Purpose
Q. What is the purpose of your testimony?
A. The purpose of my testimony is to state and explain TEC-RI’s position on two points.
Q. Could you state these two points?
A. The two points are as follows:
1. TEC-RI supports National Grid’s proposal to exempt Large and Extra Large rate classes from
the gas RDM.
2. TEC-RI proposes the elimination of back-up rates through the RDM.
Exempt Large and Extra Large Users from Gas RDM
Q. Could you explain TEC-RI’s position relative to your first point, the exemption of large and extra large gas customers from the RDM?
A. TEC-RI shares the same concerns expressed by National Grid. These concerns are as follows:
There are small numbers of customers in these four rate classes (Large Low Load, Large High Load,
Extra Large Low Load and Extra Large High Load) and a large range of use. In view of this, average
revenue per customer could change significantly in each of the four Large/Extra Large rate classes due to
changes in use associated with just a few customers and unrelated to energy efficiency.
Using information provided in National Grid’s response to DIV 1-6 it is apparent that there is a clear and
dramatic change in the number of customers and the distribution of gas use among those customers
when comparing the Residential, Small and Medium Commercial rate classes with the four Large and
Extra Large rate classes. For example:
· In the Extra Large High Load class, there are 68 total customers and only 6 customers account
for 52% of therms used.
· In the Extra Large Low Load class, there are 24 customers and one customer accounts for 35% of use and three customers account for 51% of therms used.
· For Large High Load customers, 7 of the 140 customers account for 10% of use,
· In the Large Low Load class, 21 of the 358 customers represent 12 % of the therms used.
This can be compared to the Medium rate class where there are 3,371 customers and the total use of
the largest 133 customers in this class equal only 10% of the total use of this rate class. The number of
customers in the remaining rate classes is as follows:
· Residential Non-Heat, 27,000,
· Residential Heat, 194,000.
· Small C&I, 17,000.
I also note that the Medium rate class ranges from 5,000 therms to 35,000 therms use per year. By
comparison, the Large class ranges from 35,000 therms to 150,000 therms per year and the Extra Large
class is anything over 150,000 therms per year. Given these use ranges in the customer classes it is easy
to see why fewer customers could have a greater effect on average use within the Large and Extra Large
rate classes.
To illustrate this point I refer to the Extra Large Low Load rate class. If the largest customer were to
leave that rate class or go out of business the average use of the rate class would decrease by 35%. The
average use in the rate class would drop from 413,954 therms per customer to 269,124 therms per
customer.
As I illustrated in the previous paragraph, changes in use by just a few customers could have significant
impacts on RPC. These changes in use could occur for several reasons including: migration
between rate classes, fuel switching and the closing or relocation of a business, which is an unfortunate
but real concern in this economy. None of these reasons are included in the eight purposes for the
RDM listed in the Decoupling Act (R.I.G.L. 39-1-27.7.1). Due to the characteristics of these four Large and
Extra Large rate classes, as previously described, it is likely that the RDM could be used to compensate
National Grid for reductions in gas sales for reasons other than those enumerated in the Decoupling
Act. This would be an improper application of RDM and not the intent of the law.
Q. Do you have any other reasons for exempting the Large and Extra Large users from the gas RDM?
A. Yes I do. I also agree with National Grid’s concern relative to the effect of the RDM on the CIAC
(Contribution in Aid of Construction) for Large and Extra Large rate classes as stated on Page 14-16 of its
Joint Testimony and its response to DIV 1-13(d). With the RDM there does not seem to be much if any
basis for the company to assist in expanding service for existing customers because any increase in
revenue for existing customers would be returned to customers through the RDM adjustment and
would not be used to help to defray the cost of expanded gas service. This would likely have its
greatest impact relative to larger customers in a rate class where the potential for load growth would
be greatest but also the most costly to upgrade gas service. Without the assistance of National Grid in
defraying costs of service upgrades through the CIAC the ability of customers to switch to cheaper and
cleaner gas would be hampered. This would be detrimental to the expansion of existing businesses as
well as adding new businesses to the system and for the creation and retaining of jobs. In summary, this
is bad for economic development and has bad environmental consequences. The RDM should not be
used to take away options from businesses who are trying to survive in this economic downturn by
switching to a cheaper and cleaner fuel option.
