Energy in the developing world

Energy in the developing world has particular challenges due to relative poverty, and particularly in rural areas where the cost and logistics of distributing energy are high. But it is particularly important for the poorest people in the world to rise out of poverty as evidence demonstrates that rising prosperity, and especially the education and emancipation of girls and women, results in reduction in birth rates, which is vital to stabilising and eventually reducing the world's population.

Lighting up Ladakh Tata Power Solar

The case study showcased here is a shining example of how Tata Power Solar has leveraged its capabilities to touch the lives of millions in the beautiful Leh valley who for centuries have struggled to have ready access to energy for basic necessities – be it light, hot water or electricity.
The local renewable energy agencies and MNRE recognized the villages that were devoid of any sustainable source of energy, partnered with Tata Power Solar to design solar power project that powered over 100 villages where grid connectivity was next to impossible.
To solarize these many villages sprouting between Leh and Ladakh spread over a wide region, posed an enormous gamut of challenges due to the weather, altitude and topography of the region. Tata Power Solar proposed micro grids as a solution to power cluster of villages as well as provide decentralized solar power system to villages in the remote area. During 2009-13, a total of 86 micro grids of 5kWp-115kWp, with an aggregate capacity of 1MW were installed across remote and inaccessible villages in both Leh and Kargil. The installation of these solar powered micro grids brought an irreversible change through the region with access to sustainable source of energy. In addition to these microgrids, Tata Power Solar also commissioned lighting projects to over 300 villages spread across. As part of this, over 15,000 home lighting systems were installed, which include solar lanterns, home lighting systems and street lighting systems.

Ladakh's Remotest Village Now Runs Entirely On Its Own Solar Power Grid NDTV; 19 Oct 2017

The remote Himalayan villages are struggling with basic amenities even in the 21st century. They live in the dark with limited resources, medical support and education. The potential of thousands of children remains untapped. NDTV, in association with Global Himalayan Expedition (GHE), will power up Shade, which is around 420 km from Leh and is the remotest village of Zanskar, Ladakh. To achieve this herculean task, the team drove for 300 km on the Leh-Manali (NH3) highway to reach Sarchu, a serene campsite at the cusp of Jammu & Kashmir and Himanchal Pradesh. The last leg of the drive ended at the bottom of Shinkula pass. The team then trekked from Shinkula to Phugtal village, the ancient monastery of the Zanskar, and then to Shade. Solar micro-grids that produce green energy were installed to light up the village.
