Transmission Capital Planning

You may submit requests for economic development studies at any time. We will consider your requests in our next capital planning cycle

We work with stakeholders on system planning in accordance with Open Access Transmission Tariff (OATT).

Attachment K. Customers and interested parties can become a participant and request a transmission study to facilitate economic development (economic planning) to provide input to the development of our transmission capital plans.

See below for information on Attachment K planning activities, which take place periodically.

If you want to take part in the transmission capital planning process, complete the request to participate form.

Transmission studies to facilitate economic development

There are areas of B.C. where our transmission system may not be adequate, or isn't available at all, to meet the area's economic development needs. To ensure we're planning for those needs, you can apply for an economic planning study related to transmission access.

Requests for economic planning studies may be selected based on their consistency with our transmission planning parameters. Some requests may be deferred to future planning cycles.

How to make a request for an economic planning study

You must be a registered participant in the transmission capital planning process before submitting a request for an economic planning study.

An economic planning study isn't a substitute for:

• BC Hydro's transmission standard generator interconnection process (SGIP)
• The interconnection process for generator owners or independent power producers
• Transmission and distribution interconnection processes for large loads.

Specific point-to-point transmission service, generation interconnection, or load interconnection requests will be studied in accordance with existing processes under BC Hydro's OATT.

This study may require detailed modeling data, analysis of potential economic benefits and an examination of key assumptions that make the economic development viable. We'll also look at investments that could result from building, or upgrading, a transmission line.