Q. Does the State law permit this exemption of Large and Extra Large gas customers?
A. Yes. R.I.G.L 39-1-2.7.1 (e) (2) specifically allows the commission to exclude gas customers in the large
commercial and industrial rate classes from the RDM.
Q. Do you have any other comments about this point?
A. No
Elimination of Back Up Rates
Q. Could you explain TEC-RI’s position relative to your second point, the elimination of back-up rates?
A. Decoupling, as already designed and proposed, will recover revenues due to the loss of energy sales
from Distributed Generation (DG) projects (self generation). In fact, DG will be indistinguishable from
energy efficiency under the current RDM design with the exception of back up rates.
With the proposed RDM, even though the disincentive to DG has been removed for the utility, there is
still a disincentive in place for the customer related to sales that should be removed through the RDM.
This is the back up rate under the National Grid Electric tariff. Our recommendation is to
eliminate backup rates and use the RDM Adjustment Factor under decoupling to recover revenues lost
due to the elimination of backup rates just as it does the revenues lost due to reductions in demand
sales revenues for energy efficiency. Furthermore, we recommend that DG customers are
only charged for actual use of the distribution system at peak hours and that use for scheduled and
unscheduled maintenance not be subject to the demand ratchet clause.
Q. Can you explain how back up rates work?
A. Yes. If a DG (distributed generation) project of over 30 KW is installed by a customer, the customer
goes on back up rates. Under these rates the customer pays for its new lower level of demand plus the
amount of the reduction. In other words, the customer pays for its former level of demand even though
the customer made an investment to save energy and energy costs which results in a reduction in actual
demand.
Q. If a customer reduced its demand by the same amount due to energy efficiency as it did through DG would the customer also pay back up rates?
A. No. If the customer reduces demand through energy efficiency by the same amount as it did through
DG the customer would only pay for its actual new lower level of demand. The customer would not be
charged back up rates for the reduction in demand.
Q. If a customer reduced its demand due to cut backs in production will it have to pay back up rates?
A. No. As with energy efficiency, if a customer reduced its demand due to production cut backs it would
only have to pay for its actual new levels of demand. The customer would not have to pay back up
rates for the reduction in demand.
Q. Can you give an example to illustrate this point?
A. Yes. Let’s say a customer has a demand of 5,000 KW and it reduces it to 3,000 KW. If the customer
did it through energy efficiency or due to production cut backs it would pay for 3,000 KW of demand.
If the customer did it by investing in a 2,000 KW generating unit to generate his own power he would
still pay for 5,000 KW in demand.
Q. How much would it cost the DG customer in back up rates?
A. In the case of this example it would cost the customer $64,560 per year.
Q. How much would a customer who reduced their demand in the same amount due to energy efficiency or production cut backs pay for a 2,000 KW reduction?
A. It would cost the customer nothing, $0.00 per year.
Cost and Bill Impacts of Eliminating Back Up Rates
Q. Can you explain how much revenue would have to be recovered from the elimination of back up rate revenues and how it could be done?
A. With only 4 customers[1] on back up rates (B-32 and B-62) there is a very low amount of revenue that
comes to National Grid that would have to be recovered. National Grid’s response to TEC-RI data
request 2-3 indicates that only $250,393.36 in demand charge revenue was collected from B-32 and
B-62 rate classes in 2010.
Using the electric RDM Adjustment Factor Calculation methodology, the amount of $250,393.36
divided by 7,801,501,217 kWh would result in an adjustment factor of $ 0.000032/kWh. This will add
only 1.6 cents per month to the typical residential customer’s bill. This cost pales in comparison to the
price we will be paying for electricity from other options. For example, the New Shoreham Off-shore
Wind project, at 24 cents per kWh it averages $.0026/kWh for each and every customer.[2] For a typical
residential customer, the New Shoreham Off-shore Wind project costs $1.30 per month. This is 81
times the cost of eliminating the back up rate.
