Small up to 10 MW

(20 MW Peru )

Mini up to 1 MW

Micro up to 100 kW

Pico up to 5 kW

Characteristics

Run of the river schemes

Decentralized power generation

Grid connected or isolated mini-grid

Plant operation with lower automation level

Often limited available data for detailed design

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

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
