Light Commissioner Meeting
The meeting was called to order at 8:55 PM.
Electric Rate Design Presentation by Mayhew Seavey - Director Babin began by reminding
everyone that at the September 18, 2006 Light Commissioners meeting there was a discussion
about the PPCA, how it works and the fact that it had been increased. There was also a
discussion at that meeting about how the underlying rates might be too low and the PPCA was
being used to compensate for that. As a result, Mr. Seavey was asked to partake in this meeting
and make a presentation regarding rates.
Director Babin said that Mayhew Seavey of PLM would present an overview on electric rate
design as well as a discussion of bundled rates, which is what MMED currently uses, versus an
unbundled rate. Director Babin also explained that Mr. Seavey's Power Point presentation
would be shown directly to those at home, as had been suggested by Commissioner Baldwin.

Mr. Seavey spoke about how electricity is a single product but is priced differently to different
groups of customer classes. He explained that the basic objective of rate design is that the rate
needs to be adequate to sufficiently cover expenses and provide net income. The measure for
this is the overall rate of return. Another objective of rate design is that the rate should be fair;
the measure ofthis is the class rate of return. A third objective is that the rate be competitive, the
measure of this is typical bill comparisons. Another objective of rate design is stability, which
can be measured by monthly adjustments. There should also be clarity, the measure of clarity
being that you know what it is when you see it.
Mr. Seavey explained the three basic factors of cost allocation. The first factor is customer cost
allocation, examples of which are metering, billing and customer accounts. The second factor is
demand allocation, examples of which are transformers and lines. The third basic factor is
energy allocation, which is purchased energy and fuel charges.
He then explained that the Historic Test Year Cost of Service Study allocates costs to each
customer class then compares the actual revenues to the expenses to determine the rates of return
for each customer class. The Proforma Test Year Cost of Service Study uses forecast data in
place of historic data and is used to determine the impact of changes in rate design.
Mr. Seavey talked about developing rate designs which produce adequate revenue to cover
operating expenses plus fund capital improvements and the PILOT. The rate design should also
send clear and correct price signals to the customers.
( Policy considerations for the Board were then discussed. The Board must consider which of
three rate objectives that they wish to be achieved by a rate design: the first objective is whether
(
the rate design should produce uniform rates of return by class: the second is whether the rate
design should produce competitive rates for all customer classes; the third objective is whether
the rate design should produce a uniform percentage change for each customer class. Each
objective produces a different rate design which has a different impact on each customer class.
Balancing these three objectives is the policy decision the Board must make in directing staff to
produce a rate design.
Mr. Seavey then discussed developing specific types of rate designs. He stated that MMED
currently has bundled rates. This design includes a customer charge, base energy charge, base
demand charge, where applicable, and the purchased power cost adjustment charge (PPCA).
An unbundled rate design is more detailed than the bundled rate design. There is a customer
charge which covers the costs of metering, billing and customer service. There is a distribution
charge covering depreciation expense, interest expense, administrative and general expense and
distribution operating & maintenance expense. A transmission charge recovers all of the costs
associated with transmission of electricity. The generation charge recovers all of the cost of
purchased power. The last charge is an energy conservation charge to support the costs of
customer programs for load management and conservation.
It was also noted that the distribution charge is the one rate component that recovers any net
income the utility may make and that all other costs are straight pass-thoughs with no profit built
m.

Director Babin stated that there were two major points he wanted to make to the Board. The first
point is that with unbundled rates everything is far more transparent, which makes the rate more
comparable with investor-owned utilities on a line-by-line basis. The second point is that
determining the rate setting mechanism is a Board policy issue. Director Babin wants the Board
to understand that there are different ways of approaching rate design.
The Board could direct that MMED staff along with Mr. Seavey take a look at the rates and that
the Board must determine whether the rate design should produce uniform rates of return,
competitive rates for all customer classes or uniform percentage change for each customer class.
Chairman McCue asked Mr. Seavey if moving to unbundled rates would mean a change in cost
for the customer. Mr. Seavey responded there would be no significant change in cost and
unbundling would also make the rate more understandable.
Commissioner McCarter inquired as to whether it would mean more work each month for the
billing person or whether it would possibly mean another administrative position. Mr. Seavey
answered that it would not impose an additional burden and that creating an unbundled rate is a
one-time job which is completed once the new rates are put into effect.
Vice Chairman Amoruso wondered if the bill was unbundled, would MMED's bill look like
NSTAR's bill. He noted that the format of such a bill would not be in favor of the customer
understanding it and believed it would create more questions. He also wondered if every time a
change was necessary, would MMED have to go to the DTE? Director Babin responded that
MMED would true up power costs every six months and that would be the only change in the
rate, similar to what MMED is doing now with the PPCA.

