Imagine your monthly electricity bill is a dungeon. Every month you walk in, get hit by charges you did not see coming, and walk out S$10,000 to S$100,000 lighter. You cannot fight the dungeon alone. But what if there was a way to organise a party, take down the boss, and pocket a share of the loot? Welcome to Demand Response.
Chapter 1 — Prologue: The Dungeon Spawns
Singapore is a tiny island running on a gas-powered grid. About 95% of our electricity comes from burning natural gas. Gas is bought on global markets. Global markets are volatile. The moment an LNG ship is delayed, a gas field has a problem, or Europe turns up its heating — Singapore’s electricity price spikes.
Think of it like this: the electricity grid is a dungeon map, and at the end of that map sits a BOSS. Its name is DEMAND SPIKE. This boss does not show up every day. But when it does, it hits hard — and every business on the grid takes damage at the same time.
| RAID ENCOUNTER — SINGAPORE POWER GRID | LEVEL MAX | |||||
|
DEMAND SPIKE Type: Final Boss | Spawns: Peak demand hours, volatile gas markets | Created by: Shortage
|
||||||
The boss is created by shortage. When demand is high and supply is tight, the grid calls on its most expensive power plants — old, inefficient gas peakers that cost over S$600 per MWh to run. Every generator on the grid then gets paid that high price. The clearing price resets to the worst case.
Real-World Damage Report: One Singapore C&I customer’s electricity bill jumped from S$26,108 in Q2 2023 to S$63,313 in Q3 2023. Same site. Same operations. The boss showed up — and there was no defence in place.
Chapter 2 — The Lone Wolf Problem
Here is where a lot of people get stuck. They think: “My building uses maybe 1 MW. Can I just turn off some lights and earn money from the grid?” The short answer: sort of, but you will barely tickle the boss.
The grid operates at scale. Singapore’s total demand at peak exceeds 7,500 MW. One building reducing 0.1 MW is like one player swinging a basic sword at a raid boss with millions of HP. You will die before the boss even notices you.
| Guild Power Meter — DR Aggregation Level | ||
| Lone Wolf (1 site) |
0.1 MW |
No price impact |
| Small Party (10 sites) |
100 MW |
S$600 → S$500/MWh |
| Raid Party (50 sites) |
1,800 MW |
S$600 → S$350/MWh |
| Full Raid (Max Agg.) |
2,200 MW |
S$600 → S$150/MWh |
This is the core insight: aggregation is everything. A party of 10 sites reducing demand together can drop the market price from S$600 to S$500 per MWh — saving S$0.93 million every hour a spike occurs. A full raid party can cut the price by 75%, saving S$3.24 million per hour. Those savings get shared back to every site in the party.
The Aggregation Principle: Demand Response only works at scale. That is why you need an Aggregator — a guild leader who organises all the players, handles the market bidding, and distributes the loot.
Chapter 3 — Join the Guild
Singapore’s Energy Market Authority (EMA) runs two official DR programmes. Think of them as two different character classes, both using the same weapon — your battery.
|
🛡 IL Class — Interruptible Load Passive Defender Earns standby gold every half-hour you stay enrolled, whether or not you are called to battle. S$15–20 / MW / 30 min |
⚔️ DR Class — Demand Response Active Fighter Called when prices spike. Paid per verified MWh of reduction delivered. High risk — very high reward. Up to S$4,500 / MWh |

DR Performance Revenue

Chapter 4 — The Raid Event
You have enrolled. Your battery is online. The boss spawns. Here is what happens in real time — from market alert to loot distribution — while you are in a meeting and your facilities team is drinking coffee.
T-60 minutes
Market Alert: USEP price surging
Singapore’s spot price begins climbing above the DR trigger threshold. Gas supply is tight. Peaker plants are being called in.
T-30 minutes
SolarWarhouse software submits DR bids to EMC
Our dispatch system reads market signals and submits half-hourly reduction bids automatically. No action needed from your team.
T-0: Event begins
Your BESS dispatches — battery discharges
The battery discharges, reducing your site’s grid import. Your operations run exactly as normal — lights stay on, machinery runs, AC keeps cooling.
T+30 minutes
Reduction verified by EMC metering
The Energy Market Company cross-checks your half-hourly smart meter data. Verified reduction = payment triggered. Your dashboard updates in real time.
Overnight
Battery recharges at low tariff
The BESS quietly recharges during off-peak hours at the cheapest overnight rate. Ready for the next event. Fully automated.
The Key Insight: The battery does not change your operations. It changes your building’s relationship with the grid. Your team runs the site as usual. The battery fights the boss in the background.
Chapter 5 — The Loot Distribution
Every time the aggregated DR party beats the DEMAND SPIKE boss, the grid saves real, quantifiable wholesale market money. In 2024, Singapore’s DR programme delivered over S$700 million in annual wholesale savings to the entire system.
Singapore’s rules say participants who successfully deliver verified reductions receive approximately one-third of those savings. That is your loot share.

Now zoom in to a single site. A major Singapore commercial venue with 3.4 MW peak demand installed a 1 MW / 2 MWh BESS at zero capex. Here are their Year-1 numbers:
| Scenario | Year-1 Revenue | Payback | 12-Year Gross | IRR |
|---|---|---|---|---|
| Conservative (P-90) | S$517K | 3.5 yr | S$6.0M | 27.3% |
| Base Case (P-50) | S$625K | 2.7 yr | S$7.2M | 36.7% |
| Upside (P-10) | S$885K | 1.8 yr | S$10.2M | 56.8% |
Chapter 6 — The Guild Master
We are the Guild. You are the building owner. We handle the capital, the weapons, the raid coordination, and the loot accounting. You provide the site, carry on your operations, and collect your revenue share.

Final Chapter — Boss Defeated. What Now?
Singapore has an estimated 400 MW of demand response potential. Today, only 167 MW is enrolled. More than half the loot is still unclaimed. The boss keeps spawning. The savings are real. The mechanics are proven.
The Bottom Line: A 30-minute price spike can generate a week’s worth of revenue value. Your building’s battery can capture that — automatically, safely, without disrupting a single operation. The game is real. The loot is real. The guild is open.
