Application Officer Dear Sirs: Re: ATCO Electric Ltd. ("ATCO Electric") 2004 Phase II Distribution Tariff Application Application No. 1349514 ATCO Electric is in receipt of a Notice of Motion, dated September 20, 2004, from the REA/AAMDC seeking further response to certain Information Requests posed during the referenced proceeding. As well, ATCO Electric has received the Board's procedural directions regarding the disposition of this matter, by letter dated September 22, 2004. In responding to this Motion, ATCO Electric is attempting to balance the desire to be as helpful as possible with the clear position that it is entirely inappropriate to seek to revisit or address Phase I matters in this proceeding. The purpose of a Phase II is not to debate revenue requirement items, it is to allocate the revenue requirement to rate classes. The additional clarity provided via the Notice of Motion has enabled ATCO Electric to better understand the purpose of certain Information Requests. Where ATCO Electric has been able to obtain additional information with a reasonable amount of effort, it has revised the Information Response and attached the revised information hereto. In certain other cases, REA/AAMDC reiterates their request for detailed information that is simply not available to ATCO Electric. Notwithstanding the REA/AAMDC assertions, ATCO Electric simply does not possess this information; and can not get it with a reasonable amount of effort. In certain cases it would take months to develop the information and in other cases the information systems required to generate the materials simply do not exist. ATCO Electric submits that the additional information provided herewith represents a reasonable response to the issues identified by the REA/AAMDC. In light of these revised responses, ATCO Electric requests that the REA/AAMDC Motion be dismissed. 0

REA- MDC-ATCO-13 Request: Please identify each REA purchased by ATCO in the past ten years

. For each REA that ATCO has purchased, please provide the purchase price, the net book value (if available), the number of customers, and the number of kilometers of line , and the number and number of transformers and kVA of transformer capacity. Response: ATCO Electric maintains that the matter of ATCO Electric's purchases of REAs is not related to any Phase II issue

. This is a commercial issue between the REA and ATCO Electric. Furthermore, the information requested is not related to the parameters used to allocate costs in this Phase II proceeding . ATCO Electric has also determined that a similar request was made by the REA/AAMDC in the context of ATCO Electric's 1998 Phase II GTA - REA/AAMDC-APL-24 (Attachment 1 ). This information was not considered relevant in the context of that case

. Notwithstanding, similar information was provided by ATCO Electric in the context of the recent Generic Cost of Capital Proceeding in response to an Information Request from the Consumers Group - CG-AE-3 (Attachment 2). Both of these information responses are attached hereto.

Revised: September 20, 2004
REA-AAMDC-ATCO-19 Reference: Section 4, Attachment 2 Request: Please provide documentation of the process by which Atco trades off capital cost against energy losses (load and no-load) when purchasing transformers. Specifically state the value of energy and capacity used when making economic comparisons among bidders.

Response: ATCO Electric considers the "trade-off' referred to by REA/AAMDC to raise issues that relate to Phase I, not Phase II issues

. Notwithstanding, the values requested may have some relation to Phase II. Therefore, ATCO Electric has provided the following information. Calculated transformer losses are stated in the bid documents by vendors, and are evaluated according to the attached Standard (Attachment 1). This Standard is made available to the vendors, and influences the design of transformers that are offered by the vendors.

Revised: September 20, 2004
REA-AAMDC-ATCO-20 Request: What is the total cost of capacitors on the Atco distribution system? Divide into rural and non-rural if available. Identify the specific plant cost category where Atco includes capacitors (e.g., transformers, conductor, etc.), as well as the cost category where they are included in Section 4, Attachment 2 (Foster & Associates study) Exhibits 3, 4, and 5. Response: ATCO Electric reiterates its original response and confirms that this information cannot be obtained with reasonable effort

. Hence, pursuant to s. 29(1)(b) of the Rules of Practice, ATCO Electric does not have the information at the level of detail required in order to be able to provide an answer as to the total cost of capacitors on the Distribution system. Capacitors are included in the Transformer asset account ; this would also be the account/category where they are included in the Foster Associates, Inc. study.

Response: In the materials supporting the Notice of Motion , REA/AAMDC indicate that ".... we have not seen such high surveying costs ....". ATCO Electric is not here to debate the magnitude of surveying costs in the context of this Phase II application

. Furthermore, as previously stated, pursuant to s. 29(1 )(b) of the Rules of Practice, ATCO Electric does not have this information available to it. ATCO Electric does not separately record surveying costs nor does it forecast these costs as a separate entity. The survey costs contained in Section 4 , Attachment 2 are field estimates used for purposes of the classification factor study and are ATCO Electric's best estimate when installing new services.
