* Tata evaluating 370 MW worth of projects for purchase
* Renewables sector offers lower but safer margins: Tata official
* India aims to double renewable energy capacity by 2017
* Land acquisition, low tariffs still hurdles: Tata official

NEW DELHI, Nov 26 India's Tata Power is looking for more acquisitions as part of a $260-million-a-year investment push into renewable energy, following last month's purchase of a wind farm in western Gujarat from AES Corp, a senior official said.
Part of the tea-to-telecoms Tata group, the firm is India's third-largest listed utility by revenue in the Thomson Reuters India Index.
Primarily a thermal power utility, it is targeting rapid expansion in renewables at home and overseas, aiming to add about 150 to 200 megawatts (MW) of wind capacity and 30 to 50 MW of solar power every year.
Its newly acquired plant has a capacity of 39.2 MW.
"After we announced the Gujarat acquisition, we have got a lot of interest from other owners of solar and wind operating assets who want to exit their investment," said Rahul Shah, the chief of business development for India business and renewables.
"So are we are evaluating a lot of these opportunities," he told Reuters in a telephone interview.
As coal and gas shortages and populist tariff regimes hobble the performance of thermal power stations, renewable energy players such as Tata and Welspun Energy want to tap the sector's potential in a growing but energy-starved economy.
But problems with acquiring land for projects, poorly enforced government policies, and a race to the bottom in bidding for solar projects are a drag on renewables growth, said Shah.
The margins on renewable energy are lower, at around 12 percent to 18 percent versus about 20 percent to 30 percent in the thermal sector, Shah said. "But in renewable energy it is a more predictable performance and a predictable return," he said.
Although the firm will look to sell a stake in its renewable business at some point, it has no timeline for this, Shah said.
The move could take the form of an initial public offering - although current market conditions are unfavourable - or a sale to a private investor, he added.
Tata operates about 400 MW of wind projects and 30 MW of solar. Shah said he hoped to buy more projects as soon as this fiscal year, which ends in March, and is evaluating projects worth a total of 370 MW for possible purchase.
India has targeted doubling its renewable energy capacity to 55,000 MW by 2017, from nearly 27,000 at the start of this year. Renewables contribute about 12.5 percent of India's energy, the 2012/13 report by the New and Renewable Energy Ministry shows.
Hurdles remain for the likes of Tata, Shah said. For example, rules stipulating that India's 28 states must source a certain part of their energy from renewables have not been properly enforced. Electricity tariffs paid by states can also be too low for companies to make money.
Other investors have echoed Tata's concerns. Welspun Energy, which is eyeing $1.6 billion of new investments by 2017, told Reuters in October that land acquisition and poor transmission networks remained problematic.
JinkoSolar Holding, a China-based solar panel maker, told Reuters that low prices for solar products, cut-throat competition and high interest rates dragged on growth.
Shares of Tata Power were down 0.8 percent by 0956 GMT, versus a fall of one percent in the benchmark index.
