“…That law remained practically inactive until December 2014 when the required Ministerial decision concerning the exact provisions for NEM was published [22]. This ended a long discussion between interested parties that lasted for more than one year and after a public consultation on a certain proposal, which was examined in a recent article [23]. The main provisions of the policy are the following:…”

Abstract:The photovoltaic market has recently experienced an enormous expansion, mainly due to the generous Feed-in-Tariffs (FiTs) adopted by many countries. However, in the recent years FiTs have been considerably reduced or even disappeared as their role in the PV deployment has ended. One of the alternatives is the Net-Metering (NEM) policy, which has attracted the interest of stakeholders as it provides a basis for the efficient collaboration between generation and the consumption profiles of the consumer. Currently, there is a lack of a universal policy harmonizing the respective legislations of the E.U. member countries. This paper proposes a novel generalized methodology for the techno-economic assessment of different NEM policies in terms of profitability for the prosumer. The methodology is tested in a formulated case study based on the current NEM policy in Greece. The method proposed uses as inputs the averaged load profiles constructed from real measurements collected from 31 consumers in the Thessaloniki area and evaluated PV production. The current NEM policy and four alternatives are examined, using as additional input the average system marginal prices of the year 2013. The results show that the proposed methodology is capable of evaluating a wide variety of NEM policies and can lead to suggestions for policy adaptation in order to establish a win-win contract between all interested stakeholders.

“…Next, some countries are implementing increasing-block rate tariff, which means the electricity rate per kWh increases as the volume of consumption increases. Thus NEM will not necessarily mean a profitable investment, especially for small consumers if the first electricity tariff block is comparatively low [15].…”

The current Malaysia’s Net Energy Metering (NEM) scheme has been updated in 2019 that credits excess generation into the next billing month at retail rate compare to at displaced cost. The new NEM may attract more installation of solar photovoltaic (PV) system among residential customers. However, it is discovered that customers with low monthly electricity consumptions are still not benefited since their electricity cost is lower than the PV generation cost. Implementing time-of-use (TOU) pricing on NEM scheme may overcome the problem as it based on hourly energy usage. This paper compares the annualized energy cost of residential PV system under different TOU prices and NEM scheme. The results show that an optimized TOU prices as suggested in this paper may give financial benefits to all residential customers with PV system, including the one with low monthly consumption.

Net energy metering (NEM) is a financial scheme that allows a consumer to generate, use and sell their excess energy to the grid. The main purpose of NEM is for self-consumption to reduce demand from the grid. It will allow customer to avoid being charged with expensive electricity tariff and hence reducing their monthly electricity bill. In other words, the annualized electricity cost could be reduced. NEM is commonly offered to residential solar photovoltaic (PV) system. Different PV size will determine the amount of energy that can be generated. This paper compares the annualized electricity cost of different residential customer types (large, medium and small) for different PV size under Malaysia’s net energy metering (NEM) scheme. This paper utilizes the load profile and solar irradiation data for Malaysia. The results show that high PV size does not guarantee reduction in annualized electricity cost especially for medium customers as the excess PV generation can only be accumulated for 24 months. Large customers may have benefited the most with lower annualized cost with larger PV system, while small customers may not have benefited at all.
