Singapore is reviewing its regulations for intermittent energy sources such as solar power and wants the public's views.

The Energy Market Authority (EMA) launched a public consultation paper on the issue on Monday during the start of Singapore International Energy Week. The paper will be available on the agency's website and the deadline for comments is January next year.

Intermittent energy sources include solar and wind energy, and their output depends on the weather and the environment. This means that if not managed properly, their use could result in black-outs and power disruptions.

The consultation paper includes how registration processes can be simplified so that small consumers with intermittent generation sources, such as solar panels, can be paid for supplying their excess electricity to the national power grid.

During his opening remarks on Monday for the Energy Week's Singapore Energy Summit, Minister in the Prime Minister's Office S. Iswaran also announced that the cap for intermittent energy supply to the national grid will be raised from 350MWp to 600MWp.

He added that six power generation companies here including Senoko Energy and Tuas Power Generation have expressed interest in working with the Singapore Exchange to develop an electricity futures market, which is expected to be launched next year. The EMA also plans to launch a new demand response scheme in 2015, which will help to lower peak electricity demand.
