NEC to test energy management for India base stations

NEC Corporation and Pixela Corporation will begin testing the use of energy management systems to monitor and control renewable photovoltaic (PV) energy and lithium-ion rechargeable battery systems to power mobile base stations in India this year in a two-year project run by Japan’s Ministry of Economy, Trade and Industry (METI) and New Energy and Industrial Technology Development Organization (NEDO). The project will also explore to what extent the power used by the air conditioning units that protect radio equipment housed alongside the towers can be reduced by coating the walls and roofs of the shelters with high…

NEC Corporation and Pixela Corporation will begin testing the use of energy management systems to monitor and control renewable photovoltaic (PV) energy and lithium-ion rechargeable battery systems to power mobile base stations in India this year in a two-year project run by Japan’s Ministry of Economy, Trade and Industry (METI) and New Energy and Industrial Technology Development Organization (NEDO). The project will also explore to what extent the power used by the air conditioning units that protect radio equipment housed alongside the towers can be reduced by coating the walls and roofs of the shelters with high-solar reflectance photocatalytic paint to curb temperature levels.

With the sharp rise in the number of mobile phone subscribers nationwide, Indian operators are rapidly expanding their base station networks. However, there are many regions with fragile power supplies that suffer from frequent outages and others that are off-grid. Telecom carriers currently use diesel generators either as a back-up to grid power or the primary power source in rural sites, but the expense of the fuel accounts for a large percentage of their operating costs.

The Indian Department of Telecommunications has set network operators a target of ensuring that 50% of telecom tower sites in rural areas and 20% of urban telecom tower sites should run on hybrid power, comprising of grid power combined with renewable energy by 2015. The decision comes as the Indian government, which heavily subsidizes diesel, looks to lessen the country’s reliance on foreign oil and reduce greenhouse gas emissions. By 2020 75% of rural and 33% of urban stations will need to run on hybrid energy. The use of renewables with diesel generators as a back-up are also being explored for some off-grid locations.

A total of 62 mobile phone base stations will benefit from the technologies across India, including sites in the suburban areas of Delhi and Mumbai. The energy management system will be installed at 20 sites, while photocatalytic paint will be applied to 52 sites and a combination of both at some locations. NEC predicts that if these measures were introduced across all 400,000 mobile phone base stations in India, base station power usage would be cut by 50% and the industry would save one million litres in diesel fuel annually.

According to forecasts by Pike Research, part of Navigant’s Energy Practice, annual deployments of base stations powered by using renewable or alternative energy sources will rise to 84,000 by 2020, up from few than 13,000 sites worldwide in 2012. The report concludes that in all, more than 390,000 such base stations will be deployed from 2012 through 2020.

The tests are being carried out jointly by NEC and Pixela Corporation as contractors in a demonstration project run by Japan’s Ministry of Economy, Trade and Industry (METI) and Japan’s New Energy and Industrial Technology Development Organization (NEDO) focusing on international energy consumption efficiency technologies and systems. NEDO has recently signed a memorandum of understanding (MOU) with India’s Department of Economic Affairs, Ministry of Finance (MOF/DEA), Department of Telecommunications (DOT), Ministry of New and Renewable Energy (MNRE), GTL Infrastructure and VIOM Networks to carry out the field tests.

The MoU has been signed under the aegis of India-Japan Energy Partnership. This project is the first under India-Japan bilateral co-operation in the energy sector, which is priority of the new Indian government.
