April 26 (Reuters) - Keith Anderson , chief corporate officer of Scottish Power, a unit of Iberdrola SA, said on Wednesday:
* A potential energy price cap proposed by the British government would harm competition and it should set a deadline to abolish standard variable tariffs (SVTs) instead.
* "The government could impose a target that two out of three customers should be on a deal by the end of 2018, and all customers on a deal by the end of 2019, with SVTs abolished once and for all," Anderson said.
* "Any company that fails to meet these targets should have a price cap not only imposed but retained until all their customers are on deals."
* The government has set out plans to hold down the prices households pay for gas and electricity which have doubled in the last decade. Further company coverage: (Reporting by Nina Chestney; editing by Jason Neely)
