How to Choose the Best Electricity Plan for Your Large Office

Choosing the right electricity plan for your big office can save you money and energy. New South Wales has so many options in deregulated markets, you need to know your office’s needs, usage patterns and the different types of electricity plans. This will walk you through the steps and considerations to help you choose the right Electricity Plan for Large Office in Adelaide.

Understand Your Office’s Electricity Usage

Before we get into plans, you need to know your office’s electricity usage. This means:

  1. Monthly Usage Patterns: How much does your office use each month, especially during peak hours. This will help you choose a plan that matches your usage patterns​
  2. Peak and Off-Peak Usage: Can your office shift heavy usage to off-peak hours to take advantage of time-of-use plans​
  3. Demand Charges: Big offices have demand charges based on peak usage. Knowing these charges will impact your plan choice.

Knowing your Adeliade office’s electricity consumption is the starting point for choosing the right plan. Big offices have more complex usage patterns than small businesses, with many variables like number of employees, types of equipment used and operating hours. Start by reviewing your electricity bills from the past year to see the trends and peak usage periods.

Load Profile Analysis

A load profile analysis will give you a detailed view of your office’s energy usage throughout the day and year. This will show you the high and low demand periods so you can choose a plan that matches your needs. For example, if your office has high usage during the day and low usage at night, you might benefit from a plan that has lower rates during off-peak hours.

Energy Audits

An energy audit will further refine your understanding of your office’s energy needs. An audit will identify energy inefficiencies and potential savings opportunities like upgrading to energy efficient lighting or HVAC systems. These improvements will reduce overall consumption and may get you better contract terms with energy providers​.

Types of Electricity Plans

Adelaide Electricity plans fall into three categories: fixed-rate, variable-rate and indexed plans. Each has its pros and cons.

Fixed-Rate Plans

Fixed-rate plans lock in a price per kilowatt-hour (kWh) for the duration of the contract, usually 12 to 36 months. These plans offer stability and predictability, so budgeting is easier. It is good for offices with steady energy usage and those who want protection against market volatility​.


  • Budget Control: Fixed rates mean steady bills for your office.
  • Protection from Price Spikes: These plans protect your office from price jumps.


  • Higher Costs: If prices drop you’ll pay more than the current rate.
  • Contract Terms: Fixed rates come with longer contracts which may not be good if your office changes.

Variable Plans

Variable plans have prices that change with the market. While they can be lower during low demand periods, they can also be higher during high demand periods. These plans offer flexibility and are good for offices that can handle some price volatility in their electricity costs.


  • Savings: You can get lower rates when prices fall.
  • Flexibility: These plans usually have shorter contract terms, so you can switch plans as needed.


  • Price Volatility: Bills can fluctuate monthly, making budgeting harder.
  • Higher Risk: There can be big price increases during peak demand periods.

Indexed Plans

Indexed plans are tied to an index such as natural gas prices. These plans can be lower when the index is low but higher if the index rises. It is good for offices that can manage their usage and market conditions​.

Pros of Indexed Plans

  • Cost Savings: Indexed plans can be lower if the linked index stays low.
  • Market-Based Pricing: These plans reflect true market conditions so they can be fairer over the long term.

Cons of Indexed Plans

  • Complexity: Understanding and predicting market indexes can be tough.
  • Higher Prices: Prices can jump if the index rises and bills get higher.

Key Considerations

Contract Term

Electricity plans can have very different contract terms. Long term (over 12 months) plans usually have more stable rates but higher early termination fees. Short term plans offer more flexibility but may have higher rates over time. How stable is your office, and can you commit to a provider for a set period.

Fees and Penalties

Watch out for:

  • Early Termination Fees: Fees for cancelling before the term ends.
  • Monthly Minimums: Some plans have a minimum usage per month which can be expensive if you use less than that.
  • Demand Charges: For big offices, these can be a big part of the bill and vary depending on the provider and plan.

Renewable Energy

Many providers offer plans with a percentage of renewable energy. These plans support your company’s green goals and may have incentives. Compare the cost and benefits of a green energy plan.

Value-Added Features

Some plans come with extra features like energy management tools, smart thermostats or rewards programs. These add value and help you manage your office’s energy usage better.

Provider Reputation

Check the provider’s reputation. Look up reviews and ratings from other businesses to ensure good service. A good provider gives you peace of mind and better customer service.

Buying Electricity Plans

Use Online Comparison Tools

Websites like Connet Market let you compare plans based on your office’s usage. These platforms include all fees and show you the total monthly cost for each plan so you can make a decision.

Online comparison tools make it easy by letting you input your office’s energy usage and compare multiple plans at once. They factor in all costs – delivery charges and fees – so you get a clear comparison.

Get Professional Advice

For big offices, working with an electricity broker or consultant can give you personalized advice and access to plans that aren’t available through standard comparison sites. Brokers can help you navigate complex contracts and get better terms​.

Avoid High-Pressure Sales

Be wary of cold calls or door-to-door salespeople offering electricity plans. These tactics usually mean higher prices and worse terms. Take your time to research and compare plans through reputable sources​.

Making Your Choice

Once you’ve compared plans and considered the above, choose the plan that suits your office best. Make sure you read all the contract details before signing. Many electricity  providers in adelaide have a cooling off period where you can change your mind within a few days of signing up without penalty, so use this if needed​.

Reviewing the Contract

Before you finalize your decision review the contract thoroughly. Look for any hidden fees or clauses that might impact your total cost. Check:

  • Renewal Terms: What happens when your contract ends? Some plans auto-renew at higher rates.
  • Service Level Agreements: Does the provider guarantee service and response times for issues?
  • Billing and Payment Options: Does the provider offer flexible billing and payment options for your office needs.


Think about how your office’s energy needs will change in the future. If you expect growth or big changes in usage patterns, choose a plan that’s flexible. Review your energy usage and contract terms regularly to make sure your plan is still right for you.


Choosing the right electricity plan for your big office is about understanding your usage, comparing plan types, looking at contract terms and fees and potentially getting professional advice. By being methodical and using the resources available to you, you can get a plan that meets your office’s energy needs and saves you money.

By looking at your office’s specific needs and researching the options available, you can make an informed decision that supports your operational efficiency and financial well-being. Whether you want to save money, renewable energy or flexible terms, there’s a plan for you and your office to succeed in a competitive business world.