Q. How does the cost of eliminating the back up rate compare with other charges?
A. The table below shows the impact of the elimination of the 2010 back up rate revenues on the
typical residential customer using 500 kwh per month. It also makes some comparisons to some other
charges including the Transmission Charge, DSM program, the Renewable Energy Fund (REF), the 2012
ISR Plan[3], the New Shoreham wind project and finally to lost revenues from 30 MW of Distributed
Generation projects (the same size as New Shoreham wind).

Q. Has National Grid ever discussed the elimination of back up rates in their RDM proposal?
A. Yes. Under a decoupling plan submitted under docket 4065 National Grid did discussed eliminating
backup rates. I quote Howard Gorman who was the expert witness speaking for National Grid on
Docket 4065. Mr. Gorman stated for the record that:
“The current backup service rate structure may discourage customers from installing
distributed generation (other than for large solar and wind systems which are exempt from
backup service charges and are eligible for net metering generation credits) because
customers incur the same distribution charges no matter the mix of supplemental service and
backup service at their peak hours. This would be contrary to the objectives of the Company
and the public policy of Rhode Island. Therefore, if the Commission approves the Company’s
revenue decoupling proposal, the Company may propose to terminate Rate B-32 and transfer
all backup service customers to Rate G-32, under which customers are charged only for actual
use of the distribution system at their peak hours. The company’s proposed RDM would
provide the Company the authorized return on assets even with a rate design that promotes
distributed generation.” (at page 21).
TEC-RI agrees with the principal points of Mr. Gorman’s statement including:
· The current backup service rate structure may discourage customers from installing distributed generation,
· continuation of backup rates would be contrary to the objectives of the Company and the public policy of Rhode Island,
· the company’s proposed RDM would provide the Company the authorized return on assets even with a rate design that promotes distributed generation.
As a point of clarification I want to note that not all backup service customers are on Rate B-32. TEC-RI
clarifies Mr. Gorman’s recommendation above by noting that our recommendation is that Rate B-32
customers should be transferred to Rate G-32 and Rate B-62 customers should be transferred to Rate
G-62.
Q. Did National Grid include the elimination of back up rates in this filing?
No. In their response to TEC-RI data request 1-1 National Grid deferred to the Commission calling the
elimination of backup rates “….a policy decision for the Commission to make.” National Grid also states
in TEC-RI 1-1 that, “Assessing charges for back up service is a concept not directly related to
decoupling.”
TEC-RI believes that the Commission has the latitude to decide under the current docket and that at
least two of the eight stated purposes of the Decoupling Act are to implement Distributed Generation
and Reduce Demand and therefore this docket #4206 is appropriate for consideration of the elimination
of back up rates.
In addition, TEC-RI believes that National Grid is required to eliminate back up rates since a primary
purpose of the Decoupling Act is to fully decouple revenues from sales. Revenues from back up rates
are included in National Grid’s base rates as a distribution charge under docket 4065. This means that
National Grid did not fully, “break the link” between revenues and sales as they assert in their filing
under this docket.
TEC-RI believes that National Grid correctly stated in their testimony under docket 4065 that the RDM
should be used to recover lost revenue from the elimination of backup rates. TEC-RI elaborates on
these points below.
State DG Policy and Legislation
Q. What is the State’s policy relative to encouraging distributed generation and the elimination of backup rates?
A. RIGL 39-1-27.7 “System Reliability and Least Cost Procurement,” calls for DG to be included in the
State’s energy strategy and calls for back up rates that facilitate the development of DG.
Q. Is DG permitted under the State’s Decoupling Act, R.I.G.L. 39-1-27.7.1.?
A. The Decoupling Act not only permits it but it requires it. Paragraph (a) of the Act “finds and declares
that any decoupling proposal submitted by an electric distribution company …… shall be for the
following purposes: …..(2) Achieving the goals established in the electric distribution company’s plan for
system reliability and energy efficiency and conservation procurement as required pursuant to
subsection 39-1-27.7(c).” The EERMC submitted its revised System Reliability Procurement Standards as
called for by this section of State law on March 1, 2011 calling for a significant emphasis on NWA (non-
wires alternatives) including distributed generation such as CHP, wind and solar. This docket provides an
opportunity to take a step towards implementing those recommendations in a very timely fashion by
eliminating back up rates now.
