Who is SRP?


SRP Electric Facts

An integrated electric utility, providing generation, transmission and distribution services

Generating mix includes fossil fuels (coal and natural gas), nuclear and renewable energy resources

Renewable energy resources includes solar, wind, landfill gas, biomass, geothermal and hydroelectric generation

2,900 square mile electric service area, spanning three counties


SRP’s Resource Mix

Coal47%

Natural Gas32%

Nuclear15%

Renewables6%


SRP Water Facts

SRP administers water rights to a 250,000-acre area that spans 375 square miles

SRP has more than 2.3 million acre-feet of water storage capacity

SRP provides about 850,000 acre-feet of water each year to municipal, industrial, agricultural and residential users

Extensive water delivery network includes 133 miles of main canals, 1,132 miles of laterals & ditches and 255 large capacity wells


Environmental Challenges Facing SRP

Arizona is a high growth state and will require more electric generating resources with varying environmental impacts

Climate change is the most significant environmental challenge facing us today

Potential greenhouse gas regulations could seriously impact our generation options

Compliance with environmental / greenhouse gas regulations may have a significant cost impact to our customer rates

Arizona is a dry desert climate and water supply issues are critical for the future of our state


SRP is Addressing These Challenges

Water treatment0.7%

Water distribution

4.6%

Over 80% of the electricity use and carbon emissions

for the entire residential (potable) water use cycle

can be attributed to water heating in the home

Electricity Embedded in the Water Use Cycle


Monthly water use of ~10,000 gallons translates to:

− About 300 kWh embedded electricity

− About 430 pounds of CO2

300 kWh is the equivalent of leaving four 100-watt light bulbs burning non-stop all month long!

What this Means…for a Home


Paradigm Shift

This is a water-saving device!

This is an energy-saving device!


DesertWise Living

About 30% of total water use occurs inside the home

Toilets are the biggest water user (nearly 30%)

− Switch to high-efficiency toilets that use 1.3 gallons per flush

− Saves about 15,000 to 20,000 gallons per year for a family of four

Water- and energy-efficiency front-loading clothes washers use 35-50% less water and about 50% less energy than conventional models

Fixing leaky faucets can save 140 gallons of water per week

Replace shower heads with low-flow shower heads to likely save about three gallons for every minute you shower

Look for EPA’s WaterSense labels when purchasing new sink fixtures as these fixtures reduce a sink’s water flow by 30% or more without sacrificing performance


DesertWise Landscaping

About 70% of total water use occurs outside the home

Consider desert landscaping and plants that use less water

Install a smart irrigation controller which save about 25% of the water used outdoors by automatically linking the watering schedule to actual weather conditions or moisture at the root level

Use a liquid pool cover or install a pool cover to reduce evaporation

Use rain gutters to channel rainwater toward the landscape


You Can Take Action


Cooling is the Key

Heating / cooling is about half the average annual residential bill

It is the most variable part of the bill

It gives us the most potential for savings


Efficient Air Conditioning

How much can high efficiency air conditioning save?

New electric heat pumps and air conditioning units are about 40 to 50% more efficient than units installed 15 years ago

Replacing a 7 SEER unit with a 16 SEER unit can reduce the cooling portion of your electric bill up to 50%


Duct Test and Repair

Why is it important?

On average, 15% of cooling is leaked through ducts


You Can Take Action

Buy energy efficient appliances with EPA Energy Star ratings

Use low-energy compact fluorescent light bulbs (CFLs)

Caulk and weather strip all windows and doors, and insulate your walls and attics to make your home more energy efficient

Plant shade trees or use screens to shade windows on the outside of your home, and keep drapes and shutters closed during hot summer days

Install low-flow showerheads, desert landscaping and low-water use plants to reduce your water usage


Carpool or take public transit to save gas and reduce auto emissions

Consider the purchase of a hybrid, or low fuel use vehicle

Use recycled paper to conserve our forest resources

Inflate your car tires properly – it gives you higher gas mileage

Pay bills online and save paper, postage and transit costs

Shut off your computer and other appliances when not in use to save electricity

You Can Take Action


SRP and the utility industry, face many challenges related to growth, climate change and balancing costs for our customers as we strive to provide a sustainable energy supply

SRP has a long and rich history of contributing to the development of the greater Phoenix area through careful management of precious natural resources

Providing a sustainable energy source for the Valley is critical

SRP is committed to incorporating renewables, energy efficiency and water efficiency into our resource mix at the lowest cost to our customers
