and mass education. In the study, 67% of the sampled listened to radio and 80–90% read newspaper. Most of the major Indian telecommunication companies are present in the state, such as Airtel, Vi, Jio and BSNL. Mobile connections outnumber landline connections by a wide margin. As of 2011, the state-controlled BSNL has 57,897 landline subscribers and GSM mobile service connections. There are 84 telephone exchanges (for landlines) and 716 post offices in the state, as of 2011. Electricity Till 2014, Tripura was a power deficit state. In late 2014, Tripura reached surplus electricity production capacity by using its recently discovered natural gas resources, and installing high efficiency gas turbine power plants. The state has many power-generating stations. These are owned by Tripura State Electricity Corporation (TSECL), natural gas-powered thermal power stations at Rokhia and Baramura, and the ONGC Tripura Power Company in Palatana. The ONGC plant has a capacity of 726.6 MW, with the second plant's commissioning in November 2014. It is the largest individual power plant in the northeast region. The state also has a hydro power station on the Gumti River. The combined power generation from these three stations is 100–105 MW. The North Eastern Electric Power Corporation (NEEPCO) operates the 84 MW Agartala Gas Turbine Power Plant near Agartala. As of November 2014, another thermal power plant is being built at Monarchak. With the newly added power generation capacity, Tripura has with enough capacity to supply all seven sister states of northeast India, as well export power to neighbouring countries such as Bangladesh. With recent discoveries, the state has abundant natural gas reserves to support many more power generation plants, but lacks pipeline and transport infrastructure to deliver the fuel or electricity to India's national grid. Irrigation and fertilizers As of 2011, of land in Tripura cultivable, of which has the potential to be covered by irrigation projects. However, only is irrigated. The state lacks major irrigation projects; it depends on medium-sized projects sourced from Gumti, Khowai (at Chakmaghat) and Manu rivers, and minor projects administered by village-level governing bodies that utilise tube wells, water pumps, tanks and lift irrigation. ONGC and Chambal Fertilizers & Chemicals are jointly building a fertiliser plant to leverage ONGC's natural gas discoveries in Tripura. Expected to be in operation by 2017, the 1.3 million tonnes per year plant will supply the northeastern states. Drinking water Drinking Water and Sanitation (DWS) wing]
