Global Small Hydro Power Market Analysis to 2020 - Installed Capacity, Generation, Investment Trends

Hydropower is the Most Popular Source of Electricity Generation Across the World

Hydropower is the largest renewable source of power generation and currently accounts for about 20% of the world's total electricity supply. The world's hydropower installed capacity increased from 695.8GW (Gigawatts) in 2001 to 888.8GW in 2009, registering a Compound Annual Growth Rate (CAGR) of 3.1%. Since hydropower is a mature technology, it has witnessed a modest growth rate. Even though fossil fuels dominate electricity generation across the world, more than 60 countries use hydropower for meeting more than half of their electricity needs. The technology is the most popular renewable source of electricity generation as for various reasons, which include its ability to instantaneously respond to changing electricity demand, water management and flood control.

Small and mini hydropower generation plants have shorter gestation period. Large hydropower plants usually have a gestation period of about seven years, whereas it is about two to five years for smaller plants. Additionally, small and mini hydro gives a higher return on investment due to the low capital investment and operational and maintenance costs. Small and mini hydropower plants are easier to construct and commission due to simpler designs, thus keeping the costs down.

Small and mini hydro facilitates community participation and capitalizes on local skills for plant construction. Large hydropower plants require rigorous surveys, investigations and designs, which are not necessary for constructing a small and mini hydro plant. In addition to the above, construction of a small hydropower plant does not disturb the local habitat as is the case with large hydropower plants. Small hydropower installation does not involve the building of large dams and reservoirs and thus does not lead to the problems of deforestation, submergence and rehabilitation. Furthermore, it does not require a large land area and thus can be constructed in areas with small streams of water and small to medium rivers.

Annual installed capacity surged during 2004 mainly due to rise in new installations in China. Given the advantages of generating electricity from small hydropower coupled with rising interest in the sector has led to increased government support policies which will derive installations in many countries in the years to come. Cumulative installed capacity of small hydropower is expected to reach 140GW in 2015 and 201GW in 2020.

Global energy demand is rising fast, especially in developing countries, due to an increase in populations and industrialization. In order to meet this demand, it has become necessary to explore renewable energy sources, as conventional sources have become expensive due to the depleting supply. Small hydro provides an excellent and abundant source for power generation and does not have any fuel costs as it uses water; it emerges as one of the most promising solutions for ensuring a reliable and affordable energy supply in the long term.

You haven't installed a tile mount that is easier to install than the Solar Tile Mount manufactured by TRA Snow and Sun. Solar Tile Mount is used on all tile roof profiles: flat, mid, and high. It is made in the USA of aluminum alloy for strength and excellent corrosion resistance. Solar Tile Mount is built to allow more ease in installation with more rise from the tile surface to the rail for better air flow below panels. The adjustable base is longer than most allowing attachment 6" to the left or right to have the bracket in the base of the pan of the tile and still fasten to the rafter. Solar Tile Mount is adjustable for counter batten systems from ¾" to 3". The horizontal rail is directly above base fasteners giving greater uplift resistance than any other system. For superior waterproofing apply TRA Snow and Sun's butyl backed VersaFlash aluminum flashing. No tile flashing is needed on top of the tile for greater labor and material cost savings.
