AI summary ENSC's 2012 DSM Plan included a cost allocation approach for NSPI ratepayers based on a 2009 settlement agreement. The Board ordered ENSC to review and propose a new methodology for cost allocation in conjunction with its 2013 DSM Plan.

On June 30, 2011, the Board ordered ENSC to develop and file, no later than September 30, 2011, its policy to track time and costs for electric and other fuel mandates. The June 30, 2011 Board Order also directed ENSC to undertake the nece...

AI summary In 2011, the UARB ordered ENSC to develop a policy for tracking time and costs related to electric and fuel mandates, and to consult stakeholders on cost allocation for DSM programs. ENSC hired Elenchus to develop a cost allocation model, review DSM cost allocation approaches, prepare preliminary cost tables, and analyze rate and bill impacts.

With this Application, ENSC is seeking: - approval of the 2013-2015 DSM Plan, provided as Appendix A, and its associated multi-year framework as outlined in Section 3 - approval to transfer the responsibility for filing the annual DCRR adj...

AI summary ENSC's cost allocation processes involve using a Cost Allocation Model (CAM) for true-up adjustments to ensure accurate recovery of ratepayer-funded program costs. Unlike regulated utilities, ENSC's CAM reflects unique characteristics, such as non-capital intensity and program-specific expenditures, while adhering to cost causality principles. The model is divided into two parts, with preliminary allocations based on planned costs rather than CAM inputs.

3 PRINCIPLES ON WHICH THE ENSC CAM IS BASED The goal in developing the ENSC cost allocation model has been to ensure that it is compliant with Generally Accepted Regulatory Principles and with standard Canadian regulatory practices. The "p...

AI summary The ENSC Cost Allocation Model (CAM) is based on three principles: fully allocating direct, support, and administration costs; applying cost causality to assign responsibility for costs; and using proportional allocators when direct causality is unclear. Unlike regulated utilities, ENSC has few common costs, allowing most expenses to be directly allocated, except administrative costs, which use fair allocators. The model emphasizes credible accounting data and empirical analysis for cost allocation.

AI summary ENSC's Cost Allocation Model (CAM) determines EDSM program costs recoverable from NSPI customer classes after audit. It uses fully allocated costing principles, dividing costs between taxpayer- and ratepayer-funded programs, with further allocation to ratepayer classes. The UARB's 2011 Order guides first-tier allocation, while second-tier allocations depend on program-specific cost categories.

AI summary ENSC's cost allocation model (CAM) is reviewed for accuracy in allocating ratepayer-funded program costs. The CAM uses true-up adjustments to reflect actual costs, with preliminary allocations based on planned budgets. ENSC's unique non-capital-intensive nature influences its CAM, which adheres to cost causality principles. Elenchus developed a two-part model tailored to ENSC's operations.

3 PRINCIPLES ON WHICH THE ENSC CAM IS BASED The goal in developing the ENSC cost allocation model has been to ensure that it is compliant with Generally Accepted Regulatory Principles and with standard Canadian regulatory practices. The "p...

AI summary The ENSC CAM is designed to comply with regulatory principles, allocating all costs fully, using cost causality, and pooling costs proportionally. Unlike regulated utilities, ENSC has few common costs, allowing direct allocation of most costs. Administrative costs are allocated using fair allocators. Credible accounting data and empirical analysis are emphasized for accurate cost allocation.

AI summary The Cost Allocation Model (CAM) is used post-audit to allocate ENSC's EDSM program costs to NSPI customer classes based on cost causality. ENSC's methodology divides customer classes into taxpayer-funded and ratepayer-funded tiers, with further allocation within ratepayer-funded programs. The UARB's 2011 Order guided the first-tier allocation, though the report focuses on this tier, noting most costs are later allocated to NSPI rate classes.
