California's power crisis has implications for power markets world wide, be
cause of the severity and unpredictability of its impacts. Ais paper discus
ses the causes of the crisis and derives lessons for energy policy makers.
The crisis was triggered by a fundamental imbalance between the growing dem
and for power and stagnant power supply. California's market design greatly
magnified the problem, by disconnecting the retail and wholesale markets f
or electricity, and by requiring the investor-owned utilities to buy their
power on a spot market. Low hydro conditions, hot weather, and rising natur
al gas prices put the market over the edge. A major lesson that has been le
arned is to introduce demand elasticity in restructured market designs, and
permit buyers of power to hedge against price volatility by engaging in fo
rward contracts.
