Battery Storage


The next wave of cutting-edge technology is home battery storage.

A home battery storage system stores energy in two ways. If your home has an alternative energy source like solar panels, the energy generated can be captured and stored in the home battery storage system to use later. Alternatively, the home battery storage system can charge directly from the grid, such as during off-peak hours when our Time-of-Day (TOD) rates are lower. The battery can provide energy during peak hours when rates are higher to offset your electricity costs. The battery can also be used as a backup power source in the event of an outage.

Please note that battery storage alone is not eligible for the TOD rate but your home can take advantage of the TOD rate if a thermal storage heating system is already installed in the home.

MPOWER Energy Solutions is working with us to supply and install Tesla Powerwalls.

Here is how MPOWER battery storage works in your home:

Backup


MPOWER MPOWER

Assures power in the event of a grid outage. This scenario applies to the majority of homes in Nova Scotia today.

Solar

Charge the MPOWER Solution with excess energy from solar panels during the day for use at night.

Load shifting - Powerwall charges during low rate periods when demand for electricity is lower and discharges during more expensive rate periods when electricity demand is higher. Note: battery storage alone is not eligible for the time-of-use rate but your home can take advantage of the time-of-use rate if a thermal storage heating system is already installed in the home.

Testing battery storage in Elmsdale

The Intelligent Feeder Project involves residential energy storage batteries (Tesla Powerwalls) installed at 10 homes in the Elmsdale community and a much larger grid-sized battery (Tesla Powerpack) at the Elmsdale substation. These batteries are connected to an electrical line powered, in part, by the nearby Hardwood Lands wind turbines. Sensors on the powerline monitor and gather data about local system activity and are fed back to our control centre for analysis and planning of Nova Scotia’s future energy needs.

FAQS:


Will my generator work with a smart meter?

Smart meters will not impact household generators, so long as the generator is properly connected. More information about generator installation and safety can be found on Nova Scotia Power’s web site.

Have smart meters been activated and is the network on?

All smart meters begin communicating at the time of installation. While smart meters are active, we continue to build the smart meter communications network in preparation for turning the customer facing benefits of smart meter technology on in early 2021. These benefits include:

  • Access to daily information on your energy usage and notifications, helping you make more informed decisions and manage your electricity costs.
  • Connecting or disconnecting your electricity will be easier and faster with no on-site appointment required.
  • Smart meters will notify us when your power goes out, helping us respond more quickly in the event of an outage.

Will smart meters transmit data all day?

Our smart meters will collect power consumption data every 15 minutes and transmit this data back to Nova Scotia Power via a secure connection four times a day. We expect the duty cycle — the total time meters are transmitting — to be very brief, representing an average of 0.21% in a 24-hour period (approximately three minutes per day). This estimate reflects studies in other jurisdictions using similar technology.  

What will you do with my energy usage data? Is it kept private?

Nova Scotia Power takes the privacy of customer information very seriously. We do not sell personal information and only share it with third parties in limited circumstances in order to provide services to customers. For example, e-billing and credit card transactions are managed by third parties (financial institutions). We also use third parties to collect payments and process data on our behalf.

The steps we take to protect customer information is specified in our privacy policy.

What are the environmental benefits of using smart meters?

Smart meters will allow us to provide customers with faster, more effective service and keep rates stable. While we’re committed to a clean energy future, we have not made any specific commitments relating to the environmental benefits of smart meters. However, given the ability to monitor energy use more frequently and in greater detail, we expect many customers will turn off unneeded appliances, change to more efficient lighting, adjust thermostats and make other energy-saving changes that save money and reduce emissions. In addition, smart meters reduce emissions associated with performing services such as connections, disconnections and meter readings where vehicles are required.

 Smart meters also provide the foundation for a new, and smarter, energy grid that will enable more wind and solar generation, battery storage and electric vehicles. A modern power grid is more energy efficient which helps manage costs while also acting as a catalyst for a cleaner environment.

 

Is the east coast environment inhospitable to smart meters?

We’re confident that smart meters can operate safely and effectively in Nova Scotia. A life test report on the smart meter we use, the OpenWay Riva Centron, was filed with the Nova Scotia Utility and Review Board. This report examined operational performance in various conditions including issues relating to moisture infiltration.

It is normal to have a small amount of moisture condensate with-in the cover of any type of meter including an old analog or new smart meter, especially at times of the year where temperature fluctuations are common. This will normally dry up quickly on a warm day. If a customer feels it is excessive, they should contact our Customer Care Centre at 1.800.428.6230 and they would be happy to assist and send a crew to investigate if necessary.
