Tucson Electric Turning to Renewable Energy (Ind. Report)
Tucson Electric Power
Date: 2021-05-03
In Arizona, Tucson Electric Power Co. reports it plans to "flip the switch" on its 100-MW Wilmot Solar Energy Center which was built and owned by NextEra Energy. The facility includes 30MW of linked battery storage.

The utility's largest renewable energy resource, the 250MW Oso Grande Wind Project in New Mexico is also expected to come online soon. With both the Wilmot solar and Oso Grande wind projects online, TEP will have 628 MW of large-scale wind and solar resources.

TEP aims to generate 70 pct of its power from renewables and cut its carbon emissions by 80 pct by 2035. The Arizona Corporation Commission is aiming for state-regulated utilities to source 100 pct of their energy from carbon-free sources by 2050.

Rooftop Solar Rejected to Avoid Solar Saturation (Ind. Report)
Tucson Electric Power
Date: 2020-08-17
Tucson Electric Power (TEP) is reported to have rejected several new residential rooftop solar installation applications under new Arizona Corporation Commission rules governing the maximum solar generation capacity on any one neighborhood circuit.

The rule is designed to prevent "solar saturation" and protect the system from damage due to an excessive amount of power being exported back onto the power grid.

The neighborhood solar capacity rule has led to the rejection of applications in 11 areas of Tucson that already have reached solar "solar saturation", according to TEP. (Source: TEP, Tuscon,com, Aug., 2020) Contact: TEP, Joseph Barrios , (520) 884-3725, jbarrios@tep.com, www.tep.com

TEP Touts Clean Energy Expansion Plan (Ind. Report)
Tucson Electric Power
Date: 2020-06-29
Tucson Electric Power (TEP) is reporting plans to provide more than 70 pct of its power from wind and solar resources as part of a cleaner energy portfolio that will reduce carbon emissions 80 pct by 2035.

The 15-year 2020 Integrated Resource Plan (IRP) calls for a dramatic expansion of wind and solar power resources, supported by efficient natural gas fired generators and energy storage systems the retirement of TEP's remaining coal-fired power plants over the next 12 years. Key IRP elements include:

  • 2,457 MW of new wind and solar power systems, including 457 MW that will be coming online over the next year.

  • 1,400 MW of new energy storage systems.

  • A proposal to ramp down and ultimately retire two units at the coal fired Springerville Generating Station in 2027 and 2032.

  • Eliminating the use of surface water for power generation and a 70 pc treduction in groundwater use.

  • Continued support for energy efficiency programs to reduce usage and peak power demands.

    TEP's CO2 emission reduction goal was developed in partnership with the University of Arizona's Institute of the Environment with input from a diverse group of customers, community leaders, local government representatives and environmental advocates. The target represents TEP's fair share of worldwide efforts to limit global warming to well below 2 degrees Celsius under the 2015 Paris Agreement. TEP's plan would reduce its CO2 emissions by 80 pct, according to the release.

    Green Valley News Comments on Arizona Energy Efficiency Standard (Opinions, Editorials & Asides)
    Energy Efficiency
    Date: 2019-05-13
    With the approaching demise of Arizona's Energy Efficiency Standard, the Arizona Corporation Commission should note that from 2010-17, every $1 of ratepayer money invested in energy efficiency by Arizona Public Service and Tucson Electric Power returned about $4 in benefits to ratepayers. The Standard also helped reduce water consumption and contributed to job creation.

    The standard set aspirational yet rational requirements incorporating annual benchmarks and establishing accountability measures such as implementation plans. As the Commission deliberates its next steps on energy efficiency, here are a few considerations commissioners should keep in mind:

  • A strong standard will accomplish more than a goal. In large part, the reason Arizona's Energy Efficiency Standard has worked is due to requirements the Commission placed on utilities. Without a Standard, it is unlikely Arizona's utilities would have significantly increased the use of energy efficiency resources.

  • Arizonans support energy efficiency. According to an energy poll released earlier this year, 68 pct of those polled agree that regulations applied to utility providers, such as Arizona Public Service, Tucson Electric Power, UNS Energy Corporation, or Salt River Project should be increased to ensure they are offering energy efficiency to all their customers.

