Delivery of First New Generation GE Power HA.02 Gas Turbine

General Electric Power and Water have recently delivered the first HA.02 unit to the Exelon Wolf Hollow site in Granbury, Texas.   Groundbreaking for the new power generating station was held on July 9, 2015.  The new CCGT (combined-cycle gas turbine) will provide an additional 1,000 megawatts to the existing 704 megawatt natural gas power plant.  The new unit is to be one of the most environmentally friendly and efficient CCGTs in the state and nation. It utilizes GE Power’s most advanced gas turbine technology and an air cooling system, which eliminates the use of water to cool the unit.

Hi-Tek Manufacturing, Inc. worked to develop the manufacturing of several critical components for the HA.02 hot gas path engine section.  The components include stage 1 and stage 2 vanes, baffles, and near flow path seals, and were developed with an extremely fast track New Product Introduction (NPI).  Hi-Tek Manufacturing’s engineering, quality, and manufacturing team developed the processing of these critical hot gas path components in the shortest time frame in the company’s history.  Utilizing the latest developed technology in laser, CBN grinding, fast hole EDM machining, and in-house braze and heat treat was the key to Hi-Tek’s success.

“It was a collaborative effort,” stated Barry Nehls, Sales and Marketing Manager.  “The General Electric Power and Water need dates for qualified, finished components was critical to the engine assembly and test schedules. Working with the GE team from engineering, sourcing, quality, and production required constant detailed communication in order to achieve our common goals.”

The HA.02 gas turbine power generation turbine is the first of two to be installed at the Wolf Hollow facility.  An additional 1,000 megawatt CCGT is being constructed at Exelon’s existing Colorado Bend Generating Station in Wharton, Texas, approximately 60 miles outside of Houston.  Both sites are expected to achieve commercial operation in 2017.  Hi-Tek Manufacturing, Inc. is pleased to be a GE Power and Water global supply chain partner to provide manufactured components for this exciting new HA.02 engine program.

We’re Doing Something Right When it Comes to Quality!

At Hi-Tek Manufacturing, we take our business very seriously. Since 1980, we’ve been serving the gas turbine industries, offering conventional and non-conventional CNC specialty machining for Hot Gas Path Components.  We’re a Six Sigma based company, working to ISO, AS, and NADCAP Standards. We deliver the highest quality and most cost-effective solutions to aviation and land-based turbine manufacturers.

What makes Hi-Tek Manufacturing unique in our industry is our passion for quality, and the fact that we monitor and maintain quality control ourselves. We do not outsource the QC function; everything is done in house, using several quality tools. (Take a look at the “Quality” page on our website for more detailed information.)

One of the performance-driven metrics we use is “Total Monthly Defects” – see the chart posted here:

hi-tek 1-2013A “defect” is defined as any part non-conformance that requires disposition prior to shipping the part to our customer. Dispositions that may be included in this performance metric are rework, repair or scrap. The chart above reflects a Total Monthly Defects performance goal of 1% and the corresponding Hi-Tek Manufacturing actual performance for the 10-month period of April 2011 through January 2012.

Looking at our performance, we know we’re doing something right when it comes to quality! We’re avoiding non-conformances and we’re meeting our quality performance goals every day.  Our customers know they can count on high-level performance and exceptional quality when you work with Hi-Tek Manufacturing. We’ve got the QC function under control in house, and we wouldn’t have it any other way!
