What’s Up with City of Tucson Solar??
Bruce Plenk, City of Tucson Solar Energy Coordinator Office of Conservation and Sustainable Development
The City is Building Solar!!
• In 2011 and 2012, the City of Tucson built
over 2 MW of PV at police substations, the
TCC, the Price Service Center, and the
Randolph Rec Center gym.
• These systems included rooftop and
carport designs designed to save energy
and police car electronics!
• Financed with CREBs bonds

The City is Buying Solar Power to
meet City needs
• Did you know the City spends over $15
million each year on TEP bills alone?
• TEP has asked for a 15% rate increase
• Locking in power costs with solar PPA’s
makes sense!
• Moving water is our biggest single energy
expense

Tucson Water CAVSARP Pumping
Station-I MW PPA (possible
expansion?)
The City is leasing unused City
land for wholesale solar projects
• This supports TEP’s plan to locate utility-
scale PV projects close to end use
locations
• Can tie into local distribution lines and
avoid long distance transmission lines
(and dangers from forest fires!!)
• Provides income to City

The Big Dogs: FRV (Sun Edison) and NRG
(First Solar) Solar Farms in Avra Valley-
Each 25 MW! Now being completed
The City is providing better
information on solar
• Puzzled about solar?
• Overwhelmed with geeky terminology?
-grid-tied
-kWh
-PPA/lease
-changing utility incentives
-state and federal tax credits

• Energy = Water
Learn about energy in our
Tucson water-solar saves 2x!
4,800 kwh of electricity to pump
1 acre foot of water to our homes
Typical Tucson home with four people will use .51 acre
feet/year
4,800 kwh/acre foot x .51 acre feet = 2,472 kwh/year
Water is the fourth largest user of
Electricity in the home after water
heating! Slide courtesy of Rich Franz-Under,

The City is trying out solar in other
applications
• Streetlights
• Pedestrian crossings, etc
• New solar hot water systems
• What’s next?

Solar Streetlights-Barrio Centro
The City is changing policies to
make solar easier • Land Use Code changing to make solar
possible in all zoning categories and looking at more changes
• Simplified solar permit procedures in all Pima County jurisdictions
• Net zero building program relies on solar!
• Solar Benefits Tucson-group buy makes solar cheaper
• Solar building permit fees waived
• New codes push energy efficiency

Plaza del Sol PV-630 kW, single axis
trackers. Possible due to zoning changes
Plaza del Sol-600 kW
Net Zero Homes and Buildings
New codes focus on energy
efficiency, solar’s #1 partner!
• Buildings after 1/1/13 will need to be 30%
more efficient than they are now, so a
smaller PV system could provide power!

Southline Transmission Project
• Similar route as SunZia
• More favorable environmentally
• Uses more existing lines and upgrading;
less intrusion on undeveloped areas
• Similar intent: get electricity from NM wind
farms to Arizona (SunZia goes on to CA)
