U.S. ELECTRIC GRID IS NOT SMART. IT WAS NOT planned and constructed to be able to meet the new constraints, variables, and uncertainties that the future holds. The central system architecture and operating schemes have not really changed in a century.
Long-term construction and operations plans were founded upon the availability of
extra capacity and redundancy to passively withstand short-term variation of
demand, longer term growth, and outages of lines and equipment. The traditional
tools to achieve adequacy and reliability, additions to conventional
generation, transmission, and distribution assets are not as viable
now. Already, electric utility performance indicators are eroding:
economy, reliability, security, asset value, profitability, sustainability,
and service quality. |
