Attached is a memo comparing the CEC's forecasted supply and a more realistic
look at what additional resources might be available this summer.

The bottom line is that:

1. The CEC significantly underestimates the outages that may occur this
summer. They estimate in their 5,000 MW supply deficit for the summer that
expected outages will be around 3,000MW. However, November and December saw
significantly higher outage levels. (7,265 MWs) The FERC has investigated
these outages and found no improprieties- just that the plants are overtaxed
from running at higher than normal capacities.

2. There are a lot of uncertainties surrounding the 1,244 MWs of projected
supply from rerating/restarting existing thermal and renewable projects. It
is very unclear how much of this will be able to come on line by this summer,
if at all. As evidenced by the e-mail I sent out this morning, local
communities may be very opposed to restarting shut down units. In addition,
these units are likely to be uneconomical.

3. In the existing resource pool, there are roughly 1,430 MWs of peaking or
other generation units that are running up against their operating hour
limitations from air quality regulations. The Governor has ordered the local
air quality districts to address these restrictions, We are beginning to
seem some movement; however, the US EPA has yet to weigh in on these relaxed
standards.

4. The distributed generation/back-up generation capacity to make up some of
the shortfall is still an unknown. While there has been some relaxing of the
limitations on run hours for back-up generation at "essential public
services" the increase in DG is expected from "clean" sources, not diesel
emergency generators.

5. The CEC is doing everything it can to get 50+ MW peaking units on-line by
this summer. They are promising a 21-day permit application approval process
and are offering to pay half of the cost of offsets, for "clean" sources of
generation in critical areas.

Please let me know if you have any questions or need additional information.
