Noncontrolling Interest [Abstract]
IMPAIRMENT OF EQUITY INVESTMENTS	IMPAIRMENT OF EQUITY INVESTMENTS PennEast Pipeline Company, L.L.C. PennEast Pipeline Company, L.L.C. (PennEast) is a joint venture formed to develop a natural gas transmission pipeline to serve local distribution companies and power generators in Southeastern Pennsylvania and New Jersey, is owned 20% by Enbridge, and is recorded as an equity method investment. During the three months ended September 30, 2021, PennEast determined further development of the project was no longer viable and further development of the project has ceased. As a result, we recorded an other than temporary impairment loss of $111 million on our investment for the three and nine months ended September 30, 2021 based on the estimated fair value of our share of the net assets. The carrying value of this investment as at September 30, 2021 and December 31, 2020 was $11 million and $116 million, respectively. Steckman Ridge, LP Steckman Ridge, LP (Steckman) is engaged in the storage of natural gas, is owned 50% by Enbridge, and is recorded as an equity method investment. In the third quarter of 2020, Steckman’s forecasted performance was adjusted for the expectation that future available capacity will be re-contracted at lower than expected rates and an other than temporary impairment loss on our investment of $221 million for the three and nine months ended September 30, 2020 was recorded based on a discounted cash flow analysis. The carrying value of this investment as at September 30, 2021 and December 31, 2020 was $88 million and $90 million, respectively. Southeast Supply Header, L.L.C. Southeast Supply Header, L.L.C. (SESH) provides natural gas transmission services from east Texas and northern Louisiana to the southeast markets of the Gulf Coast. SESH is owned 50% by Enbridge and is recorded as an equity method investment. In the third quarter of 2020, SESH's forecasted performance was revised to reflect downward revisions to future negotiated rates as well as higher than expected available capacity levels, caused primarily by a significant contract expiry. An other than temporary impairment loss on our investment of $394 million for the three and nine months ended September 30, 2020 was recorded based on a discounted cash flow analysis. The carrying value of this investment as at September 30, 2021 and December 31, 2020 was $83 million and $84 million, respectively. DCP Midstream, LLC DCP Midstream, LLC (DCP Midstream), a 50% owned equity method investment of Enbridge, holds an equity interest in DCP Midstream, LP. A decline in the market price of DCP Midstream, LP’s publicly traded units during the first quarter of 2020 resulted in an other than temporary impairment loss on our investment in DCP Midstream of $1.7 billion for the nine months ended September 30, 2020. In addition, we incurred losses of $324 million through our equity earnings pick up in relation to asset and goodwill impairment losses recorded by DCP Midstream, LP during the nine months ended September 30, 2020. The carrying value of our investment in DCP Midstream as at September 30, 2021 and December 31, 2020 was $298 million and $331 million, respectively. Our investments in PennEast, Steckman, SESH, and DCP Midstream form part of our Gas Transmission and Midstream segment.
