State Electricity Boards own around 50% of total installed capacity. Public companies owned by the central government, including the National Thermal Power Corporation (NTPC), the National Hydroelectric Power Corporation (NHPC) and the Nuclear Power Corporation of India Ltd. (NPCI) control around 34% of India's total capacity. The eastern and north-eastern regions, traditionally the poorest regions in terms of GDP per capita (Figure 7) have also much less installed capacity.
