BOULDER CANYON PUMPED STORAGE PROJECT Sam Mannan Project Manager Los Angeles Dept. of Water and Power (LADWP) Agenda Background Why Energy Storage? Duck Curve and Renewables LADWP’s Experience in Pumped Hydro - CASTAIC LADWP and Hoover The “Boulder Canyon Pumped Storage” Project Ongoing Assessments Key Challenges Conceptual Timeline 2 LADWP Overview • Largest municipal utility in the USA • 1.5 Million power customers & 680,00 water customers • Owns more than 25% of state’s transmission lines • Reached 20% renewables in 2010; well-positioned to meet state-mandated level of 33% by 2020 3 Utility Description • LADWP is a vertically integrated utility: – LADWP owns and operates its own generation, transmission, and distribution system – Glendale and Burbank are within LADWP’s Balancing Authority Area 4 State Mandates Regulation Description SB100 - Achieve the 50% by December 31, 2026 - Achieve a 60% target by December 31, 2030 - Policy that eligible renewable energy and zero-carbon resources supply 100% by December 31, 2045. Once Through Cooling (OTC) - Assess the extent to which scheduled OTC units are vital to maintain system reliability and resource adequacy - Determine viable alternative solutions to repower OTC units without sacrificing system reliability, and perform cost-benefit analysis for each alternative SB1339 - Requires publicly owned utilities to develop a standard interconnection process and tariffs, as necessary, within 180 days of a request from a customer or developer - Microgrids may include energy storage, forecasting, demand response, etc. Any resource that meets California Air Resource Board (CARB) standards AB2514 - Requires LADWP to set its ESS procurement targets if it is viable and cost effective - First target date - December 31, 2016 - Second target date - December 31, 2021 SB32 - CARB shall ensure that the Statewide Green House Gas (GHG) emissions are reduced to at least 40% below 1990 levels by 2030 5 Background • Clean energy policy goals along with legislative efforts to decarbonize power resource supplies are generating significant amounts of excess solar and wind energy for utilities throughout the Southwest • While LADWP has deployed batteries as one of several energy storage options, hydro-based Pumped Storage is a proven technology that can be cost effective and potentially less environmentally impactful • To date, LADWP has installed 22.6 MW of new energy storage and is currently evaluating a wide range of energy storage options including pumped storage 6 Energy Storage Technologies Types of Energy Storage Lithium Polymer Batteries Lithium Ion Batteries #1 Chemical Sodium Sulfide Batteries Flow Batteries Chillers, Ice #2 Thermal Hot Water Heaters Pumped Storage #3 Gravity Train Rail Flywheels #4 Mechanical-Kinetic Compressed Air 7 ‘Duck Curve’ Ramping Challenge 8 Renewable Curtailment in California Note: LADWP is not having this challenge today. 9 Castaic Power Plant – 1250 MW - Castaic is sited on west branch of California State Aqueduct - The Project is a cooperative venture between LADWP and the California Department of Water Resources (DWR) - Castaic follows LADWP system load and provides for spinning reserve requirements 10 Castaic Pumped Storage Plant Pyramid Lake - Upper reservoir 30 ft. diameter power tunnel 7.3 miles long One 55 MW Pelton unit for pump starting and load following Six 271 MW reversible pump-turbines Elderberry Lake - Tailbay Castaic Lake - Storage reservoir 11 LADWP and Hoover • Since 1937, LADWP is an original participation of the Hoover Dam. LADWP also operated the plant. • Currently LADWP is committed to participate through 2067. • Hoover is accounted for both electric “generation and capacity” in LADWP’s energy portfolio. • LADWP, together with the other Hoover Contractors, continues to participate in the Lower Colorado River Multi-Species Conservation Program. • Hoover provides base load, carbon neutral, hydro electric energy at a very competitive rate. 12 Hoover Hydro Electric Power Plant 13 14 15 Boulder Canyon Pumped Storage CONCEPTUAL 16 Boulder Canyon Pumped Storage CONCEPTUAL 17 Proposed Routes 18 Proposed Routes 19 Recap - Meetings Held to Date Bureau of Reclamation – Lower Colorado • Dr. Terry Fulp, Regional Director • Jacklynn Gould, Deputy Regional Director • Len Schilling, Area Manager • Theresa Saumier, Manager, Facilities Services • Daniel Bunk, Boulder Canyon Operations Office (Water Operations) • Marc Maynard, Resource Management Office (Land and Environmental) • Mike Bernardo, Region Director Special Assistant National Park Service • Lizette Richardson, Superintendent • Mike Boyles, Lands, Planning, and Compliance Specialist 20 Arizona Power Authority U.S. Dept. of the Interior • Ed Gerak, Exec.
