TEP BlastTEP Issues Request for Proposals to Build New, Large Solar and Wind Systems

TUCSON, Ariz. | November 4, 2016--(BUSINESS WIRE)

Tucson Electric Power (TEP) is seeking bids for the design and construction of large new renewable energy resources, including a community-scale solar array that could power more than 21,000 homes.

Arizona Utility Eyes Burning Thinning Debris to Protect Water Supply
Arizona Utility Eyes Burning Thinning Debris to Protect Water Supply

By Associated Press | | October 29, 2016


PHOENIX — An Arizona water and power utility is conducting an experiment to add forest-thinning debris to coal burned by an electricity-generating plant, hoping to make thinning more economical to help avoid devastating wildfires producing runoff that would contaminate reservoirs.

A test conducted Wednesday at the Salt River Project’s Coronado Generating Station near St. Johns in eastern Arizona showed that the plant’s machinery can handle mixing woody biomass material with coal, SRP officials said.

That sets the stage for stage for two 10-day periods of burning biomass in November, said SRP water strategy analyst Ron Klawitter.

APS Begins Participation in Flexible, Regional Market to Save Customers Money
APS Begins Participation in Flexible, Regional Market to Save Customers Money
energy imbalance market enables aps to operate more efficiently, better integrate renewables

powersharePHOENIX | – On Oct. 1, three energy traders from Arizona Public Service Co. sat in front of 24 computer screens and successfully completed their first transaction as a participant in the western regional Energy Imbalance Market (EIM). While doing business with other utilities isn’t new for APS, the EIM enables the company to buy and sell power in increments as small as five minutes, garnering efficiencies that are not possible with traditional hour-ahead trading practices. APS expects this difference in trading efficiency could result in savings between $7 million and $18 million a year for customers.

APS Reaches Major Solar Milestone: Tops Gigawatt of Solar Energy
APS Reaches Major Solar Milestone; Tops Gigawatt of Solar Energy
Diverse Solar Portfolio Benefits All Customers

round-flagstaff-solarPHOENIX – This summer, APS surpassed one gigawatt of solar energy capacity, becoming the only utility outside of California to achieve this milestone. When generating at full power, this capacity meets the partial daytime needs of 250,000 Arizona homes. The company’s total investment in solar energy is approximately $2 billion.
APS’s solar portfolio is almost an even split between rooftop systems and grid-scale projects, with 551 megawatts coming from rooftop systems and 499 megawatts coming from grid-scale projects.
“APS customers benefit from the fact that when you include energy from APS’s other renewable energy sources — wind, geothermal, biomass and biogas – and the Palo Verde Nuclear Generating Station, nearly half of all the power on APS’s system is carbon-free,” said Tammy McLeod, APS Vice President of Resource Management. “A cleaner energy mix is a top priority for us, with solar playing an important role.”

SRP's Northern Arizona Coal Plant One of the Biggest Carbon Emitters in the Country
SRP's Northern Arizona Coal Plant One of the Biggest Carbon Emitters in the Country

nav2An electric train delivers 240 cars of coal to the Navajo Generating Station each day, dumping the black fuel into a pile roughly twice the size of the Walmart shopping center in nearby Page.

Each day the plant burns 24,000 tons of that coal, and in doing so, creates nearly double that amount of carbon dioxide pollution, making it the third-largest contributor to greenhouse gas emissions in the country.

Over the years, upgrades have reduced the amount of other pollutants released by the plant's three generators. But the only way to reduce carbon emissions, which gain atomic mass on release, is to reduce how often the plant runs.

srpgasplantSalt River Project's elected board of directors approved spending $100 million to purchase a power block at the Gila River Power Station natural-gas-fired plant near Gila Bend.

The purchase was approved at a Sept. 12 board meeting.

The plant is owned by Entegra Power of Tampa, which sold another unit at Gila River to Tucson Electric Power last year. The plant was built by different companies in the early 2000s to be used as a merchant plant selling power on the wholesale market.

Apple's Secret Solar Plant in Arizona Could Power 12,500 Homes
Apple's Secret Solar Plant in Arizona Could Power 12,500 Homes

applesolarApple Inc. has built a 300-acre solar power plant in Florence to make up for the electricity used in its Mesa data center, and Salt River Project finally released details of the secretive project Tuesday.

Apple wants its customers to know that when they ask the Siri app on their phones for directions, they aren't contributing to global climate change. The company has a goal of generating enough clean energy from multiple facilities to compensate for the power its global factories and other operations draw from the power grid.

Apple said in 2015 when it announced its command center project in Mesa that it would run the facility with solar power, but until now, the Cupertino, Calif.-based iPhone maker hasn't provided any details of how it would accomplish that.
