Buildings should be constructed at minimum of 5m (16ft) from an overhead power line to ensure safety. This minimum meets the Ontario Building Code requirements and Ontario Electrical Safety Code requirements related to proximity of buildings to electrical power lines.

To begin the process of getting power to your property, complete the Electrical Requirements Summary Form at the top of this page. We will work with you to establish the best method for getting power to your site, timeframe, and costs. You can also contact the Engineering Department at engineering@miltonhydro.com  or (905) 876-4611 and ask for a consultation.

If you are building a new home or business or you are upgrading or modifying your existing service or meter location, you need a Service Layout.

The Construction Standards are posted on this page for ease of customer access. The specific standards that apply to your situation will be provided to you as part of the Service Layout process.

The customer is responsible for installing underground services including transformer base, ground loop, primary and secondary trenches, conduit, meter base/ cabinet, and primary/ secondary cables (if owned by the customer).

Milton Hydro will supply and install most primary and secondary cabling that will be owned by Milton Hydro. The Offer to Connect and Service Layout for your specific site will provide greater details of our requirements.

Generally speaking, if you construct a house more than about 90m (270ft) from the road you may require an overhead pole line or underground trenched service with transformer on property. Contact Milton Hydro’s Engineering Department to determine appropriate servicing methods for your property at engineering@miltonhydro.com.

The process for connecting a distributed energy resource project to the distribution system is outlined in the Conditions of Service. We encourage any customers interested in connecting a distributed energy resource to review these guidelines and contact our Engineering Department to discuss your project.

Customers requesting a pre-consultation with Milton Hydro about their project can complete our DER Preliminary Consultation Information Request Form (PCIR). We recommend completing the initial preliminary consultation stage prior to submitting a Connection Impact Assessment (CIA) application and making significant project investments to determine the viability of your project. Application forms can be submitted to generation@miltonhydro.com.

Thinking about reducing your electricity costs by generating your own electricity? Then you may be interested in Milton Hydro’s Net metering program. Read on to learn more about our Net Metering program for generation of 500kW or less and the steps involved.

What is Net metering?

• Net metering measures the consumption of electricity you use against the amount of electricity you generate resulting in a “net” total from which your bill is calculated.
• Net Metering is ideal for those looking to reduce electricity costs.
• Under the Net Metering Agreement, excess generation credits can be carried forward up to twelve months to offset future electricity costs.
• Applicable generation types for net metered connections include renewable energy sources such as Solar PV, wind, and water.

 

How will my bill be calculated?

Milton Hydro will continue to read your meter as we do now. The bill you see will reflect the difference between the value of the electricity you return to the grid and the value of electricity you consume from the grid. If your net consumption for a billing period is zero, or results in a credit, the delivery portion of your bill will not include kilowatt-hour-based charges and the net credit will be carried forward to the next billing cycle. Settlement of Net Metered accounts will follow O.Reg. 541/05.

Green Button provides a unified, industry-standard data format, which can be used to analyze and manage a consumer’s energy usage. The introduction of Green Button industry-standard data across Ontario utilities will provide the foundation for the development of new tools and applications for customers to analyze and monitor their energy usage to reduce costs.

Below are just a few of the benefits of Green Button data:

• Improve energy efficiency – Consumers can use Green Button data to identify and compare their energy usage in order to improve energy-efficiency within their home or business.
• Reduce energy costs -By learning their usage patterns and habits, consumers can make informed choices about how much energy they use and when they use it. When consumers use energy during off-peak hours (also known as peak-shaving) and invest in energy-efficient appliances, it saves money and can help reduce strain on the grid.
• Energy conservation –consumers can use their data to conserve energy to help reduce their carbon footprint and protect the environment.
• Green button tools to understand large volumes of energy data will help pave the way for future innovations in the energy sector.

Green Button Data for Residential and Small Commercial Customers:

• Many customers are already viewing their energy data through a customer portal on their utility website. With Green Button, third party apps can analyze the data and provide insights to help customers make sense of their energy use and make informed decisions to help reduce costs.
• With CMD, data is shared on an ongoing basis. This allows third parties to provide insights and alerts on usage trends and changes.

Green Button Data for Businesses:

• For customers with a large number of properties across multiple utilities, Green Button provides a standardized format so that the data they receive from each utility is in a similar format. Green Button third parties in the commercial sector are able to analyze large volumes of data across multiple facilities to provide energy management advice.
• With CMD, data is shared on an ongoing basis. This allows third parties to provide insights and alerts on usage trends and changes including monitoring the impact of energy efficiency measures taken.
• Green Button will also make it easier for facilities to complete mandatory government reporting requirements.
