Orange Grove Energy earns VPP Star status

Over the last decade, CCJ’s best practices program has seen a dramatic uptick in entries pertaining to safety, a few for achieving VPP Star status. If you’re not familiar with the acronym VPP, Voluntary Protection Programs is an OSHA initiative that encourages private industry and federal agencies to prevent workplace injuries and illnesses through hazard prevention and control, worksite analysis, training, and cooperation between management and staff.

The certification process is arduous and can take a couple of years in some cases. Success depends to a great degree on the commitment of the personnel involved. It’s no mission for the faint of heart.

John Hutson, plant manager of Orange Grove Energy (OGE), a two-unit LM6000 peaking facility in Pala, Calif, shared some highlights of his plant’s journey to certification with the editors on a recent call. The flag-raising ceremony, well-attended by owner J-Power USA and operator NAES Corp executives (Fig 1) and plant personnel (Fig 2), took place a few weeks following the 2019 NAES Plant Managers Conference, September 17-19 (see following article).

Hutson recalled that he and Compliance Manager Ramiro Garcia attended a NAES Safe Conference in 2017 where CEO Bob Frishman asked all plants to consider pursuing VPP certification. It was clearly a benchmark for all NAES plants to strive toward in their safety culture. A few months later, J-Power USA CEO Mark Condon asked that all of his company’s plants be certified VPP Star.

Hutson and staff accepted the challenge with a desire to improve an already successful safety program while having OGE officially recognized as the elite organization all personnel believed it was.

Garcia served as the plant’s interface with Cal-OSHA, Palomar Energy (the VPP mentor facility), and the consultants engaged for the effort. Tony Moretto led his team of OMTs—including Al DeLuna, Erik Cherry, Gregg Stephens, and Paul Braemer—on making the O&M improvements that became evident as OGE worked through the process. Corporate support was provided by David Jackson, VP safety; Boggy Barnett, senior manager of safety; and Chris Trevino, project manager of safety.

OGE addressed and closed more than 300 safety issues and actions identified by plant staff, certified safety professionals, and Cal-OSHA inspectors—this at a plant with an enviable safety record in a company that promoted safety continually. The plant applied for Cal-OSHA VPP Star certification in August 2018; official certification came in August 2019.

Sixteen plants recognized for their best practices

One of the highlights of the mid-September NAES Plant Managers Conference, which focused on safety and operational excellence, was a session dedicated to best practices. Presentations were made by the plant managers from the four facilities earning Best of the Best recognition from CCJ: Dogwood Energy Facility, Edgewood Energy, Elwood Energy, and the Quail Run Energy Center. Another dozen generating plants powered by gas turbines received Best Practices Awards (Sidebar 1).

The NAES Plant Managers Conference is not your typical user meeting; it goes beyond technology into the staffing and training challenges facing plant managers, shares leadership and consensus-building know-how, and digs into HR and environmental initiatives that require a plant manager’s attention.

Technical presentations are of a more general nature than one typically finds at frame-specific user meetings. Titles of the vendor presentations in Sidebar 2 illustrate this point. Presentations by plant personnel are much the same, geared for an audience with diverse information needs. The presentations by plant managers in the best practices session, which showcased NAES’s experience with 7F, 501F, LM6000, and 7EA engines, offered ideas that could be adopted at most gas-turbine plants. Below are thumbnails of the Best of the Best Practices with accompanying links for greater detail.

Dogwood Energy Facility. To improve operational performance and enhance personnel safety, plant staff designed and implemented procedures and modifications to verify proper seating of gaskets for steam-drum doors and to eliminate the need for hot torqueing.

Edgewood Energy. Plant staff took an unconventional route to outage success by selecting multiple service providers to perform maintenance and field services which drastically reduced the cost of LM6000 repairs traditionally provided by one company.

Elwood Energy. Changes in the plant’s operating profile prompted management to develop and implement a comprehensive, long-term employee training and retention program to develop the next generation of multi-skill powerplant O&M technicians and supervisors.

Quail Run Energy Center. Excessive vibration in one of the site’s generator rotors caused by thermal sensitivity led plant staff and a vendor partner to conduct comprehensive inspection, testing, and repairs that resulted in a successful return to service within proper design parameters.

MHPS

As plants strive to reduce operating costs, respond to changing grid demands, and maximize revenue, digital upgrades from controls all the way to artificial intelligence will fuel their progress. Mitsubishi Hitachi Power Systems is responding to these challenges with its MHPS-TOMONI® plant solutions aimed at steadily progressing towards a smart powerplant capable of autonomous operation.

“Creating the Smart Power Plant of the Future” offers generation-asset owner/operators a roadmap to the digital future and a look at the digital solutions that will be implemented in what the company calls the “world’s first smart power plant” under construction at MHPS’ Takasago Machinery Works.

The smart powerplant is aware of neighboring plants, grid congestion, power markets, and weather forecasts and able to provide real-time insights and recommendations based on analytics to optimally support the grid and maximize revenue from energy and ancillary services markets.

J-series Americas recap. After installing the first J-series turbine in 2017, MHPS installed 11 more machines in 2018. Four 501JAC orders booked in 1Q/19 were split between Mexico and the US. In early July, J-Power USA ordered two 1 × 1 501JAC power trains for the nominal 1300-MW Jackson Generation Project in Elwood, Ill. A noteworthy feature of this plant will be its ability to operate at less than 25% of full load while remaining in emissions compliance. In October, Suncor Energy ordered two 501JAC engines and two HRSGs for a future cogeneration facility at the company’s Oil Sands Base Plant near Fort McMurray. Finally, PowerSouth ordered a 640-MW combined cycle, powered by a 501JAC engine, for its Lowman Energy Center in Leroy, Ala, to replace ageing coal-fired units.

Paul Tucker, president of Houston-based TBS Manufacturing/FIRST Consulting & Inspection Services, called to say his company now manufactures accessory couplings for GE Frame 3, 5, 6, and 7 engines, as well as for some Westinghouse and Siemens gas turbines. Product includes the shaft as well as the external shaft hub with an external spline as well as the coupling hub itself, which has an internal spline. Companion service offering includes repairs to shafts/couplings fit for further use.

Tucker, one of the industry’s pre-eminent turbine mechanics, also spoke to the availability of custom 7F and 7EA inner and outer crossfire tubes using a new manufacturing process that is said to offer longer life than the traditional rolled-plate/seam-welded design. TBS’s crossfire tubes are made from solid bar stock (L-605) to avoid the typical out-of-round condition near the end of life.
