  1. Managing Risk in the Gridwith Energy Storage Abbas Akhil Principal, Renewable Energy Ventures, LLC (505) 280-0997 abbas@revtx.com 9th Meeting NM Renewable Energy Storage Working Group November 12, 2014

  2. My Background • PNM, Resource Analysis Group: late 1970’s; 13 years • Alternate renewable energy assessments • Reeves solar hybrid repowering study and conceptual design • Sandia National Laboratories, Energy Storage Program: till December 2011. • Energy storage and micro-grids • Lead author of DOE Electricity Storage Handbook, 2013 • www.sandia.gov/ess/publications/SAND2013-5131.pdf

  3. The Electric Grid • Instantaneously match generation to load • Maintain constant voltage and frequency • Plan for load growth – capacity additions and T&G upgrades

  4. Types of Risk • Operational risk • Sudden failure of generating unit or loss of transmission pathway • Sudden changes in renewable energy resources • Intra-hour load management • Planning risk • Unexpected changes in load growth projections – system and distribution level • Distribution and substation upgrades • Time-of-use or demand charge management – customer level • UPS functions – customer level
