehension

Can be quickly put into service for contingencies such as another generator suddenly becoming unavailable or if demand for electricity is higher than usual.

TAKEAWAYS

Peakers' plants provide electricity when it's hot, but at the highest price

o Base Load plants are typically steam driven. They operate at 35% efficiency, but

must run at full capacity and are difficult to start up and shut down.

o Peak Load Plants usually use gas turbines. They operate at a lower efficiency,

but can be started up and shut down rapidly.

What is Deregulation? How did it come to pass? In the past the transmission companies controlled the access to

the power which went through its lines.

Deregulation allowed parties other than the transmission companies to have access to the power which went through its lines

Deregulation: The opening of a regulated industry to competition by legislative action.


What caused Deregulation?to occur?

Northeast Blackout (1965) and Three Mile Island (1979) damaged trust in the industry.

Oil Price Shocks (1973, 1979) and the Clean Air Act (1970) encouraged the more efficient use of fossil fuels and development of alternative energy sources

Technological improvement in power generation (combination power plants)

Large price discrepancy in electricity prices across the US suggested price discrimination in the industry


How does the Wholesale marketoperate?

There are three basic types transactions that take place on the

grid

Sale for Resale – Wholesale market

Retail Sale of Electricity or the Retail Market

Wheeling (3rd party charges for use of transmission lines)


How does the Whole sale marketOperate? The Power Exchange


What is the Grid?

Source: Plunkett Report U.S. Electric Grid Enhancements include a Smart Grid, Smart Meters and Flow Batteries Updated 03-13-2014 and Source: Smart Grid and You—The Consumer - NEMA

What is it? It’s electricity with a brain!

It listens, processes, and even responds. Bottom line, it’s all about adding “intelligence” to our aging electric

power infrastructure and delivery systems, from the power plant to the appliances inside your home.

The networks of electric lines that businesses and consumers depend on every day are connected with

and interdependent upon a national network of major lines collectively called “the grid.”

Unfortunately, much of this grid was designed and constructed with technology developed in the

1950s and 1960s, and it was never intended to carry the amazing amount of power that today’s electricity-hungry Americans consume. Simply put, much of the grid is out of date.

What is the SMART Grid?


What is CAISO and how did it come to be?

CAISO was created in 1998 when the state restructured its electricity markets at the recommendation of the Federal Energy Regulatory Commission (FERC), following the passage of the Federal Energy Policy Act of 1992

Removed barriers to competition in the wholesale generation of the electricity business.

The CAISO is regulated by the FERC because interstate transmission lines fall under the jurisdiction of federal commerce laws.


What are the major division ofCAISO?

How does CAISO operate?


Types of Utilities in California

There are 4 basic groups of Utilities Investor Owned Based (IOU) – These are the large utility which

serve thousands of customers, these are public companies which are owned by investors.

2. Municipals - These utilities service a small market area, often a town, city or county.

3. Cooperative/Rural - often serve smaller metropolitan markets or rural areas since not economical for large IOU or Municipals to supply,

4. Federal - These utilities are owned by the federal government.

Renewable Portfolio Standard

It is a commitment to make 33% all energy procured by energy retailers in California renewable by 2020

Who does this cover?

What is it?

Investor owned utilities, energy service providers, small and multi-jurisdictional utilities, and community choice aggregators.

Municipal utilities have a voluntary RPS obligation

The RPS also requires retail sellers to achieve intermediate RPS targets of 20% from 2011-2013 and 25% from 2014-2016.

Note: 20% obligation started in 2010 and continues indefinitely



Established in 2002 under Senate Bill 1078, accelerated in 2006 and expanded in 2011 - California's is one ofthe most ambitious renewable energy standards in the country.

How did it come to be?

Who owns this?

The California Public Utilities Commission (CPUC) and the California Energy Commission (CEC) jointly implement and administers RPS compliance rules for California’s retail sellers of electricity.



California's three large IOUs collectively served 22.7% of their 2013 retail electricity sales with renewable power.

How are we doing?

Since 2003, 8,248 MW of renewable capacity achieved commercial operation under the RPS program. In 2014, 3529 MW of capacity reached commercial operation.

Smart Meters – Starting from dumbAnd getting smarter all the time

A smart meter is a device that can communicate with the utility as well as the consumer’s equipment and records and relays detailed consumption patterns to the utility.

Smart Meter Operation

iles/CNP/Common/SiteAssets/doc/92617

%20energy%20insight%20brochure.pdf

Data is transmitted from the meters to cell relays, which are wireless devices installed on distribution poles.

Cell relays pick up signals from meters in the vicinity and transmit the data via radio to a Take Out Point (TOP).

TOPs collect data from cell relays within a several-mile radius and deliver it to the data center via microwave or fiber optic cable.


Smart MeteringTo keep in mind:

Smart metering does not refer to just the meter. It comprises an entire system capable of functionalities Example load control programs, demand response

Automatic meter reading (AMR) is the technology by which the power consumption data from the metering device is transferred to a central location for further analysis. ONE WAY

Advanced metering infrastructure (AMI)--paved the way for two way communication between the meters and the utility. This feature promises improved operational and energy efficiency, customer service, and environmental protection. TWO WAY


Demand Response

The terms “load management,” “peak load reduction,” and “curtailment” can all be used to describe Demand Response.

“reducing or shifting their electricity usage during peak periods in response to time-based rates or other forms of financial incentives.”

Can applied to consumer and business, typically serviced by difference vendors.

Can be accomplished by a variety of methods: time-of-use pricing, critical peak pricing, variable peak pricing, real time pricing, and critical peak rebates


Demand Response

“What could cause a Demand Response?

Hot for days on end

Cold snap

Weather conditions

Generation facilities are closed


Sequence of a DemandResponse Event


Example of a DemandResponse Event


The Future?I see the following technologies emerging: 1. Distributed Generation2. Small Modular Reactors (SMR)3. Direct Current Cable High Voltage Transmission4. Grid Storage5. “Overgen”


Summary

1. How a utility operates and what a SMART grid is2. Baseline load / what a peaker plant is3. Demand Response4. Smart Meter and Smart Grid5. What is the Renewable Portfolio Standard?6. What was deregulation?7. How electricity is sold in California8. Insight into Trends
