Frequently Asked Questions (FAQ)

Choosing Geneco

The deregulation of the electricity market will encourage and promote competition within the various players in the electricity market and hence, provide competitively priced packages to consumers.

Since 2001, EMA has progressively opened the retail electricity market to competition to allow business consumers more options to manage their energy cost. Instead of buying from SP Group at the regulated tariff, eligible consumers can choose to buy from a retailer at a price plan that best meet their needs, or buy from the wholesale electricity market at the half-hourly wholesale electricity prices. Those who exercise this choice are termed as contestable consumers.

If you are contestable, you can choose to purchase electricity from one of the following methods:

  • From a Licensed Electricity Retailer (such as Geneco).
  • From the Wholesale Spot Market as a direct market participant.
  • From the Wholesale Spot Market through the Market Support Services Licensee (MSSL) (which is currently SP Group).

With the open electricity market, all businesses are eligible to apply for contestability regardless of consumption and application process is free of charge.

For your convenience, we will be pleased to assist you with the contestability application. You can call our Customer Experience Hotline for Business at 6363 6688 for assistance. Alternatively, you can also email to with the latest ACRA and the last 3 months of electricity bill.
