Berkshire Hathaway's Nevada utility company NV Energy is doubling down on efforts to boost its renewable generation resources in order to ensure that projects qualify for tax incentives. The company announced this week that it would be seeking bids for 200 megawatts of renewable projects within a month, following an order from the Nevada Public Utilities Commission that urged the company to move faster because of uncertainty over incentives like the investment tax credit which will be reduced at the end of 2016.