Q. Does the Decoupling Act allow for the recovery of revenues due to the loss of sales?
A. Yes. The first paragraph of the Act states that, “The general assembly finds and declares that
electricity and gas revenues shall be fully decoupled from sales pursuant to the provisions of this
chapter…”
Q. How does this relate to back up rates?
A. Up to now, when an electric utility lost revenues due to self generation by a customer (DG), the back
up charge was used to recover some of those lost revenues from individual customers who invested in
DG. This is a disincentive to the development of DG. Under decoupling, this is no longer necessary. The
primary purpose of decoupling is to separate sales from revenue and to recover lost revenues through
the RDM. This is not optional. Note that the Act says that, “electricity and gas revenues shall be fully
decoupled from sales.” It does not say that there is an option to partially decouple revenues from sales.
Q.Is the purpose of back up rates to recover revenues lost due to a reduction in sales?
A. Yes. As with energy efficiency, self generation results in a reduction in demand due to a
reduction in sales. But unlike energy efficiency, back up rates are used to recover some of those lost
revenues from DG.
Q. Isn’t this the purpose of the Decoupling Act?
A. Yes. It is one of its main purposes, to break the link between sales and revenues.
Q. Is the reduction in demand due to energy efficiency included in the RDM proposed by National Grid?
A. Yes it is.
Q. How does a reduction in demand due to energy efficiency differ from a reduction in demand due to DG?
A. It doesn’t except for in the cost recovery mechanism proposed by National Grid under this docket.
The current rate structure with back up rates discourages DG. If it were put under the RDM this
disincentive would be eliminated. Under the current rate structure the customers who take the
initiative to self generate would be charged at least $2.69 per KW of reduction or about $617,000 per
year for a reduction of 19,142 KW. (This is the same demand reduction in the 2011 Energy Efficiency
Program Plan submitted by National Grid and approved by the RI PUC). This is a tremendous and unfair
disincentive to customers who want to take control of their energy costs and to implement a State
Policy that helps all ratepayers.
Q. Is Distributed Generation comparable to energy efficiency?
A. Yes. In fact, incentives for distributed generation in the form of Combined Heat and Power projects
have been included in the last three Energy Efficiency Program Plans that were prepared by National
Grid and the DSM Collaborative and approved by the RI PUC. These plans are submitted under 39-1-
27.7 (the Least Cost Procurement provisions of the Comprehensive Energy Conservation, Efficiency and
Affordability Act of 2006).
Q. Does this Energy Efficiency Program Plan include any KW demand reductions?
A. Yes. The 2011 plan includes 19,142 KW annual savings. Each plan through 2017 will probably include
at least this level of annual demand reduction.
Q. Will this demand reduction from efficiency programs result in a loss of revenue from customers?
A. Yes.
Q. Will this reduction of demand from efficiency programs be subject to the back up rate?
A. No.
Q. Then how will this loss of demand revenue from efficiency programs be recovered?
A. Under National Grid’s filing in this docket it will be recovered through the RDM which is charged to all
customers and all customer classes.
DG and the Benefits of Demand Reduction
Q. Do reductions in demand help all ratepayers?
A. Yes.
Q. Can you explain?
A.Yes. At a meeting of the ISO (Independent System Operator) Consumer Liaison Group that I attended
on March 3, 2011 an ISO staff person did a presentation that showed that that $4.6 billion will have
been spent on Transmission upgrades in New England from 2007 through 2011. Another $4.3 billion is
being planned for 2012 through 2014 for a total of $8.9 billion over this period. [4] This same report says
that Transmission charges in New England have increased 225% between 2005 and 2009 from .4
cents/kwh to .9 cents/kWh. Transmission costs are passed through to ratepayers under the
Transmission Charge on their bill. My January 2011 bill on the A-6 residential rate shows a
Transmission Charge of 1.569 cents/kWh.
ISO forecasts that Rhode Island’s peak demand (summer) will increase by 1.3% annually over the
next decade. ISO has also reported that on July 6, 2010 Rhode Island hit its fifth highest peak on record
and that peak demand records were set for the months of May and September in 2010. If these trends
continue and are met strictly by the addition of transmission facilities then, these Transmission costs will
continue to rise and continue to be passed through to all customers.
