Renewable Energy Technology Solutions for Tower Industry
RET solutions like sunlight based photovoltaic, wind power; biomass and energy units are the energy efficient technologies of choice for alternative solutions at telecom tower industry today. Hybrid solutions that join diesel generators with RETs and batteries are being redone. Energy components are being introduced as a standalone solution replacing the current diesel generator. In a set number of situations where electrical network accessibility is near 20 hours a day or more, the diesel generator at the tower site has been replaced totally by upgrading the current battery limit prompting change in financial aspects and decrease of carbon discharges nearby. Batteries are and will keep on being a key part of any reinforcement power solution however a nitty gritty dialog on batteries has been prohibited in this discourse.
Customization of the RET solution for a specific site requires an intensive comprehension of every innovation and its important financial aspects. The relative attributes, favorable circumstances and constraints of sun based photovoltaic, wind force, biomass and energy component advances are talked about underneath.
1. Solar Photovoltaic
India gets abundant sunlight for around 300 days a year. The day by day normal sun based vitality occurrence crosswise over India differs from 4 to 7kWh/m2 considering 1000Wh/m2 of standard sunlight. This makes an interpretation of to 4 to 6 hours of daylight for each day that can be utilized by a Solar Photovoltaic (SPV) installation.
Since a photovoltaic framework can just produce power amid sunlight hours, it is not doable to make a standalone solution utilizing this framework. By and large, a sun based photovoltaic reinforcement power framework is planned with a mix of proper measured battery banks, or used to counterbalance the operation of a reinforcement power framework like a diesel generator for around four hours for every day when sunlight is accessible.
To design a sun powered photovoltaic establishment for a telecom tower site, definite assessment of the heap profile of the site, climate conditions at the site all through the schedule year, battery productivity, charge controller effectiveness, power misfortune because of dust aggregation and accessible region for establishment of the sun based photovoltaic boards ought to be considered.
The Ministry of New and Renewable Energy (MNRE) is supporting off-lattice sun powered photovoltaic telecom applications by giving capital sponsorship of 30%. India Renewable Energy Development Agency (IREDA) offers delicate advances at 5% enthusiasm for renewable vitality ventures.
2. Wind Power
Reasonability of wind force innovation is reliant on the span of valuable wind pace and nature of wind. The wind speed profile fluctuates consistently. Amid January and February the wind velocity is at its most reduced and crests amid September. The pace lessens from October once more. In India quality wind velocity is accessible in conditions of Karnataka, Maharashtra, Tamil Nadu, Gujarat, and in some parts of Andhra Pradesh, Orissa and Madhya Pradesh.
With a yearly national normal of 5-6 m/sec wind speed wind speed and a normal term of 4hrs/day, the wind power turbine answer for telecom towers can’t shape a standalone solution. The dependence on accessibility of astounding wind speed has made the innovation unsatisfactory for less windy destinations.
Like sun powered photovoltaic, regulatory and policy enticements are available for wind power innovation which facilitate empowers its application with telecom towers. The motivating forces incorporate 100% remote direct venture, 35% quickened deterioration and exclusion of extract obligation. MNRE offers 30% capital endowment for telecom applications up to most extreme of INR 1, 00,000/kW.
By definition “Biomass” is natural material got from living or as of late dead living beings. In India, biomass is utilized as an essential vitality source since centuries as dry wood, leaves and cows excrement. Around 32% of the aggregate essential vitality utilized as a part of the nation is still gotten from biomass and more than 70% of the nation’s populace relies on it for its vitality needs. Since February 2012, 1142 MW of biomass based era limit has been introduced in India.
In 2008-2009, the Rockefeller Foundation mutually with Indian accomplices took an activity to address twin difficulties of vitality hardship and neediness via Smart Power for Environmentally Sound Economic Development (SPEED) program where the need of diesel replacement & rural electrification is incorporated with rural community development. As country charge and financial improvement is joined in this activity, biomass power plants exhibit the chance of giving answers for both. Service of Non-Conventional Energy Sources’ four Action Research Centers (ARCs) created gasifiers extending from 3.5 – 100 kW for telecom and other little limit applications.
There are a few motivating forces, including concessional traditions obligation on import of hardware and parts, extract obligation exception, quickened deterioration on real segments, help from assessments and capital endowment for setting up of biomass force extends that are being given by the administration. Alongside this, as a piece of limited time strategy State Electricity Regulatory Commissions (SERCs) have decided the particular duty available will be obtained from biomass power.
4. Fuel Cells
Power devices change over concoction vitality into electrical vitality. There are diverse sorts of power modules that have working qualities that are affected by the kind of parts utilized as a part of their outline. The different sorts of energy components that can be utilized for telecom towers are Molten Carbon Fuel Cell (MCFC), Proton Exchange Membrane (PEM) & Solid Oxide Fuel Cell (SOFC). These energy units uses fills like hydrogen, methanol, regular gas and other hydro carbons. Power modules can run ceaselessly the length of fuel is accessible and henceforth make a decent standalone renewable vitality solution for replacing the diesel generator. Energy component based frameworks can be intended to be particular permitting a nearby match of the introduced ability to the force interest of the site. Moreover, any expansion in the interest at the site because of expanded occupancy can be met by basic expansion of ability to the energy component framework. Energy units have higher proficiency when contrasted with other RET arrangements. Inferable from fundamentally better proficiency versus load qualities, power device frameworks can be utilized as a part of decrease of the vitality prerequisite of the telecom site in contrast with diesel generators.
Contrasted with different innovations, power module based answer for telecom towers are generally new in India. Some trial ventures have been attempted by telecom organizations. While the innovation has demonstrated itself through these trials to give control, the accessibility and cost of the fuel should be key region of center to guarantee expansive scale selection.
