Installation Of ARGA Battery Monitoring System - MILFORD Substation

Integration of an Arga Battery Monitoring System into an existing, space-constrained substation control house.
Limited DC circuit capacity requiring a new DC distribution panel.
Need for reliable communication between Arga Monitor and Orion
RTU.
Coordination required across multiple DPL teams (SME, EM,
Protection).
Parallel Spare Transformer project by Worley sharing DC infrastructure, creating interface and documentation risks.

Performed site assessment to validate annunciator space, battery layout, and cable routing.
Coordinated with DPL teams to confirm equipment, alarms, I/O, and communication requirements.
Developed full engineering design including one-lines, wiring diagrams, terminal plans, and cut-in/cut-out packages.
Engineered serial communication using SEL-2886 RS-232 to RS-485 interface to Orion RTU.
Designed a new standard DC distribution panel, including sub-feed
integration and control house layout updates.
Engineered cable routing from battery terminals to annunciator panel
per DPL standards.
Coordinated documentation and interfaces with Worley’s parallel
transformer project.
Delivered phased 60%, 90%, IFC, and close-out engineering
packages.

Identified and resolved DC capacity limitations before construction, reducing field risk.
Delivered a fully coordinated, constructible design aligned with DPL standards.
Enabled seamless integration across monitoring, DC
power, and SCADA systems.
Prevented conflicts between parallel projects through
proactive cross-team coordination.
Provided clear, field-ready documentation supporting safe installation and commissioning.

DST provided data, maps, charts, and calculations in a format easily accessible by ComEd.
DST successfully identified necessary grid upgrades and provided cost estimates for DER integration.
Throughout this program, DST ensured smooth communication and documentation, meeting regulatory and technical requirements for DER interconnection.
