Meeting Utility Resource Needs with Solar

  1. 1. Meeting Utility Resource Needs with Solar: The Merits of the Aurora Solar Project Nathan Franzen | Geronimo Energy, Director of Solar Lindsey Hemly | Fredrikson & Byron, Legal Counsel March 19, 2014
  2. 2. Pg. 2
  3. 3. Pg. 3
  4. 4. Pg. 4 The Impact of Window Energy Efficiency and How to Make Smart Choices Thursday, April 10th 11:00 – 12:00 CST Window retrofit technologies applicable in Minnesota’s two climate zones as a way for building owners to save money. Target Audience •Building managers and facility professionals •Utility commercial program managers •Commercial and residential building envelope contractors •Window and window film manufacturers/installers •Building scientists and design professionals Gustav Brandstrom Project Engineer, CEE
  5. 5. Pg. 5 Presenters & Overview Nathan Franzen Director of Solar Lindsey Hemly Legal counsel Presentation Outline •Geronimo background •Overview of project site, capacity, and innovations •Benefits of this project over other resource options •Replicability of project model
  6. 6. Geronimo Energy • 4th largest wind energy developer in the U.S.A. • Headquartered in Minneapolis, MN • Decades of expertise, on-the- ground experience • Over 1,300 MW set for construction 2014-2016 • Ground-mount, rooftop, utility and commercial scale solar offerings • Geronimo has a strategic partnership with Enel Green Power 6March 19, 2014 www.geronimoenergy.com
  7. 7. Project Specifications •Operational Capacity: 100 MW •Location: 16 Minnesota counties •Construction Timeline: 2015 - 2016, or 4-9 months for each site •Number of Sites: ~25 (primary and alternate) •Project Cost: ~$250 million •Local Tax Revenue: up to $240,000 annually* •Expected COD: December 1, 2016 7March 19, 2014 www.geronimoenergy.com
  8. 8. Project Details •100 megawatt (MW) AC distributed solar resource •Utilizes solar arrays from 2 - 10 MW across Xcel’s service territory •Interconnects to multiple Xcel Energy distributed substations in MN •Provides energy and MISO accredited capacity to Xcel and its customers • The Aurora Solar Project will provide a cost effective alternative to thermal generation. 8March 19, 2014 www.geronimoenergy.com
  9. 9. Unique design delivers many benefits: •71% MISO accredited capacity –Helps utilities meet reliability requirements –100 MW AC = 71 MW of accredited capacity •Distribution delivery = Reduction in line loss (4-5%) •Elimination of transmission costs –Increases overall grid capacity 9March 19, 2014 www.geronimoenergy.com
  10. 10. Unique design delivers many benefits: •Geographic diversification of generation assets –No point source failure (think polar vortex) •Cost –Fixed price, no fuel cost uncertainty •Meets solar standards 10March 19, 2014 www.geronimoenergy.com
  11. 11. How Did We Get Here? • PUC found that Xcel had a need of up to 500 MW by 2019 • Need was defined as “peaking or intermediate” capacity • Xcel wanted to propose its own resources to fill the need • With Xcel participation, the PUC evaluates and selects the best resource(s) 11March 19, 2014 www.geronimoenergy.com
  12. 12. What Was Proposed? Xcel: 3 208 MW Combustion Turbines (CTs) Invenergy: 3 160 MW CTs Calpine: 345 MW expansion of Mankato Combined Cycle (CC) GRE: 200 MW short term capacity credits Geronimo: Aurora SolarMarch 19, 2014 www.geronimoenergy.com 12
  13. 13. ALJ Lipman’s Recommendation: • Xcel’s actual need is uncertain • Aurora is most economical option – Least cost option based on Strategist modeling – Lowest Levelized Cost of Energy (LCOE) • Scalability – Solar modular design and short lead time is more suited in a situation where the need is rapidly changing. 13March 19, 2014 www.geronimoenergy.com
  14. 14. ALJ Lipman’s Recommendation: • Renewable Preference Warranted • Gas proposals not fully vetted. – Issues with non-firm gas, unresolved interconnections etc. – Gas bidders did not offer “fixed price” leaving rate payers exposed. • Aurora will help meet numerous state policy goals, including the solar standard • If the PUC finds additional need, choose GRE 14March 19, 2014 www.geronimoenergy.com
  15. 15. ALJ Lipman Determines Aurora Solar Is Most Economical Option "Since 1991, Minnesota has had a statutory preference in favor of renewable energy sources. Yet, that preference is overridden when the nonrenewable source has a lower total cost. Notwithstanding the statutory preference, it seemed that nonrenewable energy sources always won the head-to-head cost comparisons. Not anymore." – ALJ Lipman 15March 19, 2014 www.geronimoenergy.com
  16. 16. Next Steps • Xcel and DOC disagree with ALJ report • Xcel recommends Black Dog + Calpine and Invenergy • PUC can accept, reject or modify ALJ recommendation • Oral Argument 3/25, Deliberations 3/27 March 19, 2014 www.geronimoenergy.com 16
  17. 17. In Summary Competitive Resource Acquisition Process •Pros: – Transparent process – Allows side by side comparison of competing proposals – Eliminates Utility bias towards rate based projects • Con’s – Expensive, but could be improved upon •Next Steps 17March 19, 2014 www.geronimoenergy.com
