Evals

All-in-one solution to rapidly evaluate hydropower sites.

Optimise the full potential of your hydropower site

Decisions about where to locate and how to optimise hydropower sites can be paralysed by seemingly infinite considerations and uncertainties. EVALS offers an all-in-one solution to confidently make decisions based on trusted and reliable data, the latest modelling technology and Tractebel’s deep engineering expertise.

 

For over 40 years, EVALS has been empowering engineers with the information and insights to rapidly evaluate hydropower sites and optimise their full potential. It’s the only solution on the market that simultaneously offers a decision and design support system for dimensioning, cost estimation and economic evaluation.

Benefits

SMARTER & FASTER

  • EVALS enables design teams to quickly identify, confirm and address challenges with project sites and layouts. The result is smarter engineering that’s more creative, cost-effective and sound for projects.

DIVERSE USE

  • EVALS can be used in a range of applications from master planning to pre-feasibility and feasibility studies. It’s the ideal solution for dimensioning, costing and economic evaluation of projects.

ALL-IN-ONE

  • Instead of piecing together information and insights from multiple and sometimes conflicting sources, EVALS offers an all-in-one solution powered by GIS and the latest in BIM, CSG and CAD technology.

Key Features

Powered by GIS

EVAL considers the environmental and social impacts locally and spatially, powered by Geographical Information Systems (GIS) technology. The software enables you to place and interlink more than 20 different hydropower elements in a spatial context from topography and hydrology to environmental protection. It applies specific algorithms and weighing functions to inform and optimise the design layout with the least impact.

Automation that improves performance

EVAL enables the automation of:

  • Dimensioning and the partial optimisation of principal project elements
  • Determination of project installed capacity and annual production
  • Calculation of project cost-components for all elements, total CAPEX and annual OPEX
  • Computation of the IRR, LCOE, net present value and cost-benefit ratio

Parameteric Design Approach

Design parameters are stored inside an engineering library where each parameter can be modified, and designs are simultaneously updated accordingly. The required hydraulic calculations for dimensioning of each element are performed such as flow profile along a spillway, water hammer, intake vortex depth, headloss, reservoir routing, and normal depth calculations. Constructive 3D Solid Modelling (CSG) technique is adopted for EVALS to calculate accurate bill of quantities and prepare potential integration with BIM and CAD.

Programmable Cost Functions

EVALS cost estimates are based on unit prices defined within a UCOST database.
The unit prices are the outputs of built-in programmable cost functions, so it’s easy to update UCOST to different regions. The UCOST includes cost lists for labour, equipment, construction material, and fuel, and programmed procedures that can be converted into aggregated compound rates.