Clerk Dentino commented that with the unbundled bill you get six months of estimates then
recovery of actual costs and that right now, MMED has this capability with the PPCA. He also
added that the PPCA should be changed monthly. He said that the unbundled bill has more line
items so there would be more items to adjust instead of one lump sum amount. Mr. Seavey
agreed there is a little more accounting with the unbundled bill and that it is busier. He believed,
however, that the PPCA did not call for monthly adjustments because his understanding was that
the Tariff did not read that way. Clerk Dentino disagreed, saying that the Tariff and the DTE
regulations do read that way.
Clerk Dentino inquired as to who would now decide what changes would be made if the bill was
to be unbundled. Director Babin explained that the only component of the rate that would
change in the unbundled bill would be purchased power, which is what MMED does now by
having a PPCA. With an unbundled bill, however, the costs are more transparent: the actual
cost of power is shown as a full charge and not as a base energy charge with a PPCA. He then
answered Clerk Dentino by saying there's no autonomy or discretionary power at the staff level
to set the rate in the Light Department. The cost of power and corresponding PPCA used is
simply a mathematical calculation.
Clerk Dentino commented that the PPCA is supposed to be raised when purchased power costs
go up and lowered when purchased power costs go down. Director Babin responded by saying
the PPCA is estimated and then it is then followed up with a true-up based on actual charges.
Clerk Dentino said that at the last meeting, at which he was not present, Director Babin and Mr.
Seavey stated that when the price of fuel goes up, the price of electricity goes up too. Director
Babin said he does not recall making that specific statement.
Clerk Dentino added that when MMED' s PPCA was raised, other municipals lowered their
PPCA. He said that in New England, energy costs went down 38%, and that the PPCA's for the
North Attleboro Light Department, as well as National Grid and NST AR were also lowered. He
stated that MMED' s PPCA has gone up four times since Director Babin was hired. Director
Babin said that PPCA increases were not attributable to him personally but that it was the result
of a mathematical calculation which indicated that actual purchased power costs were being
under-recovered or projected purchased power costs would be under-recovered by the rates then
in effect.
Clerk Dentino stated that the PPCA was raised in October 2004, August 2005, November 2005
and October 2006, and the latter three raises were attributed to the cost of fossil fuel. He noted
that when spot prices of gas were at an all time low, however, there was no reduction in the
PPCA. He commented that we only adjust up when energy prices go up but when energy prices
go down we make no downward adjustments. He added that approximately 80% of MMED's
purchased power costs were fixed while only 20% was in the open market. Director Babin noted
that the October PPCA increase was solely to collect increased costs associated with the Canal
Generating Station RMR status, which the Board had discussed for several months.
Director Babin said that Mr. Dentino's explanation was an oversimplification of the facts and
that when a power bill comes in, MMED is responsible to pay that bill and has a fiduciary
responsibility specifically cited in the statutes to make sure the cost ofthat power is recovered.
Further, Director Babin added that the ISO New England system is an increasingly complicated
network with over 1,000 points being monitored and prices at each of those points changing on
r
an hourly basis. The 80% of power costs cited by Mr. Dentino is not fixed but rather dictated by
the hourly prices at each of these points. In addition, there are other charges besides the pure
cost of the power, such as the $1.9 million in annual charges that MMED is being billed for the
Canal RMR status, which the ISO assesses.
Clerk Dentino stated that Mr. Babin had stated at a prior Board meeting that one of the reasons
that the PPCA was raised is that reserves were down and free cash was down, and commented
that the PPCA is not supposed to be used to bring reserves up, free cash up, capital up and
depreciation up, it is only to be used to adjust for purchased power costs. Vice Chairman
Amoruso noted that if these were down, then this would occur if purchased power was being
undercollected. Director Babin noted that this affects free cash. Clerk Dentino said this should
be done through the rate and the PPCA should be used to cover the cost of purchased power
only. Mr. Seavey commented that the PPCA is used exactly for the purpose of recovering the
cost of purchased power and has not been used to collect additional monies outside of the cost of
power.
Mr. Seavey mentioned that MMED's auditors noted that the use of the PPCA has been properly
implemented and reconciled and never raised a concern. Mr. Seavey also noted that there have
been no comments from the auditors suggesting that anything was inappropriate in collection of
purchased power costs. Clerk Dentino responded that auditors would not be looking for that.
Director Babin said that the staffs job is to pay bills, then recover the costs ofthose bills through
rates, which are derived from mathematical calculations. Director Babin then added that
questioning the proper performance of these duties becomes an issue of personal integrity. He
said we pay our bills and do the math to recover costs accordingly each month.
r Chairman McCue stated that Clerk Dentino had made his point clear and that Director Babin had
answered his questions.
Town Manager D' Agostino stated that he and Director Babin were looking for the Board to
decide whether MMED's bill should be unbundled. His opinion was that unbundled rates were
the way to go as he was tired of this line of questioning and this would allow people to see
everything broken down on the bill. Chairman McCue answered that he was not prepared to
hear a motion until the next meeting. He also stated that he wanted it to go on record that he was
happy with the Light Department's performance.
Vice Chairman Amoruso voiced his concern about no provision in the rates to pay for the cost of
supplying power for the east side of Town. Director Babin said that he did not wish to address
that particular subject this evening but that it would be addressed at the next meeting.
