Submetering Power


Submetering power refers to the practice of using individual meters to measure the electricity usage of specific units within a multifamily building. Without this, a property owner would depend on a single electric meter, to measure the electricity usage of an entire building.
The purpose of submetering power is to accurately allocate the costs of electricity to each individual multifamily unit. This allows each unit to be billed for its electricity usage and to pay for only the electricity they consume.
Submetering power can also be used to monitor and manage the electricity usage of specific systems or equipment within a building including HVAC systems or lighting systems. By measuring the electricity usage of these systems separately, building owners can identify areas where energy efficiency improvements can be made, which can help to reduce electricity costs and improve the overall energy efficiency of the building.
Submeters can be installed and maintained by NES, which offers services such as meter installation, meter reading, billing, and customer support. NES also offers energy conservation programs and other services to help building owners and tenants reduce their electricity usage and lower their energy costs.

What is Submetering?

Submetering involves the installation of equipment to measure and bill each unit’s utility use. Submetering has been used since it was invented in the early 1920s.

What are the benefits?

If you are trying to recover operating expenses for your apartment complex, Submetering is the answer.
When a property installs utility submeters, residents work harder to conserve utilities, dramatically reducing overall consumption. Residents are also responsible for their own usage, which almost eliminates the utility expenses for the landlord.
Submetering can also increase the value of your apartment complex or mobile home park.
Bottom line: The return on the investment is usually seen within 12 months because the residents pay for the utilities they use.

All types of real estate can be submetered. We serve both new construction and existing properties, those with equipment in place and those requiring equipment.

What is RUBS and how can it help real estate that can’t be metered?

RUBS, or Ratio Utility Billing System, is a method of allocating utility costs among residents in a multi-unit property. It is typically used in properties where it is not feasible or cost-effective to install individual meters for each unit, such as older buildings or properties with shared plumbing systems.
Under a RUBS system, NES calculates the utility usage for each unit based on the total utility usage for the property. This is based on factors such as the number of occupants, the number and type of appliances, and the property’s square footage. The total cost is then divided among the individual units according to a predetermined ratio.
RUBS can help real estate that can’t be submetered by providing a fair and equitable way to allocate utility expenses among residents. It can also help reduce utility waste and improve the property’s overall energy management.

Does Submetering have regulations?

Yes, submetering is regulated by various state and local laws. These regulations typically govern issues such as the installation and maintenance of submeters, the accuracy of the meters, and the billing of residents for their utility usage. The regulations governing submetering can vary depending on the location and type of property, so it is important for property owners or managers to familiarize themselves with the relevant laws in their area if they choose to submeter without NES.
