Provided herein are systems and methods for utilizing a natural gas letdown generator at a natural gas regulating station. The system utilizes the gas letdown generator to generate electricity by converting high pressure inlet gas to low pressure outlet gas, which in turn creates low temperature outlet gas. Electricity generated can power a data center. Heat may be transferred, using a heat exchanger, from dielectric fluid of the data center to the natural gas prior to entering the gas letdown generator. Heat may be further transferred, using a second heat exchanger, from the dielectric fluid to the natural gas at the output of the gas letdown generator. The heat exchange may substantially cool the dielectric fluid for transmission to the data center and may heat the low temperature outlet gas for transmission to an end user.
