BBA

Hydropower

The design of every hydropower facility is adapted to its particular environment. Consequently, each has its own technical challenges which require in-depth understanding and hydropower experience. For the past 35 years, owners, operators and developers have called upon BBA to deliver new hydro projects and to maintain, optimize and refurbish existing facilities. We work on hydropower facilities of all sizes, from a few megawatts up to several hundred megawatts of installed capacity, and provide full-package, water-to-wire engineering design solutions to the hydropower industry.

 

BBA holds extensive expertise in the hydropower sector along with vast knowledge of industry technologies, standards and best practices. Given our strong relationships with trusted contractors, manufacturers and financiers, BBA is a partner of choice for your existing or new hydro projects.

 

Project Development:

Facilitate, lead and support the development of major capital hydro projects (greenfield and brownfield), from project identification through to the planning, design, construction and commissioning phases.

 

Hydrology:

Watershed modeling for flood analysis and forecasting using digital topography and digital land use maps. Modeling of design storm events over a watershed to estimate probable maximum flood (PMF) and return period floods. Hydrological model development for energy modelling, project financial analysis and environmental impact assessment.

 

Structural Engineering:

Structural and hydraulic design of tunnels, concrete dams/weirs, spillways, intakes, canals, pipelines, penstocks and powerhouses.

 

Penstock/Pipeline Design:

Hydraulic and structural design of buried and surface penstocks. Alignment optimization for cut/fill material balance. Hydraulic optimization.

 

Powerhouse Design:

Sizing, specification and integration of turbines, generators, exciters and governors. Design of P&C systems, electrical and mechanical station services, instrumentation, energy management systems and telecommunications systems.

 

High- and Medium-Voltage Electrical Design:
