Companies using solar photovoltaic (PV) systems will soon be able to utilise the energy generated for self-consumption under a new net metering framework to be rolled out next year.
The move will help the companies involved to manage their eletricity bills in the wake of the coming power tariff hike from January onwards, aside from earning revenue by feeding electricity into the grid under the Feed-in-Tariff programme.
Sustainable Energy Development Authority (SEDA) Malaysia will work with Tenaga Nasional Bhd (TNB) in 2014 to develop a net metering framework which will pave the way for this, SEDA Malaysia CEO Badriyah Malek told The Malaysian Reserve.
Net metering is a system in which solar panels or other renewable energy (RE) generators are connected to a public-utility power grid and surplus power is transferred onto the grid, allowing customers to offset the cost of power drawn from the utility.
This, she said, will enable companies to enjoy reductions in electricity bills while promoting energy efficiency (EE) in the corporate sector.
SEDA chief corporate officer Dr Wei-nee Chen said net metering was in the past permitted under the Malaysian Building Integrated Photovoltaic (MBIPV) project for PV systems installed under the Suria 1,000 programme and demonstration projects.
Outside the MBIPV project, a net metering framework has yet to be agreed upon, said Chen who was the technical advisor for MBIPV until it ceased in 2010.
MBIPV was a joint initiative from 2006 between the Malaysian government, United Nations Development Programme and Global Environment Facility to promote widespread and sustainable solar PV market in Malaysia, with one of its objectives to develop a long-term BIPV programme that provides 30% BIPV growth and further cost reduction to the BIPV systems.
Hence, the Ministry of Energy, Green Technology and Water has tasked SEDA to develop the framework for the benefit of commercial PV applications.
“Also, the net metering concept under the MBIPV project is based on self-consumption and excess power can be credited or carried forward to the next month.
"However, in reality, this rarely happens as the owners’ electricity consumption almost always exceed the PV electricity generated each month,” Chen added.
