The plan is part the utility's SRP 2035 long term growth plan, as laid out at the close of its 2018 fiscal year.
By 2025, SRP anticipates 11 pct of its energy needs will be met by solar and avoid another 11 pct of its current supply level from energy-efficiency measures. The utility's energy storage plan includes the purchase of a 25 MW/100 MW-hour battery storage system from Tesla, to be installed at the Agua Fria Generating Station in Glendale, California.
SRP notes that it paid over $150 million in solar incentives to approximately 20,000 customers between August 2004 and April 2018, and $205 million since May 2008 in energy efficiency incentives resulting in an overall 2.14 pct annual incremental energy savings exceeding the 2 pct annual target.

The two ASU teams are headed by Wim Vermaas, Foundation Professor in the School of Life Sciences and a member of the Center for Bioenergy and Photosynthesis, and Bruce Rittmann, director of Biodesign Swette Center for Environmental Biotechnology.
Both ASU projects are developing innovative approaches for improving the efficiency of microalgae to capture waste CO2 and convert it into biodiesel transportation fuels and other valuable products.
Rittmann will explore ways to make CO2 delivery to algae more efficient. Traditional methods involve sparging (bubbling) CO2 within the liquid used to grow the algae, which releases about 60-80 pct of the CO2 back into the atmosphere. This wasteful process defeats a major goal of using microalgae to remove this greenhouse gas from the atmosphere and decreases cost efficiency.
Rittmann's team developed a membrane carbonation process that uses inexpensive plastic fibers to deliver pure CO2 with nearly 100 pct efficiency directly to the microalgae. The team estimates that the technology will capture fourfold more CO2 than traditional sparging methods.
The team is partnering with the Salt River Project to develop methods for harvesting CO2 from power plant emissions. They are also partnering with the city of Mesa to remove CO2 from the biogas generated from anaerobic digesters at their wastewater treatment facilities. Rittmann's team will investigate whether the fibers can be used with microalgae to remove CO2 from the biogas, which would leave nearly pure methane which could be distributed through existing natural gas pipelines.
Vermaas and his team were awarded $2.5 million to pursue an innovative multi-pronged approach toward improved CO2 utilization.
One approach is to increase the solubility of carbon dioxide in growth medium by developing a nanobubble gas delivery system.. A second approach is to utilize amines in the medium, which greatly enhance the solubility of CO2, allowing the gas to be taken up by photosynthetic microbes for producing biofuel.
The researchers anticipate at least a 50 pct increase in the efficiency of CO2 use with advanced biofuel production under industrially relevant conditions.
