A New Solar Power Generation Milestone For The Company.
Earlier this year Pheonix based utility, APS surpassed one gigawatt of solar energy capacity. This is the first electric utility company outside of California to achieve this milestone. This $ 2 billion investment has the capacity to meet the partial daytime needs of 250,000 Arizona homes.
Arizona has such terrific solar resources available. Tapping this renewable treasure trove of energy would spur economic development and create thousands of good jons for residents of the state.
Rooftop Versus Utility Scale Solar Capacity.
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.
Tammy McLeod, APS Vice President of Resource Management commented on the milestone:
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. A cleaner energy mix is a top priority for us, with solar playing an important role.
APS receives its grid-scale solar generation from a combination of APS-owned systems and power purchase agreements. Through its AZ Sun Program, APS owns and operates nine solar plants across Arizona. These plants were designed and constructed by independent solar developers, contractors and equipment providers, and provide 170 megawatts of capacity. The rest of APS’s grid-scale solar comes from independently owned power plants across Arizona with long-term agreements to sell power to APS.
Most of the power from rooftop solar comes from systems owned by homeowners or leasing companies. APS owns ten megawatts. The APS-owned systems are strategically placed on customer homes in a way that allows the company to engage in research and development activities on how solar and other advanced technologies, such as smart inverters and battery storage, impact the ability of the utility to provide reliable and safe energy for customers.
