management or executive positions. 22% of board directors are women, however, only 7% were designated as "executives", lower than the global average of 12%. Additionally, the eNPE (Employee Net Promoter Score) for women is a net negative (- 4) as compared to men (8), according to a survey conducted of 1000 participants. This indicated a low level of actual economic promotion for women, despite public and international initiative towards the contrary. Infrastructure Energy Scheduled rolling blackouts are a part of daily life. Electricity theft is widespread. After years of sub-standard maintenance and the South African government's inability to manage strategic resources, the state-owned power supplier Eskom started experiencing deficiency in capacity in the electrical generating and reticulation infrastructure in 2007. Such lack led to inability to meet the routine demands of industry and consumers, resulting in countrywide rolling blackouts. Initially, the lack of capacity was triggered by a failure at Koeberg nuclear power station, but a general lack of capacity due to increased demand and lack of government planning soon came to light. The supplier and the South African government has been widely criticised for failing to adequately plan for and construct sufficient electrical generating capacity, although ultimately the government has admitted that it was at fault for refusing to approve funding for investment in infrastructure. The margin between national demand and available capacity is still low or negative (particularly in peak hours), and power stations are under strain, such that surges in demand, which are common during winter, or drops in supply, often a result of a lack of coal for power plants, result in another phase of rolling blackouts. The government and Eskom are currently planning new power stations, at cost to the South African consumer. The power utility plans to have 20,000 megawatts of nuclear power in its grid by 2025. Water Some predictions show surface water supply could decrease by 60% by the year 2070 in parts of the Western Cape. The South African government planned to spend R69 billion on water infrastructure between 2008 and 2015. This involves building new dams and ancillary infrastructure, and repairing existing infrastructure. South Africa has an estimated total water capacity of 38 billion cubic metres, but will need 65 billion by 2025 if the economy is to keep on growing. The massive urban migration has placed further strain on the country's ageing water infrastructure and created a large backlog.
