Gas Transportation Infrastructure
Russia is the largest supplier of natural gas in the world market, therefore reliable and efficient gas transportation infrastructure plays crucial role in national gas industry. Power supply of strategic gas facilities requires greater attention to power sources reliability and quality. Harsh environmental conditions in some regions of Russia can obstruct power supply of gas transport system infrastructure.
BPC Engineering – the leading provider of power efficient solutions in distributed generation market – offers onsite power plants based on Capstone microturbines for the reliable and efficient power supply of gas transportation infrastructure.
- Gas pipelines linear parts
- Booster compressor stations
- In-line compressor stations
- Gas distribution stations
Capstone microturbine-based packaged power stations provide a reliable solution for power supply of gas pipelines
High reliability, integrated automation and remote control and monitoring capabilities make Capstone microturbine-based mini-power plants a perfect solution for power supply of strategically important facilities of gas transportation infrastructure including block valve stations, cathodic protection, and telemetry systems. These facilities do not consume much power – usually several dozens of kilowatts. In such projects Capstone microturbines can be used as a prime, backup, or combined power source.
Microturbine power plants meet the most stringent safety and environmental requirements and can operate at gas pipeline parts running through nature reserves. Extended maintenance intervals, small quantity of spare parts, and absence of oil and coolants ensure continuous unmanned operation of onsite microturbine power plants at extremely low operational and service costs.
To ensure reliable power supply of gas transportation facilities BPC Engineering manufactures ENEX packaged power plants based on Capstone microturbines. A standard ENEX power plant for gas pipelines includes one prime unit of required power output (10, 15, 30, or 65kW) and one standby unit. The prime unit runs on natural gas and the standby unit runs either on diesel or natural gas. This configuration enables redundant power supply with automatic system start in a case of gas supply shortage.
Capstone microturbines vs. alternative solutions at gas transportation facilities:
Capstone microturbines can be used for onsite power supply at other facilities of gas transportation infrastructure: gas boosting stations, line compressor stations, or gas distribution stations.
The projects completed by BPC Engineering proved the efficiency of Capstone microturbines for gas transportation facilities.
In the end of 2009 twelve packaged microturbine power plants were commissioned along the Dzuarikau – Tskhinval gas pipeline. This pipeline is the highest installation of its kind in the world passing 5 mounting ridges on its way. Since the highest point – the Kudarsky pass – is located at 3 148 m above sea level, the system reliability and long maintenance intervals were the key factors of choosing Capstone microturbines for operation in such remote areas. Each power plant comprises two Capstone C30 microturbines, one of which is prime and the other one is standby. The microturbines run on the pipeline natural gas.
Eleven more packaged microturbine power plants were installed along the 200-km long Okha (Sakhalin) – Komsomolsk-on-Amur gas pipeline. The customer imposed stringent requirements for generating equipment reliability and environmental performance since the gas pipeline passes through a nature conservation area in close proximity to the Amur River. Standby units of the power plants run on diesel allowing for uninterruptible power supply even in the case of unavailability of gas.BPC's packaged power plants based on Capstone microturbines also operate at various sites of Gazprom: the facilities of the Nord Stream gas pipeline, the Blue Stream pipeline, the Pochinki-Gryazovetz pipeline, the Bovanenkovo-Ukhta pipeline, Gazprom Transgas Stavropol gas distribution station, totaling in more than 200 gas turbines.
