Guam Power Authority (GPA) procured a 198 MW Ukudu combined cycle power plant on an IPP basis. The plant is expected to enter commercial operation in third quarter of 2025 and will initially operate on Ultra Low Sulfur Diesel. GPA intends to develop an LNG terminal to convert the Ukudu plant to operate on natural gas. K&M was retained as a lead consultant to assist GPA in conducting LNG terminal technical and commercial feasibility analysis, and, if proven feasible, to assist in procurement of the LNG terminal and negotiating as gas supply agreement.

Currently, K&M works on the Phase 1 of the project, which includes such tasks as estimating the LNG demand, analyzing source and delivery options, selecting the preferred site and configuration for the LNG terminal and developing terminal conceptual design and cost estimate. The scope of work also includes analysis of the possible business models, financial analysis, determining project feasibility and developing recommendations on whether to proceed with procurement of the LNG terminal. If GPA decides to proceed, K&M will assist GPA in procurement of the LNG terminal and LNG, negotiating a gas supply agreement, and overseeing work during the LNG terminal implementation.

Sixth Street engaged K&M for a technical due diligence review of a new 940 MW natural gas-fired combined cycle electric generating facility in the Village of Lordstown, Trumbull County, OH. The project will feature a 2×1 configuration, employing two Siemens Energy SGT6-8000H 1.6 combustion turbine-generator units (CTGs), two Nooter/Eriksen heat recovery steam generators (HRSGs), and one Siemens steam turbine generator (STG). The facility, collectively known as the Power Island Equipment (PIE), may utilize Vogt or Siemens HTT HRSGs. Additionally, the project will incorporate supplemental firing and evaporative cooling for enhanced power output in specific conditions.

K&M conducted a technical due diligence review, focusing on the Independent Engineer’s report, EPC and O&M contracts, and financial model assumptions. Following the review, K&M prepared a memo identifying project risks and recommending adjustments to the financial model assumptions.

K&M was engaged by DOE to perform a comprehensive industry and literature review of advanced coal combustion and utilization technologies, specifically circulating fluidized-bed (CFB) combustion units currently operating in the United States. K&M’s technical analysis provided a practical composite of summaries of U.S.-developed CFB systems based on such variables as fuel ash loading, size and steam flows. The report included CFB’s attributes, potential markets, a compilation of capital and operating costs in the United States as well as graphic displays

K&M was engaged by US DOE to assess the potential use of low quality/low cost alternatives to bituminous coal-based coal water slurry in heat engines already modified to burn such fuels. The successful development of these new technology prompted further research to determine the suitability of eight specific alternative low quality/low cost fuels. K&M also assessed the cost of production, availability and potential commercial success of low quality fuels, quality requirements vs. conventional heat engine fuels, and the state of current technology.

K&M was engaged by US DOE to survey technologies currently being used to horizontally drill for oil or gas using air instead of mud as the drilling fluid. The study identified areas where further developments in high-angle drilling with air might be most effective. It gave an overview of the current status of research efforts and industry perception of air drilling technology. The K&M survey also included techniques based on drilling horizontal wells with muds, a brief background in conventional horizontal drilling, and studies of individual wells.

K&M was engaged by US DOE to, along with its subcontractors, develop the conceptual design for the Externally-Fired Combined Cycle (EFCC) 7 MWe Demonstration Project at Dupont’s Waynesboro, Virginia facility. K&M assessed the technical feasibility of repowering the existing steam turbine-generator with an indirect-fired combined cycle system, as well as coordinated the efforts required to prepare a conceptual/preliminary design, including budgetary cost estimate and implementing schedule.

K&M was engaged by US DOE to assess the effects of erosion and corrosion on gas turbines and evaluate quantities of particulates, trace elements and other pollutants present in gas turbine exhaust. K&M also reviewed specifications for allowable trace metal contaminant levels in feed coal being developed by major turbine manufacturers to meet proposed new federal regulations. A sophisticated theoretical analysis was completed in the absence of experimental data to determine acceptable levels of contaminants. K&M’s work also included estimated economics of power generation via the three gasifier types, based on comparable cost of electricity calculation method supplied by METC.

K&M was engaged by the US DOE to analyze and interpret results of field studies, research and testing conducted on behalf of METC’s Clean Coal Technology Program to support development of commercially viable solid waste disposal technologies for utilization and management of residues generated from advanced coal technologies. This multi-faceted task addressed the environmental, health and safety aspects of project testing procedures and results, operating procedures, documentation requirements, and contractor surveys. K&M prepared assessments and recommendations for implementing strategies to maximize technology transfer to the utility and regulatory sectors. K&M also reviewed economic viability and market assessments for solid waste utilization.

The Nucal Station was the world’s first and largest utility-scale CFB facility, and the first application of this technology in the United States. K&M was engaged by DOE to perform a comprehensive evaluation of the technical progress relative to meeting project objectives, with particular emphasis on status of the test plan. K&M identified key test results, findings, and potential problem areas, compared test results with the original test plan, and reviewed variations. K&M also developed an independent test plan to assess the remainder of the testing for the facility.

K&M was engaged by US DOE to evaluate the potential performance and economics of membrane technologies for high temperature gas separations in three gasification system schemes. A systems approach using computer modeling compared the performance of these new technologies with baseline performance of existing processes. The new membrane-based separation technologies considered include those whose process steps include separation of H2 and CO2 gases, removal of contaminant gases such as H2S and NH3 and those that deal with other contaminates as indicated in the Clean Air Act of 1990. Research focused on ceramic, glass and metal membranes, with particular emphasis on flux and separation factors achieved by various types of membranes at moderate and high temperatures.
