Helping clean renewable energy flow freely

Interest in hydropower is growing, and CTLGroup has provided vital services to the industry for years.

Hydropower – electrical energy created from flowing water – is one of the oldest forms of energy production, and is the most widely-used renewable source of energy. Hydropower has several advantages over other forms of energy generation: minimal pollution; reduction of greenhouse gas emissions; low operations and maintenance costs; proven technology; and a low-cost source of "fuel" (water) renewal via rainfall and snow melting.

Because of its numerous advantages, as well as the push for clean energy and the relatively higher costs of other types of energy production, hydropower has made a comeback in the last few years. However, one challenge that newly constructed hydropower facilities face is significant capital expense. CTLGroup helps designers, engineers, contractors and owners in the pre-construction and construction phases to optimize design considerations and construction practices and therefore reduce development and construction costs.

We have extensive experience with issues facing all components of hydropower plants, including dams, powerhouses and penstocks. Whether we are developing innovative low-heat mixtures for efficient mass concrete placement in dams, developing thermal control plans to reduce the time of construction without compromising durability, conducting on-site nondestructive testing (NDT) to determine causes of structural damage, or performing petrographic examinations to examine material degradation , our experts are equipped to tackle the toughest challenges.

CTLGroup has provided services critical to new construction and rehabilitation of hydropower facilities, including:

  • Mass concrete consulting
  • Thermal modeling
  • Concrete mixture optimization
  • Development of high-performance mass concrete
  • Chemical and mortar testing
  • Heat of hydration testing
  • Condition and durability assessments
  • NDT
  • Petrographic analyses
  • Strength testing
  • Failure investigation