  • The recent trend among state policy makers and utilities in the Southwest is a shift to increased energy efficiency commitments. Just like it is realistic and no longer visionary to send a man (or a woman) to the moon; it is realistic and no longer visionary to increase Arizona's Energy Efficiency Standard.

    For the sake of ratepayers, air quality and public health, the Commission should vote on May 22 to advance Arizona’s Energy Efficiency Standard to at least 35 pct by 2030. (Source: Green Valley News, 12 May, 2019) Contact: Arizona Corporation Commission, (602) 542-3026, www.azcc.gov

  • CCS Proposed for Soon to be Shuttered Coal Plant (Ind. Report)
    Acme Equities LLC
    Date: 2019-03-04
    Acme Equities LLC , a private NY based real estate investment company that focuses on North American energy projects, reports it is aiming to take over the 847-MW New Mexico's San Juan Generating Station (SJGS) and refit the 46-year-old, coal-fired plant with carbon capture and sequestration (CCS) technology.

    The plant is presently slated for shutdown in 2022. The addition of CCS technology would cut carbon emissions by an estimated 90 pct and offer the plant another revenue stream with the sale of the captured CO2 for enhanced oil recovery well production.

    Acme Equities has reached an agreement with the city Farmington N.M., part-owner of the plant, to keep the SJGS open beyond 2022. Other owners of the facity include Tucson Electric Power, Los Alamos County, and Utah Associated Municipal Power Systems, along with majority owner Public Service Company of New Mexico (PNM), all of which have said they do not plan to receive power from the SJGS after 2022.

    Arizona Utilities Encouraged to Increase Energy Efficiency Investments (Ind. Report)
    US PIRG, Tucson Electric Power
    Date: 2018-12-12
    With just days before the Arizona Corporation Commission is expected to vote on Tucson Electric Power's (TEP) Demand-Side Management Plan, Tucson business owners are encouraging the Commission to increase investment in energy efficiency. The Arizona PIRG Education Fund and the Southwest Energy Efficiency Project, who have been speaking with business owners across Tucson, are hopeful the Commission will restore and increase energy efficiency funding for TEP ratepayers.

    In a letter to the Commission, three dozen business owners cited the return on investment, the creation of local jobs and reduced energy waste attributed to energy efficiency. According to the letter, since 2010, energy saving programs implemented by TEP and Arizona Public Service Company (APS) deliver approximately $3.90 in benefits for every $1 invested by ratepayers. Additionally, the APs and TEP energy-saving programs have cut energy waste by delivering demand savings greater than eight 100MW peaker power plants.

    TEP Warns AZ Clean-Energy Policy Doable but Costly (Ind. Report)
    Tucson Electric Power,Arizona Corporation Commission
    Date: 2018-07-16
    In Arizona, Tucson Electric Power Co. (TEP) is warning that although the state "energy modernization" plan requiring utilities to generate 80 pct of their power from renewable sources by 2050 is doable, it could raise costs for the company and its ratepayers by more than $800 million through 2030, and cause the eventual closure of TEP-owned power generation stations. The higher costs would mainly include an additional $673 million in investments in energy-storage systems and about $53 million for new biomass energy projects.

    The Arizona Corporation Commission plan aims to encourage the development of renewable generating plants with energy storage. It would also count energy from Arizona Public Service's Palo Verde Nuclear Generating Station as clean energy.

    TEP says it generally backs the objectives of energy modernization plans and favors coordinated, integrated resource energy policies overseen by elected officials. The utility also notes it is already pursuing clean energy goals that exceed existing state requirements. The utility has 21 megawatts of battery energy storage currently operating, and has contracted for 30 MW of four-hour battery storage as part of a 100 MW solar farm slated to reach commercial operation in late 2020. TEP says it is also considering purchasing or contracting for up to 200 MW of the proposed Big Chino Valley pumped-storage hydro project north of Prescott, which is expected to be online in 2025.
