Opportunities and constraints
Excerpt of 100 potential hydropower projects (1-100 MW)
Source: Atlas del potencial hidroeléctrico del Perú, 2011
Opportunities and constraints
Hydropower tradition in Peru Large Hydropower > 50% of total power generation in 2011
Small Hydropower is still dormant ~1%
Great hydropower potential (Small HP > 2000 MW)
European Union – Free Trade Agreement
Standardized Processes – Continuous Tenders
Atlas for Hydropower Potential in Peru
Growing economy and growing energy demand
Opportunities and constraints
A successful project
combines…
…ensure coverage of all
aspects and include
partners who supplement
your expertise
Importance of reliable partners and quality products
