STV Secures MTA Contract to Manage Design of 22 New York City Power Facilities

Highlights

• STV has been selected by the Metropolitan Transportation Authority Construction & Development (MTA C&D) to provide general engineering consultant services.

• The assignment covers design management for 22 traction power facilities across Manhattan, Brooklyn, Queens and the Bronx.

• The program includes 10 substations and 12 circuit breaker houses.

• Planned improvements include equipment replacement, energy-efficiency upgrades, structural repairs and advanced monitoring systems.

• The work includes evaluating reversible traction power systems to capture energy generated through regenerative braking.

MTA Selects STV for Traction Power Modernization

Modernizing aging electrical infrastructure across New York City's subway network is the focus of a new engineering assignment awarded to STV by the Metropolitan Transportation Authority Construction & Development (MTA C&D).

STV will provide general engineering consultant services for the design phase of improvements at 22 wayside power facilities across the city's four boroughs: Manhattan, Brooklyn, Queens and the Bronx. The program is intended to improve the reliability and resilience of the electrical network supporting subway operations.

Substation and Circuit Breaker Upgrades

The design program covers 10 substations and 12 circuit breaker houses. Planned work includes repairs, replacements and modernization of traction power equipment.

Key engineering components include:

• Replacement of outdated switchgear, rectifiers, transformers and control systems.

• Energy-efficiency and system resilience improvements.

• A feasibility study for reversible traction power systems that can capture regenerative braking energy.

• AI-enabled thermal imaging and monitoring technologies to identify potential equipment failures.

• Structural, mechanical, electrical and plumbing improvements.

• Hazardous materials removal where required.

STV's responsibilities will include developing project scopes and managing the design program. The existing facilities contain equipment that has exceeded its intended service life, making modernization a priority for reducing unplanned outages and improving recovery from power-related incidents.

Engineering Experience in Transit Power Systems

STV brings more than 40 years of experience in traction power and wayside power engineering. Its previous work includes substation, circuit breaker house and supervisory control and data acquisition (SCADA) system upgrades for transit agencies across North America.

Relevant projects include Second Avenue Subway Phase 2, Grand Central Madison, the CATS LYNX Blue Line Extension, Purple Line Extension Section 3 Stations and Tunnels, Harrison Place Substation Design-Build and Coney Island Yard.

The assignment draws on STV's regional transportation engineering workforce, which includes nearly 1,000 professionals across the Metro New York area.

Why It Matters

The design program addresses aging electrical infrastructure that supports daily subway operations across New York City. Modern traction power equipment, improved monitoring and energy recovery evaluations are key components of the planned upgrades.

For infrastructure owners and contractors, the program highlights the engineering and systems integration requirements involved in modernizing operational transit facilities while maintaining the reliability of an active transportation network.
