What is Net metering  Grid The termgridis used to talk about the network of poles and wires in the street that supply us with electricity. When people talk about ‘exporting to the grid’ they mean sending electricity out to the wires in the street, so that other people can use the power Terms in relation to Net Metering  Grid connection describes the arrangement where the energy produced by solar PV systems is sent to the electrical network by systems connected to it. The alternative would be a stand alone power system that charged batteries. Grid connected systems avoid the need to store energy in a battery, therebyreducing the cost of the system. In addition,you can draw electricity from the network if the power from your solar system is insufficient, at night for example. Grid Connected solar system Feed in Tariff  When electricity is sent from your solar system to the outside network, this is called exporting or ‘feeding into’ the grid. So, the price or tariff the electricity company pays for each unit of electricity is called afeed in tariff. The pricing for power usage is usually referred to as a consumption tariff Grid Connected solar system Feed in Tariff  Gross meteringdescribes a metering arrangement whereallsolar electricity generated is exportedto the outside electricity network through an independent meter. You would continue to have a separate meter that records how you use power. Gross metering is considered a good way to encourage householders to invest in solar, because the amount received is very obvious, and it is possible to easily offer a premium rate to householders for solar production  With this arrangement Government may get generation without any burden of capex, opex, infrastructure with almost nilltransmission loss . A WIN WINsituation . Gross Metering Roll-over system The generated energy is deducted from the participant’s energy consumption from the grid. This system utilises a single meter i.e. netmeter, which is similar to a conventional meter, but able to ‘roll over’ i.e. to discount from consumption the energy units fed into the grid as energy is supplied to the grid, thus offsetting it from the overall consumption. Therefore, roll-over does not require additional accounting efforts. Types of Net Metering  Banking system Participants can use an amount of energy from the grid equivalent to the value of the energy surplus they generate at a different time or billing period. These energy credits typically expire after one year. This system has the same technological requirements as the net purchase and sale system  Two types of Net metering based on financing model - Self owned net-metering model and other Third party owned Rooftop PV net metering model Type of Net metering  Government / Power developers need heavy investment, infrastructure in terms of Solar system , land , connectivity in case of MW scale projects  Off Grid System Batteries needs capital cost of Battery , replacement Advantages with Net metering over others  On grid system Extra power generated at any point of time is wasted  Net Metering is connected to the distribution system and thereby avoiding transmission and distribution TD losses . This is a strong rationale for rooftop solar projects in India, where the national average of TD losses hover at close to 20 , similar to many South Asian Countries  Net metering is panacea to all Advantages with Net metering over others  Benefits to rooftop owner The household owner avoids large upfront investment and on occasion avoids assuming technology or performance risk of solar systems. Net- metering allows the rooftop owner to save on power consumed from the grid . A part of savings in power consumption is shared with the developer by way of a lease rental Advantages with Net metering  Benefits to developer The leasing company generates revenues by way of lease rental from the rooftop owner under a contract. As it continues to be owner of the equipment, it also qualifies for claiming depreciation on the capital cost of the PV systems, with associated direct tax benefits  In order to make this model operational, electricity regulations need to be designed to remove specific barriers to participation of developers and intermediaries by government Advantages with Net metering over others Net-metering can potentially drive widespread implementation of distributed generation by incentivising end-users to adopt localized power generation through technologies such as solar. Net-metering is the silver bullet designed to help India and South East Asian Countries achieve greater energy security through generation at point of consumption distributed generation. Advantages with Net metering It is also supposed to help stabilise the national, regional and state grids, provide financial relief to the distribution companies DISCOMs through consumer default risk mitigation and reduction of ATC losses It is also to help cut down the per-capita energy footprint Advantages with Net metering  There are 3 main reasons for the disappointing adoption of net-metering by the consumers  the tariff structure a policy matter  grid-reliability a technical concern  DISCOM side storey  Above issues are relevant for the residential, commercial and industrial segments Reasons for disappointing adoption of net metering and solution  Reason 1 Tariff structure a policy issue If the energy supplied by the consumer to the grid selling is at a special, usually higher, tariff rate than the one at which electricity is bought from the grid buying, then it is called a “feed-in-tariff”. However, if the selling and buying are at the same tariff-rate usually the buying rate, then it is called net-metering and herein lies a problem if the buying rate is low due to subsidy etc Reasons for disappointing adoption of net metering and solution
