Notes:

•

Rates effective January 1, 2010 include Act 129 Energy Efficiency surcharge of 2%.

•

Act 129 Smart Meter surcharge will be calculated following approval of PECO’s Smart Meter Plan expected in 2Q10.  The Smart Meter surcharge,

which

will

likely

be

effective

3Q10,

is

expected

to

be

less

than

1%

and

is

not

expected

to

increase

until

2Q/3Q

of

2011.

As

a

result,

the

Smart

Meter surcharge will have a minimal impact on rate increases effective January 1, 2011.

•

Low income discounted rates were subsidized in the Power Purchase Agreement in 2010 and will be recovered through distribution rates in 2011.
