This scope of this will include:

  • Model refinement such as use-ability, dashboarding & data inputs
  • Presentation of outputs (considering use of mapping tools to identify “hotspots”)
  • Development of enhanced intervention methodology
  • Establishment of “scheme allocation methodology” across all asset categories (just Primary Plant so far)
  • Plant optimisation to achieve target levels of risk (with risk constraints)
  • Plant optimisation to achieve unit cost reductions
  • Alignment to the requirements of the Common Methodology

Development of the modelling capability around the high-volume low-value asset categories Based on our current understanding of NPg requirements decisionLab have developed this costed proposal for consideration.

The objectives of the project are:

·         To implement general model refinement such as usability, dashboarding & data inputs

·         Presentation of outputs (use of mapping tools to identify “hotspots”)

·         Revisit intervention methodology

·         Enhanced investment planning:

o    Revisit scheme allocation methodology (investment planning-focused workshops)

o    Optimise investment scenarios to achieve target levels of risk (with risk constraints)

o    Optimise  investment scenarios to achieve unit cost reductions

o    Scheme associations across all asset categories

o    Planned interventions across all asset categories (just Primary so far)

·         Align risk quantification to the requirements of the Common Methodology

·        Develop the modelling capability around the high-volume low-value asset categories

The project will be considered delivered once Northern Powergrid is in receipt of the final models with the agreed functionality.

(1) Tool Enhancement

  • Optimise to achieve target levels of risk (with risk constraints) : Enhanced functionality over and above existing methodology successfully added to the existing model
  • Develop NPg modelling capability around the high-volume low-value asset categories: HV cables, LV cables and pole mounted transformers added to the modelling environment
  • Implement enhancements to functionality identified in Phases 1 to 4 during 2014/15: Enhanced functionality to existing methodology successfully added to the existing model

(2) Methodology Enhancement

  • Evaluate and Improve underlying intervention methodologies: Internal workshops held to inform improved intervention modelling. Functionality added to models.
  • Model synergies which can deliver efficiencies: Enhanced functionality over and above existing methodology successfully added to the existing model

(3) Investment Planning

  • Optimise to achieve unit cost reductions: NPg able to carry out unit cost scenario analysis using the AIMMS model
  • Incorporate an investment planning perspective: Enhanced functionality (over and above existing methodology) identified through targeted workshops and successfully added to the existing model

(4) Risk Outputs and Calculation

  • To align to Common Methodology: Risk calculation methodology revised in accordance with the requirements of the Common Methodology
  • Enhance model output functionality: The current sets of output pages would be fully reviewed with wider members of the NPg team.
