Improve Turbine Flexibility & Reliability with Fuel-System Modifications

Category: Uncategorized


With the instability of oil prices, it is mission critical to control operating costs. Put your power generation needs in the hands of power generation experts, make sure you have 100% fuel availability.

Gas turbines are one of the leading sources of power generation in the United States, making their ability to produce consistent power crucial at all times. While natural gas is the most popular fuel due to its overall abundance, cost-effectiveness, and environmentally friendly status with modern advanced combustion systems, it shouldn’t be the only fuel source. Unpredictable global political and economic conditions, extreme weather conditions, as well as new discoveries in oil and gas exploration, can skew any forecast on fuel pricing and availability. By adding the capability to burn multiple fuel sources, gas turbine users can be prepared to handle these unexpected changes that arise. Not only can this increase their value in terms of improved versatility, but it will also ensure their availability to produce power under any economic circumstance.

A recent case where the importance of fuel flexibility has been needed are severe winters that have caught gas turbine users in gas curtailments. The winter of 2013-14 caused record snowfall, ice storms and arctic temperatures throughout the country and gas curtailment was commonplace for gas turbine operators.  One of the largest situations in recent years occurred in February 2011, where an arctic cold front descended on the Southwest region and brought temperatures below freezing and sustained wind gusts up to 30 mph. The area hit was extensive, complicating efforts to obtain power and natural gas from neighboring regions. Local distribution companies passed extensive curtailments of service during the event, where they interrupted gas service to more than 50,000 customers in New Mexico, Arizona and Texas. During this time the surrounding gas production basins had decreased production due to low market prices and according to the Federal Energy Regulatory Commission, an estimated 14.8 BCF of natural gas production was lost, further complicating the effects of the extreme winter.

In any situation when natural gas costs are high or supply is hard to obtain, users that have the capability to burn alternative fuels, such as distillate liquid fuel, are able to continue to generate uninterrupted power.  And as in any economic situation when the supply of power is low (as during gas curtailments) the price of power rises. The importance of adding another fuel source to gas turbines has been proven to be vital to increasing reliability of power. Now, several utilities are making fuel flexibility a contractual requirement for their non-utility generators desiring contracts within the utility operating area.

With over 30 years of experience, Turbine Technology Services Corporation (TTS) has performed numerous fuel conversions to many different types of gas turbines and can provide the fuel flexibility that most power systems need.
