Hydro says fourth transmission station would be required

Newfoundland Hydro says former premier Danny Williams’ planned Glencrest development would require an additional 230-kilovolt terminal station.

In Hydro’s 2014 capital budget application, the utility — in response to a question about whether Hydro anticipates the need for a new infeed/supply point in the

St. John’s area between now and 2023 — says the requirement for a new station is dependent on several factors, including load growth in the area, the location of the load growth relative to the existing stations (Oxen Pond, Hardwoods and Holyrood) and Hydro’s ability to increase transformer capacity at existing stations.

“Using the 2013-2017 Newfoundland Power Five Year Infeed Load Forecast dated 2012-09-21 and Hydro’s 2012 long-term provincial load forecast for 2018-2031 Hydro does not foresee the need for a new 230/66 kV infeed/supply point in the St. John’s area between the present and 2023,” reads Hydro’s response in the application.

But potential large-scale developments like Williams’ Glencrest in the western part of St. John’s will have “a significant impact on the load forecast for the area and distribution of load” in the area, says the response, which notes Glencrest is estimated to be the size of the town of Gander when it’s fully developed. “Glencrest has the potential to strain existing transmission infrastructure to the point where a new 230/66 kV terminal station is warranted,” reads the response.

A spokeswoman for Hydro told The Telegram a representative would be able to discuss the load forecast and the effect of large-scale growth next week. A spokeswoman for Danny Williams said the former premier has not yet had any discussions with Hydro about the Glencrest development.
