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.

Benefits

(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.
