Failed to unbundle transmission and distribution (2003) for a few reasons
- Opposition from power companies
- Lack of political leadership
- Critiques for the California electricity crisis
4) Adequate & stable supply and few demand response policies

Among other things, smart grid and smart meter technology can be used to:
1) Allow customers to have dynamic (time-varying) pricing
2) Allow customers to access real-time price and usage information
3) Make the most use of EV and plug-in hybrid vehicles as “storage”

Most customers do NOT pay “time-varying” electricity prices16
economic growth throughout the western United States shifted the supply/demandbalance and caused the market to tighten up suddenly. Although the investor-owned utilities had by 2000 received permission to buy a limited amount of powerunder long-term contracts, they were doing very little of it. They were still procur-ing about 90 percent of their “net short” position—the power that they were notproducing with their own generation and did not have under contracts thatpredated the restructuring—in the Power Exchange’s day-ahead or the systemoperator’s real-time market.
In addition, cost increases for thermal generating plants (in California, nearlyall of which are natural-gas fueled) raised production costs and, importantly, did somuch more for the marginal production units. Figure 3 shows the marginal costcurve from all thermal plant capacity in California. This omits production fromnuclear and hydroelectric production, which are inframarginal in nearly all hours,and renewable sources (wind, solar and geothermal), which have less reliableproduction patterns. Thermal plant production is nearly always the marginal powersource in California.
The lowest line is the marginal cost curve during July 1998, when gas priceswere low and the costs of pollution permits for emitting nitrogen oxide werenegligible. The next highest line shows costs during June 2000, when natural gasprices were almost double their 1998 levels. Not only has the curve shifted up, it hasrotated, with the costs of the most expensive units increasing more, because themost expensive units convert natural gas to electricity at about half the efficiencyrate of the least expensive generators. By August 2000, shown in the highest line,the problem was further exacerbated as the price of nitrogen oxide pollution
