NSW Electricity Plans 2026
New South Wales has three electricity distribution networks. Your network determines which plans are available. Here are the best rates for each.
📊 Best Plans — Sydney Metro (Ausgrid)
🗺️ NSW Networks
🏙️ Ausgrid
Sydney metro, Central Coast, Newcastle, Hunter. 1.7M customers. Most competitive rates.
🌊 Endeavour
Western Sydney, Illawarra, South Coast, Blue Mountains. ~1M customers.
🏔️ Essential
Regional/rural NSW — 95% of landmass. 870K customers. Higher rates.
💡 Key Takeaway
If you're in Sydney metro and haven't switched in 12 months, you're likely paying 32-38¢/kWh on a standing offer. Switching to OVO or ReAmped at 25-26¢/kWh saves $300-500/year.
Understanding the NSW Default Market Offer (DMO)
The Australian Energy Regulator (AER) sets an annual DMO price cap for each NSW distribution network. This acts as a safety net — standing offers can't exceed it. For 2026-27, the DMO for a typical Ausgrid household using 3,900kWh is about $1,740/year. Market offers typically sit 10-25% below this. Every retailer's Energy Price Fact Sheet must show what percentage above or below the reference price their plan sits. If your bill doesn't display "X% less than the reference price," you're likely on a standing offer paying well above market rates. The DMO varies by network — Essential Energy customers face a higher reference price due to the cost of servicing regional areas. Check your bill for the reference price comparison and treat it as your benchmark: any plan more than 5% above the reference price should be replaced immediately.
Seasonal Electricity Usage in NSW
Summer (Dec-Feb)
Air conditioning dominates summer bills. Western Sydney suburbs like Penrith and Richmond regularly hit 40 degrees plus. A ducted system running 6 hours daily can add $300-400 to a quarterly bill. Set your thermostat to 24 degrees — each degree lower adds roughly 10% to cooling costs. Use ceiling fans alongside your aircon; they cost 1-2 cents per hour to run versus 50-80 cents for ducted cooling. Close blinds on north and west-facing windows during the day to block radiant heat before it enters your home.
Winter (Jun-Aug)
Heating drives winter bills in the Southern Highlands, Blue Mountains, and Canberra-adjacent areas. Reverse-cycle air conditioners are 3-4 times more efficient than portable electric heaters. A $30 fan heater running 5 hours daily costs $60-80/month — a split system heating the same space costs $15-25/month. Newcastle and coastal areas have milder winters but higher humidity; use dehumidifier mode on your split system rather than full heating to cut consumption by 30-40% while staying comfortable.

How to Compare NSW Plans Beyond the Headline Rate
A low usage rate means little if the daily supply charge is high. For a household using 15kWh/day, a plan at 25 cents/kWh with a $1.10 daily charge costs $1,820/year — while a plan at 27 cents/kWh with an 85 cent daily charge costs $1,788/year. The higher-rate plan actually saves $32 per year. Always calculate total annual cost using your actual usage from your last four bills. Divide your quarterly kWh by 90 to get daily average, then multiply: (daily kWh times usage rate) plus daily supply charge. Then compare across plans. The Energy Made Easy website at energymadeeasy.gov.au lets you upload a PDF of your bill and auto-calculates the best plan for your actual usage pattern — far more accurate than guessing from advertised headline discounts.
Regional NSW Warning
Essential Energy customers in rural NSW have fewer providers to choose from and rates typically 2-4 cents/kWh higher than metro areas. Regional households often benefit more from solar because daytime usage aligns with generation — particularly farms and home-based businesses. If you are on Essential Energy, check Ampol Energy and EnergyAustralia — they consistently offer the most competitive regional rates in 2026. Also verify you are receiving the Regional FiT minimum where applicable.
