NEI Energy Markets Report (July 31st - August 4th)

Here's a summary of what went on in the energy markets last week:

Electricity prices increased in all parts of the country except for the West. Prices spiked over $200/MWh at the PJM West hub (see pages 1 & 2). Gas prices at the Henry Hub rose $1.45 to $7.97/MMBtu (see page 4).

Nuclear capacity availability was at 97 percent last week. Three units (Fermi 2, D.C. Cook 1 and Watts Bar 1) were each down several days (see pages 2 & 3).

From 2006-2010, the current capacities in the pipeline coming into operation are 44,681 MW for natural gas, 42,402 MW for coal, and 20,049 MW for wind (see page 8).

What is the 3% difference between electrical demand (3,881.60 BkWh on page 8) and output (4,012,641 on page 5)?

The demand is flat from 2005 to 2006, and the output rose 2.7% !?

It appears that a large amount of planned wind generation shifted from 06 to 07. Any info on that?

The first difference is the transmission losses. Output is the generation from the plants and demand is the actual consumption.

The second difference are the sources. EEI (page 5) publishes actual weekly data whereas EIA (page 8) publishes projected data even for months which have already passed.

For the historical data I would look at EEI and not EIA. The purpose of EIA data for this report is to mainly show the projections of prices and demand.

What kind of info are you looking for from the wind shift?

Email me directly if you have further questions.
