How much does a wind power energy storage system cost in Sri Lanka

Is Sri Lanka a good place for offshore wind?

It has been identified that Sri Lanka has good conditions for offshore wind and its potential is estimated to be 56,000MW (referred to as 56GW-Giga Watts). In the NREL report the North-western, Northern, and Central provinces have been identified as the best areas for wind energy harvesting, in their classifications.

What is the wind energy resource of Sri Lanka?

An all island Wind Energy Resource Atlas of Sri Lanka was developed by National Renewable Energy Laboratory (NREL) of USA in 2003, indicates nearly 5,000 km 2 of windy areas with good-to-excellent wind resource potential in Sri Lanka. About 4,100 km 2 of the total windy area is on land and about 700 km 2 is in lagoons.

What is the wind potential of Sri Lanka?

The windy land represents about 6% of the total land area (65,600 km 2) of Sri Lanka. Using a conservative assumption of 5 MW per km 2, this windy land could support almost 20,000 MW of potential installed capacity. If the windy lagoons are included, the total theoretical wind potential increases to approximately 24,000 MW.

How much power can a wind turbine generate?

The amount of power that can be harnessed from wind depends on the size of the turbine and the length of its blades. The output is proportional to the dimensions of the rotor and to the cube of the wind speed. Theoretically, when wind speed doubles, wind power potential increases by a factor of eight. Wind-turbine capacity has increased over time.

How long does a monsoon last in Sri Lanka?

While the NE Monsoon lasts from December to February, the SW Monsoon lasts from May until early October. The stronger of the two monsoons, the SW, is felt over most of Sri Lanka’s west coast, as well as in the country’s inner regions and certain mountainous locations.

How does wind produce electricity?

Wind is used to produce electricity using the kinetic energy created by air in motion. This is transformed into electrical energy using wind turbines or wind energy conversion systems. Wind first hits a turbine’s blades, causing them to rotate and turn the turbine connected to them.
