Infrastructure
Sikkim's roads are maintained by the Border Roads Organisation (BRO), an offshoot of the Indian army. The roads in South Sikkim and NH-31A are in relatively good condition, landslides being less frequent in these areas. The state government maintains 1,857 kilometres (1,154 mi) of roadways that do not fall in the BRO jurisdiction.
Sikkim receives most of its electricity from 19 hydroelectric power stations. It has achieved 100% rural electrification. Power is also obtained from the National Thermal Power Corporation and Power Grid Corporation of India. However, the voltage is unstable and voltage stabilisers are needed. Per capita consumption of electricity in Sikkim is 182 kWh. The state government has promoted biogas and solar power for cooking, but these have received a poor response and are used mostly for lighting purposes. In 2005, 73.2% of Sikkim's households were reported to have access to safe drinking water, and the large number of streams assures sufficient water supply.
On 8 December 2008, it was announced that Sikkim had become the first state in India to achieve 100% sanitation coverage, becoming completely free of public defecation, thus attaining the status of "Nirmal State".
