Buoyed by the growth in the transmission and distribution segments, power equipment manufacturer Diamond Power Infrastructure (DPIL) plans to invest Rs 770 crore over the next three years to fuel its expansion plans. There is huge growth potential in transmission as well as distribution sectors as power generation is expected to grow by 80,000 mw in the 12th Plan period. DPIL also plans to introduce a few more products including unitised substations and gas cables. With the introduction of these products, the company expects its revenue to grow 30-35 per cent next fiscal. Moreover, the company expects Rs 1,200 crore revenue this financial year.
