Charlottetown Generating Station (CTGS) is a diesel generating station owned by Maritime Electric, located on Cumberland Street in Charlottetown, Prince Edward Island. As of December 2024, the CTGS property consists of 14 parcels of land and 4 water lot parcels measuring approximately 11.65ha (28.8 acres) and contains the following infrastructure:[1]
energy control centre
substation for downtown and east side of Charlottetown
The CTGS property has developed in phases through various previous owners:
1854–1900 (approximately) saw the property developed by the Charlottetown Gas Light Company to produce coal gas with coal delivered by railcar by the Prince Edward Island Railway. The coal gas was then distributed throughout the city by pipes underneath the street to light streetlights. Charlottetown Gas Light Company was purchased by Charlottetown Light & Power Company in 1898.[1]
1900–1926 saw electricity generation begin on the property around 1900 when a Corliss reciprocating steam engine and generator were relocated from a decommissioned generating station at the corner of Water Street and Pownal Street in Charlottetown. Coal gas continued to be produced as well. Fredericton- based Maritime Electric purchased Charlottetown Light & Power Company, resulting in the property being controlled by the current (as of December 2024) owner.[1]
1926–1931 saw the property redeveloped, beginning with the removal of the Corliss engine, generator and coal gas equipment. Three coal-fired boilers and steam turbines were installed over a 5 year period, creating what came to be known as the "steam plant."[1]
From 1943–1976 the property continued to be developed with additional units (Nos. 4-10) being added over this period, along with the conversion from coal to Bunker C fuel oil. Boilers and generators were consolidated to 5 units with an installed capacity of 60 MW. The entire facility was converted to Bunker C fuel in 1959-1960 and construction of the distinctive twin chimneys that towered over the Charlottetown waterfront.[1]
1977年から2005年にかけて、CTGSの蒸気発電所はオンデマンド電源に戻った。CTGSは、 1977年にノーサンバーランド海峡の下に2本の海底ケーブル(2 x 100 MW)が設置され、マリタイム・エレクトリックとNBパワーの最初の相互接続が実現するまで、プリンスエドワード島の主要な電力源であった。このケーブルは、プリンスエドワード島のファーンウッドからニューブランズウィック州のマレーコーナーまで伸びていた。1977年以降、CTGSの蒸気発電所は、主にピーク需要時またはニューブランズウィックからの電力供給が阻害されたときに使用された。[ 3 ]
