In New Jersey, we upgraded a 41-mile 230kV/138kV transmission line, strengthening the regional electrical grid and withstanding weather damage.

In New Jersey, we worked on a new plant and replaced outdated coal generating units with a 590 MW dual-fuel combined-cycle power plant, featuring GE’s 7HA.02 gas turbines and steam turbines housed in a dedicated turbine building.

In New Jersey, we built a 69kV substation in 4 months ultimately improving electrical service to businesses and residents.

A 20 MWh battery storage system that boost grid reliability and involves civil construction, setting up utility poles, and electrical installations of an 800 kVA transformer, switchgears, and underground raceways.

We provided turnkey mechanical, electrical, and civil construction to deliver a biochar byproduct and methane-capturing facility that handles 130,000 tons of biosolids from landfills annually.

Advancing New Jersey’s RNG efforts, this plant captures and converts landfill gas into clean energy, reducing CO₂ and methane emissions.

From 2018 to 2022, we were the contractor of choice for the local utility in Maryland. We upgraded our client’s aging gas system by installing new gas mains and new services (including HDPE and steel gas mains) to improve reliability, safety, and capacity.

From 2018 to 2022, we upgraded 6 miles of natural gas systems in a residential area of Drexel Hill on behalf of a regional utility service provider. As a result, we delivered safe, reliable gas services on behalf of our client.

We are currently working to resolve poor power connectivity issues for residents in Pennsylvania by replacing and upgrading an aging electrical network.

Relocating a 15 kV underground system beneath a former steel mill using horizontal directional drilling (HDD) under train tracks and installing switches, raceways, and 130,000 feet of cable.

In Pennsylvania, we mobilized a fractionator unit on behalf of a natural gas client to improve the function of the plant and deliver expanded gas services.

In 2018, under a multiyear contract, we assisted the host utility with their network overhaul by fabricating and installing regulator stations and large-diameter, high-pressure steel gas mains throughout the Westchester County service area.

In August 2020, Hurricane Isaias struck the Northeast and Mid-Atlantic regions, causing 2 million customers to lose power. We rapidly deployed more than 350 employees, delivering timely, efficient restoration and critical support to our utility clients and their customers.

In August 2012, Hurricane Sandy made landfall along the mid-Atlantic coast, causing approximately $65 million worth of damage. We rapidly deployed nearly 400 employees and restored power to the citizens of New Jersey.

The Keyport – Belford New 34.5kV Line project involved constructing a new transmission line spanning approximately 5.63 miles, with comprehensive substation, distribution, and transmission work. Riggs Distler served as the general contractor, overseeing all project aspects under one hat.

This project replaced 445 wood structures with steel monopoles along the Garden State Parkway, using helicopter construction techniques for 14 pole installations to rebuild the 69 kV line.

Riggs Distler provided turnkey services for a major New Jersey Landfill RNG Project, transforming landfill gas into pipeline-quality renewable natural gas.

We helped New Jersey build it’s first RNG plant that turns landfill gas into clean energy, using advanced filtration, tight teamwork, and two-shift construction to meet an aggressive schedule in limited space.

In 2017-2018, multiple Category 3+ struck Puerto Rico, damaging the electric power grid. Through quick mobilization and utilization of helicopters, we restored a portion of the island’s power supply.

This sustainable energy project delivered 35 miles of biogas and HDPE pipeline linking South Dakota dairy farms to the gas grid, converting captured methane into renewable natural gas.

Inside a century-old Philadelphia building, we constructed a reverse-osmosis plant producing 2,000 gallons of demineralized water per minute, installing new switchgears, two 480V motor control centers, and two 120/208V power panels.

Riggs Distler’s Underground Utility division was tasked with the installation of over 33,000 smart nodes in Maryland street lighting fixtures throughout 2023.

Riggs Distler was awarded the first US-based Tier 1 Contract for Secondary Steel for the South Fork Wind Farm.

Despite inheriting the project at 25% completion, we delivered a modern CHP steam plant generating 5.6 MW, recycling exhaust heat, and supplying 40% of campus electricity with improved efficiency.

In Fall 2024, Hurricanes Helene and Milton devastated the Southern U.S. Our electric crews mobilized across multiple states, restoring power and providing critical support to impacted communities and utilities.

In 2005, Hurricanes Katrina, Rita, and Wilma caused widespread damage to nearly 3 million homes in the Gulf Coast region. With our teams ensured safety and helped restore power to tens of thousands of homes of citizens.

Our Substation group completed the Texas Ave. 69kV Upgrade Project in 2023 in Lawrence Township, NJ. This award-winning project was a significant endeavor, with a comprehensive scope that included the installation of a variety of critical infrastructure components.

Our team engineered, procured, and constructed a 0.5 MW, 2 MWh battery storage facility in West Caldwell, integrating advanced batteries, inverters, transformers, and supporting electrical infrastructure.

We added a third transformer bank, plus circuit breakers, disconnect switches, a CTPT Combo metering unit, and a new control building in Mahopac, boosting capacity and resilience for 35,000 customers.
