DLZ’s subsidiary in Costa Rica, DLZ Carbon, has extensive experience in hydropower engineering, ranging from initial site identification, pre-feasibility and feasibility studies, basic and detailed design, construction drawings, specifications, construction supervision, owner’s engineer of record, dam surveillance, and dam safety studies.
The experience dates back to 1996 and covers eight countries in the Central American and northern South American region: Costa Rica, Nicaragua, Panama, Honduras, Guatemala, Mexico, Guyana, and Colombia. Carbon Ingeniería has been involved in over 75 hydropower projects in the region, with a combined installed capacity of over 800 MW in basic studies and preliminary design and of over 600 MW in detailed design. These projects have been developed under the strict environmental regulations of the host countries and have incorporated the assessment of seismic risk and seismic-resistant design.
DLZ’s experience in India is extensive and we commissioned the first privately owned hydropower plant in India in the state of Maharashtra in 2001. DLZ has designed, built, owns, and operates seven small to medium-size hydropower plants in India through various subsidiaries totaling 73.5 MW. One project is a unique first-of-its-kind project which is located on the tailrace channel of the cooling water system of a large 1500 MW thermal power plant run by the Central Government of India. We have designed and installed hydropower plants with high head using Pelton or Francis turbines to lower head turbines using Kaplan turbines. Plants with high heads have been in challenging rugged terrain requiring substantial civil works including trench weirs for diverting the flow from the stream, desilting basins for removing sediment, open channels, and long tunnel sections for conveying the flow to forebays, penstocks, and powerhouses.
DLZ has conducted detailed investigations related to the feasibility of renovating existing hydropower facilities at several locations in the U.S. DLZ also looked at retrofitting the existing Grigg’s dam in Columbus, Ohio with a new hydropower facility. DLZ has extensive experience in the design and construction of dams and related facilities. Through our predecessor companies, DLZ has been involved in the design/ rehabilitation of virtually all of the dams in the midwestern United States. We have had significant dam-related projects with the US Army Corps of Engineers, the Miami Conservancy District, the Muskingum Watershed Conservancy District, and various state and local agencies.
