Data Centers
The System: From Storage to Power
A CPC fuel assurance system for a behind-the-meter powered data center or distributed power application is a turnkey, automated facility designed to deliver pipeline-quality natural gas on demand, independently of grid or pipeline conditions. The system is fully instrumented, black-start capable, and sized for multi-day autonomous operation.
The facility comprises five integrated subsystems, each designed for autonomous operation without grid or pipeline dependency:
| 1 | LNG Delivery | LNG liquefied on-site during non-peak season, or trucked to site via standard cryogenic transport with 2–4 truck unloading bays. |
| 2 | Full-Containment Storage Tank | Prestressed concrete outer wall with a 9% nickel steel inner tank. Sizes ranging from 2–50 MM gallons (0.15 Bcf to 4+ Bcf). |
| 3 | In-Tank Pumps & Send-Out | Submerged cryogenic pumps deliver LNG at required flow. BOG compressors capture boil-off gas for reuse. |
| 4 | Vaporization (N+1 Configuration) | Ambient-air or fan-assisted vaporizers (2×100% or 3×50%) convert LNG to pipeline-quality gas at required design pressure. From cold standby to full sendout in under 7 minutes, well within the bridging capability of a BESS system. |
| 5 | Gas-to-Power Generation | Regasified natural gas delivered at specified pressure directly to reciprocating engines, turbines, or fuel-cell systems. |
Reliability by Design: N+1 Vaporization
Vaporization systems are configured in a 2×100% or 3×50% (N+1) arrangement as standard. In either configuration, the facility operates at full send-out capacity with one vaporizer offline for maintenance or in a fault condition.
Simple, Proven Technology
Ambient-air and fan-assisted vaporizers have no combustion, no moving parts in the gas stream, and require minimal operator intervention.
OEM Support at Commissioning
CPC brings the vaporizer OEM to the commissioning process to ensure facility operators are fully trained to specification.
Warehouse Spare Option
Where the owner requires maximum resilience, a pre-positioned spare vaporizer can be included in the EPC scope — reducing any repair scenario to a scheduled swap rather than an extended outage.
Operator Training
All facility personnel are trained as part of CPC's commissioning handover package. The system is designed to be operated by the facility's existing O&M staff.
The Data Center Application: Physical Fuel Assurance
The standard "firm" gas contract does not provide the reliability that hyperscale data centers and AI compute campuses require. Firm is a contract term. It is not a physics term.
Firm contracts are subject to force majeure curtailment. Pipeline and grid constraints routinely override contractual firm commitments during extreme events — exactly the conditions under which data center operators cannot afford an interruption.
Physical Assurance
On-site LNG storage replaces contractual assurance with physical assurance: molecules on site, inside the fence, and available on demand.
Multi-Day Autonomous Operation
A facility sized to the power plant's fuel consumption provides days to weeks of ride-through — far beyond diesel or virtual pipeline solutions.
No Winterization Risk
LNG is inherently cryogenic. It does not freeze. LNG systems are not subject to the diesel freeze failures that affect large-scale backup generation in extreme cold events.
Cleaner and More Reliable than Diesel
LNG vaporizes to the same gas your engines already burn. No fuel switching. No combustion variability. No particulates. No degradation in storage. Cleaner than diesel on every metric that matters over extended run times.
Modular and Scalable
CPC's modular construction approach scales with facility growth — additional tank capacity can be added as a campus expands. The technology also scales broadly by project size: from a 1.5 MM gallon tank providing 2.5 days of full-curtailment ride-through for a 300 MW facility, up to a 24 MM gallon tank providing 10 days of autonomous operation for a 1 GW campus — and anywhere in between.
Why Choose CPC?
Proprietary Sliding Base Technology
Our sliding-base precast concrete outer wall is the only full-containment system that maintains vapor tightness independent of upset conditions; a documented engineering advantage over every LNG tank competitor.
50-Year Design Life
CPC's prestressed concrete systems are engineered for 50+ year service lives. Our Philadelphia Gas Works tanks have been in continuous LNG operation since 1974; over 50 years of uninterrupted service.
Full EPC Accountability
One contract, one team, one point of responsibility: from ground-breaking through first gas. We manage engineering interfaces, fabrication sequencing, regulatory submissions, and commissioning.
Financial Strength & Field Resources
CPC is a financially stable, well-capitalized company with the bonding capacity and balance sheet to support large-scale infrastructure projects. As an affiliate of the Cashman group of companies, CPC has direct access to shared resources across the organization, including field management, skilled-trades labor, heavy construction equipment, material procurement, and project controls. This integrated platform allows CPC to self-perform critical work and maintain schedule certainty on every project we deliver.
