Overview

What is the Water Energy Nexus?

Why is it important to system reliability.

What you can do to assure system reliability.


SM

Water-Energy Nexus

The interdependencies among water and energy resources and infrastructure. At a policy level, California considers the scope of its water-energy nexus to include climate-related impacts, including greenhouse gas emissions.

Since the California Energy Commission (CEC) issued its landmark finding in 2005. The Water-Energy Team of the Climate Action Team (WET-CAT) adopted and is

implementing a multi-agency water-energy strategic plan. The CEC has increased requirements for water and energy efficiency in buildings

through revisions to the California Building Standards Code.2 California Department of Water Resources now requires consideration of the

water-energy nexus in competition for Integrated Regional Water Management Planning grants, and has also included elements of the state’s water-energy-climate nexus in the California Water Plan.

The CPUC directed the state’s energy investor-owned utilities (IOUs) to include the water-energy nexus in their 2013-2014 Energy Efficiency portfolios.

The Water And Power Partnership

• Water represents nearly 20% of the electricity consumed in the state

• Energy costs are a significant portion of most water agency budgets

• AB 32 impacts

Parallel Concerns


Cost of Service is Increasing Faster Than Energy Sales Resulting in Higher Customer Rates

Cost of Service

Energy Sales

Public policy is driving up the cost of energy; additional investments are needed for grid reliability

Energy efficiency and distributed generation offer customers options to better manage usage and avoid escalating rates

Environmental Considerations

Balance objectives through CPUC/CEC’s “loading order”:

– Energy Efficiency; Demand Response

– Renewable Resources; Distributed Generation

– Clean and Efficient Fossil-Fired Generation

The LA Basin: Challenges And Potential Solutions

Recent studies show need for 2400-3600 MW of “West LA Basin” to replace OTC plants

Local transmission grid (220kV) runs from the coast to serve load

Re-powering at beach sites may face stiff opposition

LA Basin is a non-attainment area and AQMD rule 1304 is one of the few sources of emissions offsets for new generation

Forces Influencing Southern California Infrastructure Development

The Role of Nuclear Energy in California

San Onofre provides “baseload” generation – 24 hours a day, 7 days a week, regardless of weather conditions, unlike wind and solar.

Nuclear energy provides voltage support, which keeps the electrons moving through the grid across the region.

Nuclear energy is by far the largest source of carbon-free generation and in 2011, provided 24 percent of SCE’s electricity generation mix.

37 percent of the state’s emission-free power generation is supplied by nuclear energy facilities that can produce large amounts of electricity day and night, and without constraints.

How SCE Can Help

Technical assistance to identify and evaluate projects Free energy audits, pump efficiency testing, and engineering

evaluations Free training classes/workshops

Incentive funding for qualifying projects Energy Efficiency: both new construction and replacement Demand Response: both new construction and replacement Self Generation: solar, wind, biogas, and now in-conduit hydro
