Welcome to Komi

Dresser-Rand KG2 turbines provide on-site electrical power for one of Russia’s largest oil producers.

The climate is often severe, with long, cold winters and short, cool summers. Average temperatures in January hover just above zero degrees Fahrenheit (-18 degrees Celsius).

Welcome to Komi.

One of the northernmost republics of European Russia, Komi is located approximately 650 miles (1,046 km) north of Moscow and less than 400 miles (644 km) south of the Arctic Circle. It’s among the largest oil and gas producing regions in European Russia and one of the country’s top 10 producers.

One of the area’s oldest fields, Lekkerskoje (Lekker), is situated near the city of Usinks, founded in 1966 as an oil and gas production center settlement. Since the Lekker deposit is in a remote location, there are no external electric power networks. Because of this, it’s critical to maintain an uninterrupted power supply.

Initially, diesel power stations were used to provide power to the local infrastructure. Russia’s second largest oil producer, Lukoil-Komi (a branch of Lukoil), decided to upgrade its power generation facilities at Lekker. After careful consideration of the proposals, company managers opted to purchase and install four 1.8 MW Dresser-Rand KG2 turbine generator sets and auxiliary equipment. Zvezda-Energetika, a key player in the Russian power generation industry, was selected as the local packager for the four skid-mounted KG2 turbine generator sets.

Sustainable Power Stations
Designed to meet demanding emissions regulations, the KG2 gas turbine is ideally suited for continuous power generation on- and offshore, emergency and stand-by power supply, and as an indirectly-fired option for CO2-neutral biomass plants. Because of its simple, low-maintenance design, high reliability, and operational experience, the KG2 turbine generator package is a preferred solution for these types of applications. The wide fuel range also enables operation on extremely low heating value fuels, landfill gas and associated gas from crude oil production.

One of Lukoil-Komi’s key variables in choosing the KG2 is that it can accept a wide variety of fuels, ranging from pipeline quality natural gas to low heating value gas. According to Russian Federation law, flaring of gas is subject to heavy fines. The Dresser-Rand power station solved this problem by producing electricity on-site from available resources, which prevented flaring. These types of power stations are specifically engineered for fuel flexibility and sustainability, so that the gas can be used as an energy resource instead of being wasted through venting or flaring. It’s not only efficient, but better for the environment, too.

A History of Reliable Operation
The KG2 has proven itself in a variety of installations, with more than 1,200 units clocking more than 25 million operating hours with 99 percent availability. Some engines have been running more than 245,000 continuous hours and have achieved a lifetime of more than 30 years of run time.

The unit requires minimal maintenance, important in a region with limited accessibility. In addition, the package is suited to the harsh northern conditions because the container is constructed in such a way that all maintenance can be performed from the inside. Some of the competing have tight containers and maintenance is possible only through open doors or hatches.

Cogeneration – an Added Benefit
Another advantage of the versatile KG2 turbine is its combined heat and power (CHP), or cogeneration capability. CHP systems facilitate electricity production and provide useful heat at a very high efficiency. The turbines at Lekker operate with a heat recovery system, so they not only produce electric power but provide heat energy as well.
