Seton Ridge Development – 12 MW Load Impact Study

AI summary This document refers to a Load Impact Study conducted for Seton Ridge Development, which involves a 12 MW load impact. The study likely assesses the effects of this development on the electrical grid.

3 1 Request IR-5: 1 distribution system planning objectives. As a result, a detailed overhead design was 2 not developed, and a corresponding lifecycle cost assessment was not prepared. 3 4 In general, as discussed in IR-6, underground dis...

AI summary The document discusses the lack of detailed overhead design and lifecycle cost assessment for the Seton Ridge project. It also notes that underground distribution systems have higher initial costs but may reduce outage risks. An economic analysis model was not prepared, and references are provided for further details.

Replacement of Existing Systems - The Company will be responsible for costs associated with the best (generally lowest cost) supply option should an 1 2 3 4 5 6 7 underground system (or any part thereof) have to be replaced. Where this opt...

AI summary The Company is responsible for replacing existing underground systems with the lowest-cost supply option. If overhead supply is the best option but the customer prefers underground service, they must cover the cost difference. The Seton Ridge development requires underground infrastructure due to urban design constraints and long-term load growth needs.

(b) The feeder conversions and upgrades identified in the Seton Ridge Load Impact Study were developed as system planning recommendations to accommodate forecast load growth and support the future conversion of the Rockingham area from 12....

AI summary The Load Impact Study for the Seton Ridge development outlines system planning recommendations to accommodate load growth and future voltage upgrades but does not specify infrastructure type or detailed design. NS Power incorporated the forecast load into its analysis and collaborated with the developer on an underground servicing approach as the project evolved.

performance in each of these years. 1 Request IR-16: 2 (b) The 23H-Rockingham conversion from 12.5kV to 25kV is part of the long term system 3 plan for this area and would be required regardless of the Seton Ridge development. 4 However, i...

AI summary The text discusses the conversion of the 23H-Rockingham system from 12.5kV to 25kV, which is part of a long-term system plan and dependent on the Susie Lake substation. It also raises a question about the applicability of regulations to underground systems, as opposed to overhead systems, and requests clarification and updates to relevant sections.
