tariffs. This is done in order to encourage investment in the country's energy sector. Such investments have included a 600 MW producing project implemented by the Chinese Shenhua Group, and the 1200 MW producing Thar Engro Coal Power Project. In Pakistan, mineral mining operations are subject to provincial administration. However, in 2011, to encourage large-scale investment in coal mining, the federal government authorized the creation of the "Thar Coal & Energy Board" (TCEB), a statutory corporation that would directly administer the extraction and use of Tharparkar's large energy resources. In March 2019, new members were appointed to the TCEB including female Member of National Assembly (MNA) Shazia Marri (NA-216). However, the TCEB's charter requires that there should be one female MNA from either Tharparkar, Umerkot or Mirpur Khas districts on the board. An exception was made, as MNA Mahesh Malani and Senator Krishna Kohli were from and represented the Thar region, despite neither directly fitting the "female MNA from Thar" requirement. The Sindh Engro Coal Mining Company in Tharparkar supplies electricity to the national grid. Despite this, the large majority of the 2,300 registered and almost 2,000 unregistered Thari villages have no electricity supply. Energy shortages and blackouts are common, and one outage during a heat wave lasting 22 hours resulted in the deaths of several hospital patients. An informal announcement made by the Sindh government declared that electricity would be freely provided to Tharparkar, however this has not happened, and electricity continues to be supplied by private companies such as Hyderabad Electric Supply Company. Several entities have raised issues of potential environmental and health impacts that could result from extensive coal mining and use. The pollution and harm to the environment caused by coal mining and use in the region have led to destruction of habitat, as well as the large-scale displacement of local communities. Health effects of lignite pollution include increases in the risk of cancer, as well as heart and lung problems. Social movements, which some Thari people are involved in, have hoped to address these challenges. Solar Bahawalpur district's Quaid-e-Azam Solar Park, the largest photovoltaic power station in Pakistan, has a photovoltaic electricity output (PVOUT) of 1596 kWh/kWp per year and a global horizontal irradiance (GHI) of 1925 kWh/m2 per year. In comparison, Tharparkar has a PVOUT of 1642 kWh/kWp per year and a GHI of 2005 kWh/m2 per year. In January 2015, at a cost
