 Bloomberg -- One of the largest utilities in America is starting to turn its back on natural gas.Dominion Energy Inc., the second-biggest U.S. power company by market value, on Sunday said its selling substantially all of its gas pipeline and storage assets to Berkshire Hathaway Inc. for 4 billion. Its the largest deal announced this year to buy U.S. energy assets, according to Bloomberg data.In a separate statement, Dominion and its partner Duke Energy Corp. said theyre killing the controversial Atlantic Coast gas pipeline along the U.S. East Coast, citing ongoing delays and cost uncertainty.The moves come as utilities face increasing pressure from local governments, investors and environmentalists to quit fossil fuels. While long heralded as a cleaner alternative to coal and heating oil, gas is drawing stiff oppositions from left-leaning state lawmakers, making it increasingly difficult to build pipelines and other infrastructure.Until these issues are resolved, the ability to satisfy the countrys energy needs will be significantly challenged, Dominion Chief Executive Officer Thomas Farrell said on a call with analysts. This trend, so deeply concerning for our countrys economic growth and energy security, is a new reality.Read More: Grim Day for Pipelines Shows Theyre Almost Impossible to BuildShares of Dominion, which also announced its cutting its dividend, fell 11 Monday, the most in more than three months. The company is taking 2.7 billion to 3.2 billion in pre-tax charges related to the canceled pipeline, it said in a filing.The push away from gas positions Dominion as more of a pure-play state-regulated utility at a time when oil and pipeline operators have lagged the broader market. In the last year, an index of pipeline companies has fallen 36, while the SP; 500 Index has gained 4.7.Given the bend towards decarbonization efforts in the country, the move away from natural gas, and investor demand for more simplified utility structures, we believe this is absolutely the correct move for Dominion to make, Guggenheim analysts led by Shahriar Pourreza said in a research note.Read More: Wall Street Falls Out of Love With Once-Coveted Fossil FuelTo be clear, Richmond, Virginia-based Dominion, which provides power and gas to seven million customers in 20 states, isnt walking away from the fossil fuel altogether. It will still sell gas to customers for heating and cooking. Its retaining an interest in its Cove Point liquefied natural gas export terminal in Maryland. And 40 of the electricity the company generates comes from plants fueled by gas, coal and oil, according to its website.Theyll still be burning lots of gas for decades ahead in the core utility business, Bloomberg Intelligence analyst Kit Konolige said in an email.But pressure is mounting. Virginia enacted a law in April requiring Dominions utility in the state to be carbon-free by 2045.What Bloomberg Intelligence SaysDominions unsurprising shutdown of the troubled Atlantic Coast Pipeline project and 4 billion sale of midstream properties take pressure off the strained balance sheet. In combination with a dividend cut, the steps shift Dominion to an almost all-utility growth story.-- Kit Konolige, senior utility analystRead the full report here.Atlantic Coast is the third U.S. gas pipeline project to scrapped or shelved this year. Williams Cos. opted not to reapply for a permit in May for a 1 billion pipeline extension after regulators in New York blocked it. And in February the Oklahoma-based company canceled plans for a pipeline that would have run from Appalachia to New York.While the Atlantic Coast pipeline project won a key victory last month when the U.S. Supreme Court sided against environmentalists and upheld a crucial permit, the project still faced formidable opposition and costs. That would indicate that that wasnt a strategic decision as much it was as a practical decision, said Paul Patterson, an analyst at Glenrock Associates LLC.Read More: Duke to Book Charge of Up to 2.5 Billion From Canceled PipelineDeal with BerkshireDominions deal with Berkshire calls for the giant conglomerate to assume 5.7 billion in debt.
