What is Available Supply Capacity (ASC)?
Available Supply Capacity (ASC) refers to the maximum amount of electricity that a business can draw from the power grid at any given time. ASCÂ is measured in kilovolt-amperes (kVA) and is agreed upon between the business and the energy supplier.Â
The ASC is crucial for ensuring that a business’s electrical needs are met without overloading the local power network. Managing ASC effectively helps businesses avoid excessive demand charges and ensures they have sufficient power for their operations, while also providing room for future expansion or increased energy usage.
At Consultiv Utilities, we help businesses understand their energy usage and set up optimised agreements between the business and the supplier to avoid costly bills in the future.Â
What is kVa for a Capacity Charge Analysis?
Kilo volt-amperes, or kVa for short, is a measure of the total amount of electricity being used on site. This metric is used by your energy supplier to bill you for your energy usage within your agreed terms. If this limit is exceeded, then you may be charged additional fees for going above your agreement.Â
At Consultiv Utilities, we renegotiate this agreement to allow your business to avoid these costly fees, allowing you to focus your finances on growing your business.Â
What happens if you exceed your kVA?
If a business exceeds its agreed-upon kVA, several consequences can occur:
- Penalty charges: The energy supplier may impose extra charges or penalties for surpassing the set ASC, which can increase operational costs.
- Overloading risks: Exceeding kVA limits can strain the electrical infrastructure, potentially leading to equipment malfunctions or failures.
- Supply disruptions: Persistent overuse may cause supply disruptions or outages, affecting business operations.
- Need for upgrades: The business may need to renegotiate the ASC with the supplier or upgrade its electrical infrastructure to accommodate higher demand, which can incur additional costs and logistical challenges
Reducing and increasing your Available Supply Capacity (ASC)
You may wish to reduce your ASC because you are not getting close to your limit. This could be because you have a high ASC compared to your usage or because you have implemented energy efficiency on-site and no longer consume as much electricity. Our team can help liaise with your energy supplier to adjust your ASC, ensuring it aligns with your specific needs.
Conversely, you may wish to increase your ASC if you need to consume more or are consuming more than in the past and are being hit with charges relating to overconsumption. We can support you in negotiating with your energy supplier to formally increase your ASC, ensuring it supports your business growth or increased energy requirements.Â
FAQs
What is Capacity Charge Analysis, and why is it important for my business?
Capacity Charge Analysis helps ensure that your business is not paying for more electricity capacity than it needs. By reviewing your historical energy data and comparing it to your Available Supply Capacity (ASC), Consultiv Utilities can identify if your kVA level is set correctly, helping to reduce unnecessary costs and improve energy efficiency.
How does Available Supply Capacity (ASC) affect my electricity bill?
Your ASC determines the maximum amount of power your site can draw at any one time. If this is set too high, you may be overpaying for unused capacity; too low, and you risk exceeding limits and triggering penalty charges. Our Capacity Charge Analysis service ensures your ASC aligns perfectly with your site’s operational demand.Â
What does kVA mean in energy management?
kVA, or kilovolt-amperes, measures the apparent power your business uses. It represents both the active (useful) and reactive (wasted) power in your electrical system. Managing your kVA effectively helps prevent inefficiencies, reduce reactive power charges, and optimise your energy supply contract.
Can Consultiv Utilities help adjust my ASC with my energy supplier?
Yes. Our consultants liaise directly with your energy supplier to negotiate ASC increases or reductions on your behalf. This ensures your electricity capacity is right for your current and future energy needs, reducing excess costs and supporting business growth.
What happens if my business goes over its ASC?
Going over your ASC can result in additional demand charges, infrastructure strain, or even supply disruptions. Consultiv Utilities monitors and analyses your usage data to prevent these issues and help you renegotiate your ASC before costly overuse penalties occur.
How often should a Capacity Charge Analysis be carried out?
We recommend reviewing your capacity charges annually or after any major operational change, such as new equipment, expansion, or improved energy efficiency. Regular analysis ensures your ASC remains accurate and cost-effective over time.
What type of businesses benefit most from Capacity Charge Analysis?
High-consumption sites such as manufacturing plants, warehouses, data centres, and large commercial offices benefit most from Capacity Charge Analysis. However, any organisation seeking to optimise energy costs and usage can benefit from this service. If you have received penalties for overuse, or you are concerned that your business’s operation may incur additional charges, then speak with Consultiv Utilities by using the contact form above, and we will get you on the right path with your supplier.Â
Does reducing my ASC affect my energy supply or performance?
No. When done correctly, reducing your ASC simply aligns your maximum capacity with your actual demand. Consultiv Utilities ensures any adjustments maintain your operational requirements while reducing excess capacity costs. We do this by carrying out a review of your demand with a Capacity Charge Analysis, and then renegotiate your contract with your supplier or recommend that you change your supplier based on this data, and on which price works best for your business.
