Introduction

Analytical approach to get the most out of technology investments.

Benefits:

– Determine the best technologies, where they should be deployed, and to what degree.

– Recognize the driving factors and changes that makes these the best solutions.

– Defendable plan of action (project benefits are based on detailed analytics).

Optimized Spend

Model Overview

TIP can be updated as the system changes or solution costs change.

All input data, algorithms, and assumptions will be provided in a user friendly benefit cost model.

Project Approach

Data Collection– Coordinated effort to define technologies, feeder & system

characteristics, and financial assumptions.

Algorithms Development – DNV GL has tools and previous project experience

relating feeder characteristics and solution benefits.

TIP Model Customization - Define global and project specific

variables, incorporate algorithms.

Optimal Plan – Recommended plans based on various levels of spend

and focus areas.

Algorithms Development

Algorithms relate detailed project drivers to program benefits.

Illustrate the amount of equipment deployed and benefit / costs associated with roll-out.

This approach results in a robust benefits and costs assessment.

Optimal Plan

Findings will illustrate optimal solutions under various conditions:

– Cash Flows.

– Diminishing returns.

– Detailed feeder results.

– Combined projects (projects will interact and provide synergy).

– Time varying factors (load growth, renewables, electric vehicles etc.).

Features

Provides a list of recommended feeders and technologies applied on a benefit cost basis.

Optimal spend curve shows the value for a given level of spend.

Allows project solutions to be shown individually or combined.

Uses utility data to provide a customized solution.

Output is easy to understand and use in decision making.

Assumptions can be changed to understand the sensitivity to the utility environment.

Provides detailed output that is available when needed but summarized if not.

Provides a tried and tested approach. Successfully deployed with other utilities.

Filtering - Turn technology on and off to see the interactions, investigate solutions, combined benefits and costs.

Example

Find the top 3% of feeders in terms of benefit to cost for fault current indicators, assuming they are distributed equally along the feeders.

Tabular and Graphical Results

Findings

Each utilities' financial, operating and regulatory environment is unique; however, there are several common themes.

The following are high-level lessons learned from smart grid solutions benefit cost modeling projects with utilities:

– A majority of the benefits are achieved by applying technology to a subset of the system

(i.e. the top 10% of feeders may account for 50% of the possible benefits, similar to the

80/20 rule).

– Dispersing project solutions is more effective than lumping them (e.g. it is better to place

fault current indicators on the top 10% lightly than the top 5% more densely).

– Combined solutions are more attractive (e.g. there are often synergies between solutions,

communications costs are shared between projects).

– Changes in company priorities and financial parameters have a big impact on results (e.g.

changes in future needs alters project outlook, it is important to look forward and

understand variability and trends).
