Why most businesses overpay
Electricity is a significant operating cost for most Singapore commercial and industrial businesses, often the third or fourth largest after rent and labour. Yet it receives a fraction of the procurement attention that other costs do. Contracts are renewed passively, bills are paid without audit, and the assumption that "electricity prices are what they are" goes largely unchallenged.
The reality is different. Singapore's Open Electricity Market, fully liberalised since 2019, gives every business the tools to compete aggressively for better pricing. The businesses that use those tools systematically, reviewing contracts, auditing bills, timing renewals, consistently outperform those that don't, often by ten to twenty percent on their annual electricity spend.
Here are seven strategies that make the most meaningful difference.
1. Never let your contract lapse
This is the single most expensive mistake a business can make. When an electricity contract expires without a new agreement in place, your account automatically defaults to SP Group's regulated tariff. This tariff is adjusted quarterly by the Energy Market Authority and is structurally higher than what you would pay under a competitively tendered retail contract.
In a period of rising wholesale prices, the gap between a lapsed tariff and a well-timed retail contract can reach fifteen to twenty-five percent. For a business spending $50,000 a month on electricity, that difference is material.
Set a calendar reminder three to six months before your contract expires. That is your window for a proper renewal process: enough time to run a full tender, compare offers, and decide without urgency.
2. Time your renewal to market conditions
Not all moments are equal for locking in an electricity contract. Singapore's wholesale electricity prices are closely linked to global liquefied natural gas (LNG) prices, since most of the island's generation capacity runs on gas. When LNG prices are elevated, as they were following global supply disruptions in 2021 and 2022, fixed-price contracts embed that high pricing for their entire term. When LNG prices ease, a well-timed renewal can lock in savings that persist for years.
This does not mean you should try to time the market with precision. It means you should be aware of where prices are in their cycle when you renew, and factor that context into your contract length decision. Locking in a two-year fixed contract at a market peak is a much costlier error than renewing on a shorter term until conditions improve.
3. Conduct an annual bill audit
Your electricity bill contains more than a unit rate and a total. It includes network charges, capacity charges, reactive power penalties, metering fees, and other line items that many businesses pay without understanding. Some of these charges are avoidable or reducible; others are simply worth understanding so you can plan around them.
A bill audit does not need to be complex. At minimum, it should confirm that you are being billed at the contracted rate, that your peak and off-peak usage patterns are as expected, and that any ancillary charges are correctly calculated. Billing errors are not uncommon, and they are almost always in the retailer's favour.

4. Understand your load profile
Your usage pattern, how much electricity you consume, and when, determines which contract structure delivers the best value for your business. A business with flat, predictable consumption across the day and week benefits from different structures than one with sharp peaks during business hours and low consumption at night.
High load-factor consumers (those with relatively consistent consumption throughout the day) often find fixed-price contracts competitive. Businesses with more variable consumption may benefit from indexed or discount-off-tariff structures that track the market rather than locking in a potentially disadvantageous fixed rate.
Before your next renewal, ask your current retailer or broker for a half-hourly load data export for the past twelve months. This data is the foundation of any serious contract comparison, without it, you are guessing about your own consumption.
5. Use an independent broker for your next tender
The most effective way to ensure you are getting competitive pricing is to tender your load across the full market simultaneously, rather than negotiating with a single retailer. An independent broker, one with no exclusive relationships with any retailer, does exactly this.
A proper tender process involves submitting your consumption data to multiple licensed retailers, receiving standardised offers, and comparing them on a like-for-like basis. The difference between the best and worst offers in a competitive tender is often ten percent or more, simply because retailers price differently based on their current book position, risk appetite, and appetite for new customers.

A well-run tender process typically takes two to three weeks from data submission to final offer comparison. The time investment is modest; the savings potential is not.
6. Review your contract structure annually
The contract structure that was right for your business two years ago may not be right today. Your consumption pattern may have changed as your business grew or contracted. Market conditions may have shifted significantly. Your risk appetite may have evolved.
An annual review does not require you to switch contracts. It requires you to ask whether your current arrangement still makes sense given current conditions, and to have enough market data to answer that question. Businesses that do this consistently avoid the inertia that leads to passive contract rollovers at uncompetitive rates.
7. Check your carbon tax provisions
Singapore's carbon tax was introduced in 2019 at S$5 per tonne of CO₂ equivalent and has been rising on a published schedule toward S$50–80 per tonne by 2030. This matters for electricity consumers because carbon tax costs flow through the supply chain from generators to retailers to businesses.
How your contract handles this pass-through varies significantly. Some contracts absorb carbon tax movements within the contracted rate; others pass them through at cost or with a margin. As the carbon tax continues to rise, the difference between these provisions will become increasingly significant to your total electricity spend.
If your current contract does not have clear carbon tax provisions, or if those provisions are ambiguous, this is worth raising with your retailer or broker before your next renewal.
Electricity is not a fixed cost. It is a managed one. The businesses that treat it that way, reviewing contracts, auditing bills, timing renewals, consistently find room to save.
Where to start
If you are reading this and are not sure where your current arrangement stands, a bill audit is the right first step. It is low-effort, requires no commitment, and gives you a clear picture of whether there is meaningful savings available in your current setup.
From there, the most impactful single action is usually a competitive tender ahead of your next renewal. If you would like to understand what that process looks like for your business, get in touch and we can walk you through it.
