Brad Jones, interim CEO of the Electric Reliability Council of Texas (ERCOT), announced his support for Bitcoin. "I support Bitcoin... but I'm too risk-averse to be an investor in Bitcoin." It is reported that ERCOT provides electricity to about 90% of the state. Brad Jones pointed out that Bitcoin mining in the state could be beneficial to both Texas and the Bitcoin network. Bitcoin mining and Texas can establish a mutually beneficial relationship. This is because Bitcoin miners require a lot of energy, and the state is able to provide energy at very competitive prices. Power output is even expected to increase as the company plans to integrate large amounts of renewable energy generation into the grid. He pointed out that Bitcoin miners can consume this excess power supply when demand is low. Texas Congressman Ted Cruz has the same view. (Zycrypto)

Iceland’s power shortage has caused the island’s main utility, Landsvirkjun, to reduce supply to some industrial customers, such as fishmeal factories, aluminum plants and data centers. The company said Tuesday that it had also rejected all requests for power from new cryptocurrency mining customers. Landsvirkjun cited low reservoir levels, power station failures and delays in getting power from outside producers as reasons for the move, which is effective immediately. Iceland’s biggest electricity consumers are giant smelters built decades ago that have benefited from cheap electricity, while more recent entrants into the country’s market are cryptocurrency miners. Companies such as Canada’s Hive Blockchain Technologies Ltd., Hong Kong-listed Genesis Mining Ltd. and Bitfury Holding BV have all opened mining operations in Iceland. (Bloomberg)
