My Background
• PNM, Resource Analysis Group: late 1970’s; 13 yearso Alternate renewable energy assessments
o Reeves solar hybrid repowering study and conceptual design
• Sandia National Laboratories, Energy Storage Program: till
December 2011.o Energy storage and micro-grids
o Lead author of DOE Electricity Storage Handbook, 2013
o www.sandia.gov/ess/publications/SAND2013-5131.pdf
The Electric Grid
• Instantaneously match generation to load• Maintain constant voltage and frequency
• Plan for load growth – capacity additions and T&G upgrades
Types of Risk
• Operational risko Sudden failure of generating unit or loss of transmission pathway
o Sudden changes in renewable energy resources
o Intra-hour load management
• Planning risko Unexpected changes in load growth projections – system and
distribution level
o Distribution and substation upgrades
o Time-of-use or demand charge management – customer level
o UPS functions – customer level
