Municipal Projects
Ames, IowaLDB has successfully completed over a dozen projects for the city of Ames, Iowa. Projects included electric utility engineering services and the design of a 65,000 kW unit addition to their Municipal Plant No. 2. Refuse derived fuel (RDF) is used in conjunction with other fuels to fire the boiler and is conveyed to the unit through a pneumatic transport system.
Colorado Springs, Colorado
LDB and Colorado Springs Utilities (CSU) have enjoyed a working relationship spanning 68 years and the successful completion of over 77 projects. Projects included the design of three power plants with eight steam electric generating units. The design of the 200,000 kW steam generating unit at the Nixon Plant included the development of a new plant site. The Denver Post contained an editorial complimenting Colorado Springs Utilities for their use of the 5600 acre plant site, which also serves as a wildlife refuge.
Garland, TexasGarland Power & Light (GPL) has retained LDB in the design of more than 31 projects which included a 76,000 kW combustion turbine, a substation modification that included a 100 MVA transformer and two 138 kV overhead lines. Using a specifically tailored design - bid - build project, LDB helped GPL save more than 5 million over a design - build offer for the same unit. Plant improvement projects included piping stress analyses and high pressure piping modifications for a 150,000 kW steam generating unit. Protective relaying was also designed for their Olinger Plant.
Higginsville, MissouriLDB provided the design for the installation of a combustion turbine for the Higginsville Electric Department (HED). This project included the addition of three distribution system circuit breakers and underground substation feeders at the Higginsville West Substation. LDB helped the HED develop an agreement with a neighboring utility which covered the debt service payments annually and installation of the unit at near zero net cost. The project also included the planning and design of a new substation and 69 kV line to provide two ties to Kansas City Power & Light. A new digital control system (DCS) was installed to control the combustion turbine, 69 kV tie and substation and existing diesel generators.
Manitowoc Public Utilities, WisconsinSince 1985 LDB has successfully completed over 84 projects for Manitowoc Public Utilities (MPU). Studies have been conducted of steam supply, steam distribution, cost allocation and revenue requirements. Power Plant design projects have included MPU’s first circulating fluidized bed (CFB) boiler which was the first CFB to be built in the State of Wisconsin. The MPU’s second CFB boiler and 63,400 kW turbine generator, also designed by LDB, is a cogeneration unit with automatic extraction to export steam to the MPU steam distribution system and is designed to utilize opportunity fuels.
Sikeston, MissouriLDB has provided services to the Board of Municipal Utilities (BMU) on numerous occasions relating to the preparation of an electric system review study, 290 MVA transformer replacement, substation and distribution system improvements and relay system upgrades.

Baldwin City, KansasLDB has successfully completed a number of projects for Baldwin City, Kansas. Projects include a new 6,330 kW diesel engine plant at a new site. The plant consists of two engine generator sets with space provided for a third unit. Other projects have included substation improvements, black start capability and spill prevention control, countermeasure (SPCC) plans & environmental regulation compliance.
Columbia, Missouri
LDB provided the design of two units at the Municipal Power Plant. Recent projects included a heating boiler for the Power Plant, a comprehensive condition assessment of the Power Plant, arc flash studies, relay installations and boiler modeling.
Grand Island, NebraskaSince first serving Grand Island Utilities Department (GIUD) in 1951, LDB has completed the design of 70 projects which include two new plants, Burdick Station and Platte Station with six generating units. LDB also designed major portions of the 115 kV subtransmission system, as well as the 13.8 kV distribution system. Each plant was designed with a 115 kV breaker-and-a half substation. The Platte Station 100,000 kW PRB pulverized coal fired unit has demonstrated a high degree of reliability. During one year this unit was the 7th lowest power cost producer of any power plant in the USA.
Independence, MissouriServices have included the preparation of studies, reports and a grant application for Independence Power & Light (IPL). LDB prepared the report which established the need for a new power plant site to be located on Truman Road. LDB has designed cooling tower replacements, water treatment and generator protection at the Blue Valley Power Plant.
Marquette Board of Light & Power, MichiganLDB has successfully completed over forty projects for Marquette Board of Light & Power (MBLP) since 1963. Designs have included all three steam units at the Shiras Power Plant and a combustion turbine. The plant includes a lake-side dock for berthing lake steamers which can directly unload coal onto the plant coal storage area. Shiras is equipped with a dry scrubber and was one of the lowest NOx and SO₂ emitting coal fired plants in the United States when the unit went in service. Other projects include substation and transmission lines.
Springfield, IllinoisLDB has provided engineering services to City Water, Light & Power (CWLP). Projects have included studies and designs for boiler dislagging, boiler feed pumps and scrubber auxiliaries for Dallman Power Station.
Springfield, MissouriLDB has provided services to City Utilities on numerous occasions. Assignments have included the design of the reconstruction of the 450,000 pph boiler, analysis of steam lines, Asian clam study, precipitator test at the James River Plant and a coal handling study at the Southwest Plant.

Bryan, TexasLDB and Bryan Texas Utilities (BTU) have a relationship which spans 62 years and the completion of over 68 projects. Projects include four steam electric generating units and one combustion turbine. The new Dansby plant site was developed and a 110,000 kW unit was placed in service. Other system improvements include four new substations, 22 miles of electrical transmission lines and a supervisory control and data acquisition (SCADA) system.
Falls City, NebraskaLDB prepared a power supply study followed by a feasibility study for Falls City, Nebraska. Design of a dual fuel diesel generating unit to replace aging electric generating capacity of the City’s electrical system has recently been completed.
Fremont, Nebraska
FDU was an initial client served by LDB when the firm was founded in 1948. Continuity of service in the intervening period has resulted in the successful completion of over 98 projects. Projects have included studies and designs for their water system, four steam power plant additions including the development of the Lon D. Wright plant site. Electrical distribution design includes seven substations, a subtransmission loop, supervisory control and data acquisition system (SCADA), relay system evaluation, studies of power supply, arc flash, Power Plant condition assessments, energy assessments and cooling tower fill replacement.
Greenville, TexasLDB has successfully completed over 20 projects for Greenville Electric Utility Services (GEUS). Projects at the power plant include water supply, waste water, auxiliary system improvements, breaker upgrades, substation circuit switcher improvements and a spill prevention control & countermeasure (SPCC) plan.
