Distributed Power & Data Centers

A projected 217 GW increase in U.S. distributed energy resource capacity through 2028 (Martucci, 2024) necessitates greater investment in the grid and storage. NPL Construction supports distributed power generation, renewable natural gas (RNG), industrial energy improvements, and data center construction. Our teams deliver comprehensive scopes, resulting in resilient assets that integrate with existing utility systems and meet evolving load profiles.

Emergency Response & Storm Restoration

The average annual number of power outages caused by adverse weather has increased by almost 80% since 2011 (Grid Deployment Office, 2023). When severe weather strikes, mobilization speed determines community impact. We maintain 24/7 readiness and large‑scale surge capacity to clear debris and repair utility assets. Our emergency storm restoration command structure, prepositioned asset fleets, and our certified rebuild crews help utilities shorten outage durations.

Fabrication Shop

With 22,000 sq ft of fabrication space to support your energy infrastructure construction, NPL Construction saves time and costs. We build pipes, compressor stations, vaults, and drips—across carbon, stainless, and specialty alloys to specifications. Other in-house fabrication capabilities include ASME/API‑qualified welding, hydro and pressure testing, X-ray services, and coatings by NACE‑certified personnel.

Natural Gas Infrastructure

From neighborhood distribution to transmission, we self‑perform energy infrastructure construction across design, permitting, materials management, construction, traffic control, testing, and restoration. In the construction phase, our natural gas services include excavating and core boring, trenchless technologies, installing polyethylene and steel mains, regulator and compressor stations, and gas maintenance and repair.

Pre- and Post-Construction

We provide end-to-end turnkey solutions. Pre-construction services include engineering, permitting, training, construction management, and material management. Construction involves gas maintenance and repair, trenchless technologies, regulator station work, and O/M services. Post-construction services include relights, inspection/QC, landscape restoration, GPS telematics, and record keeping.

Underground Infrastructure

Our large and national directional drill fleet executes complex underground scopes. We handle joint trench corridors, large‑diameter bores, road, rail, water crossings, vaults, and urban replacements—using HDD and other trenchless methods to reduce surface disruption.

Featured Projects

Data Center Alley – Turnkey Fiber Delivery 

Amidst the growth of AI and cryptocurrency in one of the nation’s most active data center hubs, NPL Construction installed 16 miles of fiber conduit using a blended approach—open-cut construction and horizontal directional drilling (HDD)—while protecting sensitive natural and cultural resources.

  • Scale: 16 miles of fiber conduit and six HDD maxi rigs with 600,000-pound capacity to execute long, complex crossings with varying depths.
  • Challenges handled: HDD under the Monocacy River, traversed ecologically sensitive areas, and routed around historically significant sites.
  • Innovation: Used specialized HDD tooling and deployed disciplined fluid reclaim and restoration practices to minimize surface disturbance and environmental impact.
  • ROI: Zero safety or environmental incidents and restoration to original or better condition.

Industries Served

We serve investor‑owned and municipal natural gas distribution companies, industrial energy users, and the data communications sector. In these end markets, our proactive communication, cost transparency, and ability to surge resources for seasonal peaks and storm events differentiates us.