In reviewing my own residential bill for my home I was shocked to discover that 24% of my Total
Delivery Services charge was accounted for by the Transmission Charge.[5] As shown in the Table on page
9, a typical residential customer in Rhode Island pays $7.85 per month on their electric bill for their
Transmission Charge. Reducing demand through DG, energy efficiency, and demand response will help
control these costs for all rate payers by reducing, or potentially eliminating, the need and cost of
increased Transmission capacity in the future.
Q. How else does DG help all ratepayers?
A. For a typical residential customer, in addition to helping them to control or eliminate the cost of
Transmission capacity upgrades as discussed above, it helps the local economy and the environment.
Q. How does DG help the local economy?
A. It gives businesses more options and more flexibility for dealing with high energy costs in Rhode
Island which are among the highest in the Nation. This helps businesses to stay in Rhode Island, retain
jobs and perhaps expand jobs for ratepayers. It will also provide local jobs for the installation, operation
and maintenance of the equipment.
Q. How does DG help the environment?
A. DG gives off less carbon emissions than conventional bulk power plants. DG plants are often either
renewable energy or CHP (Combined Heat and Power) systems. Renewable energy systems such as
wind or solar have no carbon emissions. CHP usually operate at an efficiency over 60% compared to
conventional bulk power plants that operate at 30 to 35% efficiency. Bulk power plants also require
Transmission lines which can create land use issues for rights-of -way.
Q. Is one of the purposes of the Decoupling Act to reduce long term electricity demand?
A. Yes. 39-1-27.7.1 (a) (3) specifically calls for “Increasing investment in least-cost resources that will
reduce long-term electricity demand.”
Q. Would you say that elimination of the back up rate for DG will help to level the playing field?
A. Yes. TEC-RI is not asking for favored treatment of DG. We are simply asking for equal treatment.
Back up rates keep DG at a competitive disadvantage. With the elimination of back up rates through
the RDM, DG could then develop based on the market without being artificially hampered. The market
would determine whether efficiency, demand response, bulk power purchases, upgrades to the
Transmission system , DG or some combination of them all is the best option.
Q. Have back up rates been eliminated in any other nearby states?
A. Yes. In the Commonwealth of Massachusetts back up rates have been eliminated in the National Grid
territory for about 10 years.[6]
Closing Comments
Q. Do you have any further comments?
A. Yes I do. As everyone knows, RI has been in a deep economic recession for a couple of years now.
Everyone knows that we have among the highest unemployment rates in the Nation at over 10%. The
positions that TEC-RI is taking in this docket, if adopted by the PUC, will give businesses more options
and more flexibility to survive in this economy and hopefully to eventually expand. This will help
businesses to retain jobs and hopefully grow more jobs. We hope that the Commission bears in mind
that ratepayers are customers who need to keep jobs or get jobs. The Rhode Island economy is very
fragile at this time and businesses are looking for some indication that government policy makers and
decision makers understand this and want to help. Small decisions matter (as the expert quoted below
indicates). Collectively, a series of small decisions in pursuit of a clear policy objective matter a lot by
sending a clearer message. TEC-RI has presented two reasonable positions that will help Rhode Island
businesses and help keep and create jobs for ratepayers.
To underscore the fragility of the Rhode Island economy I will point to an article relevant to energy costs
and their effects on business and the economy that appeared in the March 1, 2011 Providence Journal,
front page. The article was about the effects of increased oil prices on the Rhode Island economy (due
to events in Egypt and Libya). Local experts on the Rhode Island economy were quoted as follows:
“Rhode Island is in a recovery, but we’re in a very shallow recovery. Rhode Island has virtually no margin for error.” - Leonard Lardaro, Professor of Economics at the University of Rhode Island.
“The big concern at this point is that this could lead to a double-dip recession in Rhode Island.” -Edward M. Mazze, distinguished professor of business administration at the University of Rhode Island.
TEC-RI’s recommendations will give RI businesses a little more margin for success, help the environment
and at a fraction of the cost of other energy options.
