• Provides service in 11 of Arizona’s 15 counties.

Energy Efficiency Standard

• Statewide EE Standard approved by the ACC in Dec. 2009. Went into effect in Jan. 2011.

Annual Energy Savings as a % of Retail Sales

Est. cumulative energy savings required by 2020 = 6,500,000 MWh

Achieved to date (2005 to 2010) = 1,091,000 MWh (17% of the way)

Multifamily Energy Efficiency Program

• The Multifamily program is a new program introduced in 2011 and is currently in a launch phase.

• Program debut is expected in April • To qualify the community must be in the APS

service area, be a multifamily facility of at least 5 units, and to receive water saving measures must have electric water heating.

• APS is creating a participation list of interested communities.

Why have an EE Program for Multifamily?

• Large number of APS customers live in multifamily dwellings.

• Large untapped resource for energy savings.

• APS needs significant energy savings to meet new state goals.

Multifamily Program Tracks

• Direct Install for dwellings

• Common Area retrofits

• New Construction and major renovation

Dwelling Direct Install Retrofits

• APS and your property Manager completes a walk through assessment of community.

• APS provides enough FREE CFL bulbs, and energy efficient showerheads and faucet aerators to retrofit each unit in the community

• Communities provide component installation with field support from APS.

• Follow up inspection required to verify installs.

Common Area Retrofits

• APS provides a complementary energy assessment of all common areas and commercial facilities.

• Energy saving opportunities and corresponding APS rebates are identified.

• APS rebates typically cover about 75% of the incremental cost of retrofits.
