New Delhi: The country's largest carmaker Maruti Suzuki India is considering to set up new plants along with two new upcoming units in Manesar, as it aims to sell up to 30 lakh units every year by 2015-16.

According to sources close to the development, the firm has already started internal discussions to set up its 7th plant and a final decision to this effect is likely to be taken within the next one year.

At present MSI is setting up two new units inside its Manesar facility at a total investment of Rs 3,625 crore. While the existing plant in Manesar can produce 3.5 lakh units annually, its three units in Gurgaon have a combined annual capacity of 8.5 lakh units.

Sources said the new plant could be either at the Manesar facility or elsewhere depending on the infrastructure situation once the two new units there are completed.

Sources, however, added that the company will consider Manesar complex, which is spread across about 600 acres of land, as the first option for the new facility.

"In any case, the expansion is likely in Manesar. But the company is also looking at the infrastructure aspect to avoid any kind of congestion in the area... In a year's time all will be cleared and a decision is expected by March-April, 2012," a source said.

If MSI decides that Manesar cannot handle too much of load after the two upcoming plants go on stream, then it will look for a new location for the new plant, the source added.

MSI's present overall capacity is 12 lakh units per year. Once the new units, currently being constructed at Manesar, becomes operational by 2012-13, the company's total production capacity will go up to 17 lakh units annually.

The two new plants will have a capacity of 2.5 lakh units annually. The company is aiming to open the second unit in Manesar by September-October this year, while the third one is scheduled to be operational in 2012-13
