DETROIT, June 3 (Reuters) - Tesla Motors Inc is now looking at three sites, instead of two, to begin construction for its lithium-ion battery plant in the United States, Chief Executive Elon Musk said on Tuesday.
The leading U.S. electric car maker expects to trim from five the number of states from which it is choosing to build its battery plant, dubbed the "gigafactory," but a decision on the final site will not come before year end.
"We're probably going to do two or maybe three states all the way to creating a foundation and completing the plans and getting approval," Musk told shareholders at the company's annual meeting in Mountain View, California. "It might actually be three states we do it in."
Tesla previously said it would pick two winners from among Nevada, Arizona, New Mexico, Texas and California and start developing the sites simultaneously to minimize risk of delays after groundbreaking. Analysts have said Tesla needs to finalize plans for the plant soon if it wants to meet its 2017 production target.
Musk, who reaffirmed he will remain CEO of Tesla at least another four or five years through the production of a high-volume car dubbed Gen 3, said the company was "quite advanced" in its planning for the battery plant. He said the gigafactory is being developed in conjunction with the third-generation car, which will cost about $35,000 and hit the market in late 2016.
The plant is meant to produce the batteries in high volumes at lower costs as a way to help the company drive down the price of the Gen 3 car. Musk said he was optimistic the company could do better than its 30 percent target on cost reduction and supplier partner Panasonic Corp was also convinced.
Panasonic previously said it expected to be the sole manufacturer in Tesla's gigafactory.
Musk added that a next-generation roadster model was probably five years away.
After the Gen 3 car, Musk said it made sense for Tesla to look at building electric trucks and probably a vehicle that would cost less than $35,000.
Musk also said Tesla was expanding its relationship with contract manufacturer Foxconn, which is listed on the Taiwan stock market under the name Hon Hai. He said potential alliances with companies like Foxconn could allow Tesla to expand production faster.
A company spokeswoman declined to outline Tesla's relationship with Foxconn.
Musk also said Tesla is making progress on developing self-driving technology for its cars, and added he was confident that within a year, the automotive industry will allow drivers to go from highway on-ramp to exit without touching any vehicle controls.
