WORKPAPER 3.1 – MODERN GRID COSTS FOR RHODE ISLAND ONLY DEPLOYMENT

SCENARIO

While National Grid’s affiliates in both Massachusetts and New York have proposed similar grid modernization projects, these plans have not yet been approved by the applicable regulatory agencies. Therefore the Company is presenting two scenarios of deployment: a Rhode Island only deployment scenario presented in Workpaper 3.1 and a multi-jurisdiction deployment scenario presented in Workpaper 3.2. It should be noted that the Company is presenting only the multi-jurisdiction deployment scenario for the DSCADA and ADMS project.1

3. CONTROL CENTER ENHANCEMENTS

3.1 DSCADA AND ADMS

See Workpaper 3.2 – Modern Grid Costs for Multi‐Jurisdiction Deployment Scenario. 

                                                            1 The Company operates a common distribution control center for its Rhode Island and Massachusetts operations, so a coordinated deployment with Massachusetts is the only feasible and cost effective deployment option.

Project Element Description RI Estimate

DG

This effort will focus on the DG data model and functionality in GIS to ensure that 

the system will be capable of supplying the information required by DSIP 

investments.   Beyond the system review and development, full population of DG 

locations and attributes will be completed.

$32,778

General Data Collection

This effort is focused on improving data quality of existing data through leveraging 

issues found during model builds, operating knowledge and known areas of 

concern.   The intent of this effort is to eliminate errors related to network 

topology, attribute level inconsistencies and to apply additional system 

validations to drive improved data quality moving forward.

$1,060,102

New Attributes

Will be made available and where it will be stored will be developed and 

migration or creation of this data will be completed.   Additionally, validations and 

cross system keys will be established to drive quality and synchronization.

$454,365

Networks

To address known needs related to modelling downtown GIS networks this effort 

would focus on creating an underground focused data model, population of 

available data (including potential field checks) and integration of inspections 

with GIS for enhancing data quality moving forward.

$845,169

Secondary

GIS currently does not fully model secondary systems.   This effort would be a 

multi‐year effort to fully populate the system.   Additional considerations will be 

updating connect model export techniques to get the data to downstream 

systems, including ADMS.

$481,865

Substation Modelling

Substation assets are kept in the Cascade system but only peripherally modelled 

in GIS.   This effort would interface these systems – creating a GIS substation data 

model that incorporates network connectivity considerations between 

Transmission and Distribution to provide data that will be used to inform ADMS 

and load flow planning models

$93,737

Connected Model Export

This effort will seek to replace or enhance current capabilities utilized to export 

information from GIS to downstream systems including CYME, OMS and ADMS.   

The current process is highly customized but very use specific and does not meet 

emerging and future needs.

WORKPAPER 3.2 – MODERN GRID COSTS FOR MULTI-JURISDICTION DEPLOYMENT SCENARIO

While National Grid’s affiliates in both Massachusetts and New York have proposed similar grid modernization projects, these plans have not yet been approved by the applicable regulatory agencies. Therefore the Company is presenting two scenarios of deployment: a Rhode Island only deployment scenario presented in Workpaper 3.1 and a multi-jurisdiction deployment scenario presented in Workpaper 3.2. As can be seen in Table 1.1, many of the proposed Grid Modernization projects support multiple operating companies and significant cost synergies can be realized if these investments are coordinated across the operating companies.

Table 1.1: Grid Modernization Multi-Jurisdiction Deployment Cost Allocations

Total multi-jurisdiction project cost calculations are presented below. The Rhode Island portion of these costs can be obtained by multiplying these total multi-jurisdiction costs by the relevant Rhode Island Allocation factor presented in Table 1.1 above. 

1. SYSTEM DATA PORTAL

No cost synergies can be realized for this project, so multi-jurisdiction deployment is not proposed. See Workpaper 3.1 – Modern Grid Costs for Rhode Island Only Deployment Scenario for project cost details.

2. FEEDER MONITORING SENSORS

No cost synergies can be realized for this project, so multi-jurisdiction deployment is not proposed. See Workpaper 3.1 – Modern Grid Costs for Rhode Island Only Deployment Scenario for project cost details.
