PG&E reports minimal customer conservation overall, 2010-2013; zero savings for web monitoring customers in 2013

“Analysis: Smart Meter and Smart Grid Problems” (p. 116 – 117) showed PG&E’s 2010 and 2011 “SmartMeter™ Program Enabled Energy Conservation Program” charts from their annual reports. Here are now the charts for 2012 and 2013.

PG&E’s numbers are confusing and contradictory from year to year. There are obvious errors, such as “0” under total enrolled customers for 2010. Customers enrolled in two programs are double counted in 2012, as PG&E notes.

The net result is that during these four years, there has been very minimal conservation savings by consumers, less than what could have been achieved without the expense and considerable problems of the Smart Meter program.

The web program, greatly hyped by PG&E and other utilities, and their premiere PR tool, appears to be a failure, especially for 2010 and 2013, as far as energy conservation.

Demand reduction is not happening at all.

This data is compared below with PG&E’s own suggestions from their literature.

These energy figures do not take into account the considerable energy use by Smart Meters, infrastructure, and related data storage facilities.

There are probably other “gems” hidden in these reports.

PG&E’s program has cost the public billions of dollars, with more costs accumulating. Keep that in mind as you look at these figures which contrast sharply with everything PG&E and the energy companies have said.

The financial benefits for 2011 were $94,000 divided by 199,833 enrolled customers. Each customer saved 47 cents for the entire year. The energy savings per customer was .0096 MWh or 9.6 kWh for the entire year.

This is in stark contrast with energy savings promoted by PG&E in a customer booklet.

9.6 kWh Smart Meter conservation benefits per year
versus
300 kWh simple conservation per year –
that’s a big difference.

Below are PG&E’s figures for 2012 and 2013. How do they compare?

[45’ Because we did not account for dual enrollment for CWP and EA, the two energy savings numbers corresponding to these programs when added together will be likely to double count the impacts from these programs.

The financial benefits for 2013 were $917,700 divided by 566,297 enrolled customers. Each customer saved $1.62 for the entire year. The energy savings per customer was .0316 MWh or 31.6 kWh for the entire year.

Even if you exclude the non-saving CWP-enrolled customers, you still get only $14.50 for the entire year, with an energy savings of .283 MWh or 283 kWh

For 566,297 customers:

Adjusted Total
For 63278 customers:

EA, dual, HAN/BAN                 .282 MWh           282 kWh              $14.50

 

This is less than the savings PG&E says can be obtained by very inexpensive means.

Neither of the suggestions above cost the public billions of dollars initially and ongoing millions into the future.

Neither of their suggestions violates privacy or endangers the public.
