In terms of renewable sources like solar and wind, weather impacts supply. California's duck curve shows the difference between electricity demand and the amount of solar energy available throughout the day. On a sunny day, solar power floods the electricity generation market and then drops during the evening, when electricity demand peaks. [11]
Electricity market is characterized by unique features [12] that are atypical in the markets for commodities or consumption goods.. Although few somewhat similar markets exist (for example, airplane tickets and hotel rooms, like electricity, cannot be stored and the demand for them varies by season), [13] the magnitude of peak pricing (peak price can be 100 times higher than an off-peak one ...
Historically, rates have been minimal at night because the peak is during the day when all sectors are using electricity. Increased demand requires additional energy generation, which is traditionally provided by less efficient "peaker" plants that cost more to generate electricity than "baseload" plants. [ 7 ]
A 2013 study estimated the merit order effect of both wind and photovoltaic electricity generation in Germany between the years 2008 and 2012. For each additional GWh of renewables fed into the grid, the price of electricity in the day-ahead market was reduced by 0.11–0.13 ¢/kWh.
In some countries plant operators are entitled to receive compensation for such interventions. In a competitive electricity market the situation can be handled by a balancing mechanism, in which any imbalance from the schedule (typically a day-ahead schedule) is penalized, either using the price from a balancing market or a calculated price.
To decarbonise the energy sector, the Singapore Energy Story where Singapore will harness the 4 Switches to transform its energy supply while ensuring continued energy reliability and cost-competitiveness was announced at SIEW 2019. [10] These efforts are in support of Singapore's goal to achieve net-zero by 2050. [11]

The electricity sector in Singapore ranges from generation, transmission, distribution and retailing of electricity in Singapore. Electricity sector in Singapore is regulated by the Energy Market Authority (Chinese: 新加坡能源管理局). As of 2015, Singapore uses natural gas (95%) and waste (4%) for power stations' fuel.
