Energy Efficiency Implementation Rates

The PUCN's final order approving the merger between Berkshire Hathaway Energy and NV Energy stipulated that the Company will not seek recovery of any lost revenue for calendar year 2014 in an amount that exceeds 50% of the lost revenue that the Company could otherwise request. As a result, the Company has deferred revenue recognition for energy efficiency implementation rates collected and has recorded a liability of $2 million on the Consolidated Balance Sheets as of March 31,2014. In February 2014, the Company filed an application with the PUCN to reset the energy efficiency implementation rate. The Company proposed to suspend collection of the energy efficiency implementation rate on October 1, 2014, and defer implementation of a new energy efficiency implementation rate until January 1, 2015.

2013 FERC Transmission Rate Case

In May 2013, the Company, along with Nevada Power, filed an application with the FERC to establish single system transmission and ancillary service rates. The combined filing requested incremental rate relief of $17 million annually to be effective January 1, 2014. On August 5, 2013, the FERC granted the companies' request for a rate effective date of January 1, 2014 subject to refund, and set the case for hearing or settlement discussions. On January 1, 2014, the Company implemented the filed rates in this case subject to refund as set forth in FERC's order. As of March 31,2014 the Company accrued $1 million for amounts subject to rate refund, which is included in customer deposits and other on the Consolidated Balance Sheets. At this time management is unable to determine the final revenue impact of the case.
