NU REPORTS FOURTH QUARTER, YEAR-END 2009 RESULTS, AFFIRMS 2010 EARNINGS GUIDANCE

HARTFORD, Connecticut, February 23, 2010 – Northeast Utilities (NYSE:NU) today reported earnings for the fourth quarter of 2009 of $84.7 million, or $0.48 per share, compared with $71.9 million, or $0.46 per share, in the fourth quarter of 2008.  NU earned $330 million, or $1.91 per share, in 2009, compared with $260.8 million, or $1.67 per share, in 2008.  

Full year results for 2008 included an after-tax charge of $29.8 million, or $0.19 per share ¹, associated with the settlement of litigation in the first quarter of 2008.  Excluding that charge, NU earned $290.6 million, or $1.86 per share ¹, in 2008.  

NU’s earnings per share rose by approximately 2.7 percent for the full year of 2009, compared with the same period of 2008, excluding the impact of the 2008 litigation charge.  Both fourth quarter and full year 2009 earnings per share levels reflect the issuance of nearly 19 million additional NU common shares in March 2009.  

“We are pleased with our overall performance in a difficult economy in 2009,” said Charles W. Shivery, NU’s chairman, president and chief executive officer.  “However, while the other segments of our company performed well, the financial results of our four distribution businesses continued to be disappointing.  Those businesses were clearly weakened by economic factors, even though we maintained tight control of our operating costs and continued to invest in the energy infrastructure needed to serve our customers and our region.”

NU’s retail electric sales declined 3.5 percent in 2009, compared with 2008.  They were down 2.1 percent on a weather-adjusted basis.  Fourth quarter retail electric sales were down 2 percent in 2009, compared with 2008.  They were down 1.7 percent on a weather-adjusted basis.  Yankee Gas Services Company firm natural gas sales were up 3.8 percent in the fourth quarter of 2009, compared with the same period of 2008.  They were up 5.8 percent on a weather-adjusted basis.  For all of 2009, Yankee Gas firm sales were up 6.9 percent compared with the full year of 2008, and up 5 percent on a weather-adjusted basis.

2010 earnings guidance

Today NU affirmed its 2010 earnings guidance of between $1.80 per share and $2.00 per share.  The guidance reflects projected 2010 distribution and generation segment earnings of between $0.95 per share and $1.05 per share ¹; transmission segment earnings of between $0.90 per share and $0.95 per share¹; competitive business earnings of between $0.00 per share and $0.05 per share ¹; and NU parent and other expenses of approximately $0.05 per share¹.

2009 Results - Transmission

NU’s transmission segment earned $44.4 million in the fourth quarter of 2009, compared with $34.7 million in the fourth quarter of 2008, and $164.3 million for the full year of 2009, compared with $138.3 million for the full year of 2008.  The increases in fourth quarter and full year net income in 2009, compared with the same periods of 2008, primarily reflect NU’s increased investment in transmission infrastructure.

2009 Results - Distribution and Generation

NU’s distribution and generation segment earned $39.2 million in the fourth quarter of 2009, compared with $36 million in the fourth quarter of 2008, and $159.2 million for the full year of 2009, compared with $150.8 million for the full year of 2008.

The Connecticut Light and Power Company’s (CL&P) distribution segment earned $19 million in the fourth quarter of 2009, compared with $12.8 million in the fourth quarter of 2008 and $74 million for the full year of 2009, compared with $70 million for the full year of 2008.  Improved fourth quarter results were due in part to the absence of a $3.5 million after-tax charge that CL&P recorded in the fourth quarter of 2008 related to a regulatory decision concerning 2004 power procurement.  Full year 2009 results reflect the benefit of a distribution rate increase that took effect in February 2009 and lower operating and storm costs largely offset by a 3.8 percent decline in retail sales, higher depreciation, pension and tax expense, and the impact of higher uncollectible customer accounts.  CL&P’s distribution regulatory return on equity (ROE) for 2009 was 7.3 percent, well below its current authorized level of 9.4 percent.

Public Service Company of New Hampshire’s (PSNH) distribution and generation segment earned $11.3 million in the fourth quarter of 2009 and $47.5 million for the full year of 2009, compared with $9.1 million in the fourth quarter of 2008 and $41.4 million for the full year of 2008.  Higher generation-related earnings and a temporary distribution rate increase effective August 1, 2009, were partially offset by higher operation, depreciation, pension and tax expense.  PSNH’s distribution regulatory ROE for 2009, excluding earnings on PSNH generating facilities, was approximately 3.6 percent, compared with its current authorized level of 9.67 percent.

Both CL&P and PSNH have filed with their respective state regulators for increases in distribution rates, and decisions are expected in mid-2010.  “These cases are critical in our efforts to achieve reasonable returns on the significant investments NU shareholders have made in the electric distribution infrastructure of Connecticut and New Hampshire,” Shivery said.

Western Massachusetts Electric Company’s (WMECO) distribution segment earned $3.2 million in the fourth quarter of 2009 and $16.7 million for the full year of 2009, compared with $2.2 million in the fourth quarter of 2008 and $12.3 million for the full year of 2008.  Improved full year 2009 results were largely due to the absence of charges WMECO recorded in 2008. WMECO’s distribution regulatory ROE was 8.4 percent in 2009.

Yankee Gas earned $5.7 million in the fourth quarter of 2009, compared with $11.9 million in the fourth quarter of 2008.  Yankee Gas earned $21 million for the full year of 2009, compared with $27.1 million for the full year of 2008.  Lower fourth quarter and full year 2009 results were primarily due to higher expense related to uncollectible customer accounts.  That expense was $4.4 million higher on an after-tax basis in the fourth quarter of 2009 and $6.9 million higher on an after-tax basis for the full year of 2009, compared with the same periods of 2008.  Yankee Gas’ regulatory ROE was 6.6 percent in 2009.

2009 Results - Competitive businesses

NU Enterprises, Inc. (NUEI), the holding company for NU’s competitive businesses, earned $4.2 million in the fourth quarter of 2009, compared with earnings of $4.3 million in the fourth quarter of 2008.  NUEI earned $15.8 million for all of 2009, compared with earnings of $13.1 million for all of 2008.  The improved results reflect stronger operating margins and the absence of a $3.2 million net charge in 2008

$29.8 million litigation charge.

¹ All per share amounts in this news release are reported on a fully diluted basis.  The only common equity securities that are publicly traded are common shares of NU parent.  The earnings and EPS of each business do not represent a direct legal interest in the assets and liabilities allocated to such business, but rather represent a direct interest in NU's assets and liabilities as a whole.  EPS by business is a non-GAAP (not determined using generally accepted accounting principles) measure that is calculated by dividing the net income or loss attributable to controlling interests of each business by the weighted average fully diluted NU parent common shares outstanding for the period.  Management uses this non-GAAP financial measure to evaluate earnings results and to provide details of earnings results and guidance by business.  Management believes that this measurement is useful to investors to evaluate the actual and projected financial performance and contribution of NU’s businesses.  This release references NU’s 2008 earnings and EPS excluding a significant charge associated with a litigation settlement payment, which are non-GAAP measures.  Due to the nature and significance of the litigation charge, management believes that this non-GAAP presentation is more representative of NU’s performance and provides additional and useful information to readers of this news release in analyzing historical and future performance.  These non-GAAP financial measures should not be considered as alternatives to NU consolidated net income attributable to controlling interests or EPS determined in accordance with GAAP as indicators of NU’s operating performance.
