HISTORY

Historical Descriptiptive Information

Dunlap (TP-l) Hydroelectric Powerplant is about 2 miles below Tp·1 Dam (Lake Dunlap) on the Guadalupe Aiver and 7 miles northwest of Seguin, Guadalupe County.

Ownership and History of Development

 The project is one of six hydroelectric powerplants that are owned and operated by the Guadalupe-Blanco River Authority on the Guadalupe River. These powerplants are Dunlap (TP-l), McOueeney (TP-3), Seguin (TP·41, Nolte (TP·5), H-4 Dam, and H·5 Dam.

The powerplants were authorized by the following water rights from the State Board of Water Engineers: Permit No. 21 (Application No. 21), dated July 25, 1914, which granted an appropriation not to exceed 1,300 cfs, continuously, from the Guadalupe River, for the purpose of hydroelectric power development, to the Guadalupe Water Power Company (now owned by the Guadalupe-Blanco River Authority); and Permit No. 1096 (Application No. 1163), dated June 12, 1929, which granted an appropriation not to exceed 941,200 acre·feet of water per annum for power development purposes to the Hunt Development Company (now owned by the Guadalupe-Blanco River Authority). Construction of TP-l Dam began in 1927 and was completed in 1928, with impoundment of water and generation of power beginning at that time.

The output from this and the other five plants is sold to Central Power and Light Company and delivered through necessary switches and transformers to the high voltage transmission system supplying power to the area. At the end of December 1967, this plant was in the process of conversion to complete automatic opera· tion. The control center and necessary equipment are located in the office building of the Guadalupe-Blanco River Authority in Seguin.

Two 1,800 kw generating units at Dunlap (TP.1) Hydroelectric Powerplant provide a total generating capacity of 3,600 kw. Each of the two vertical generators is a 1,800 kw, 3 phase, 60 cycle, 2,400 volt, 180 rpm unit with a direct connected exciter. The generators and control equipment were furnished by the General Electric Company. 

Each of the two vertical turbines is a James Leffel and Company, 180 rpm, Francis type, with a capacity of 2,800 hp at 46.0·foot head. At this plant, each turbine is installed in an open wheelpit equipped with trashracks and headgates. Water discharged from the Dunlap Hydroelectric Powerplant is subsequently used by downstream plants, each plant storing water during low-flow periods for use during the time of peak power requirements. Maximum water discharge per unit at full load is 625 cfs.

An intake structure at the dam controls flow to the 2-mile long diversion canal to the powerhouse. Additional powcrhead is gained by the use of this canal. Forebay water level is at elevation 573 feet above msl. Tailwater elevation is 527 feet above msl. Gross head for the turbine is 46 feet. One-foot high flashboards provide additional head. The Dunlap powerplant was a run-of-river plant until June 16, 1964, when storage began in Canyon Reservoir near New Braunfels. After that date, the flow of the river was partly regulated by releases from Canyon Reservoir. Water releases from Lake Dunlap are oontrolled by the operation of the turbines while generating power, and by spillway gates.

Permit No. 21 (Application No. 21), dated July 25. 1914, which granted an appropriation to the Guadalupe Water Power Company (now owned by the GuadalupeBlanco River Authority) of not more than 1,300 cfs, Continuously, from the Guadalupe River, for hydroelectric power development; and Permit No. 1096 (Application No. 11631, dated June 12, 1929, which granted an appropriation to the Hunt Development Company (now owned by the Guadalupe-Blanco River Authority) of not more than 941,200 acre-feet of waterper annum for hydroelectric power development.

Construction began early in 1927 and was com· pleted in November 1927, with impoundment of water and generation of power beginning at that time.The output from this and the other five plants is sold to Central Power and Ught Company and delivered through necessary switches and transformers to the high voltage transmission system supplying power to the area.

At the end of December 1967, this plant was inthe process of conversion to complete automatic operation. The control center and necessary equipment are located at the office building of the Guadalupe-BlancoRiver Authority in Seguin.  Two 1,240 kw generating units at Nolte (TP-5) Hydroelectric Powerplant provide a total capacity of 2,480 kw

Each of the two vertical generators is a 1,240 kw, 3 phase, 60 cycle, 2,400 volt, 150 rpm unit with a direct connected exciter. The generators and control equipment were furnished by the General Electric Company. Each of the two vertical turbines is a James Leffel and Company, 150 rpm, Francis type, with a capacity of 1,950 hp at 27.0-foot head. Each unit is controlled by a Woodward governor. At this plant, each turbine is installed in an open wheelpit equipped with trashracks and headgates.

Water releases from Lake Nolte are controlled by the operation of the turbines while generating power, and by spillway gates. Water discharged from upstream plants may be stored during periods when the power load is light and used during the time of peak power requirements. Maximum water discharge per unit at full load is 650 cfs. 

An intake structure on the left bank of the dam oontrols flow to the 1.5-mile long diversion canal to the powerhouse. Additional power head is gained by the use of this canal.
