RUTLAND, VT - Central Vermont Public Service (NYSE: CV) reported consolidated earnings of $20.4 million, or $1.74 per diluted share of common stock, for the 12 months of 2009, compared to $16 million, or $1.52 per diluted share of common stock, for the same period in 2008.

CV reported fourth-quarter 2009 consolidated earnings of $2.1 million, or 18 cents per diluted share of common stock, compared to a loss of $0.1 million, or 1 cent per diluted share of common stock, for the same period last year.

"Perhaps most significant, Moody’s Investors Service rated the company at investment grade in the fourth quarter, markedly improving our borrowing capability,” President Bob Young said.  “These ratings will allow CVPS to borrow short-term capital at lower rates than we could otherwise expect to receive, and will reduce or eliminate collateral requirements in many power purchase and power sales contracts, so this expands our options as we look to secure new power supply in the future.

“We also plan to continue to make significant capital investments in our company and Vermont’s transmission system through Transco, providing customers with good reliability and investors with a solid return,” Young said.

2009 results compared to 2008

Operating revenues decreased $0.1 million year-over-year, including a $5.5 million decrease in retail revenues, an increase of $1.4 million in the provision for rate refunds, partially offset by a $1.2 million increase in other operating revenues, and a $5.6 million increase in resale revenue.  The decrease in retail revenues resulted from lower average usage resulting from the sluggish economy, energy conservation, and the loss of three commercial and industrial customers due to plant closures, partially offset by higher average unit prices due to customer usage mix.  The provision for rate refund is related to the 2009 deferrals of over-collection of power, production and transmission costs as required by the power cost adjustment clause within our alternative regulation plan.  The over-collection of power costs is being returned to retail customers through the second quarter of 2010.  Other operating revenues increased primarily due to increased sales of transmission rights and renewable energy credits and increased wholesale rates.  Resale revenues increased due to higher volumes of excess power available for resale, partially offset by lower average market prices.

Purchased power expense decreased $7.5 million, primarily due to a $9.7 million reduction of short-term power purchases and a $3.9 million decrease in purchases from Independent Power Producers.  These reductions were partially offset by an increase in other power costs of $6.1 million.  This was primarily due to higher output at the Vermont Yankee plant in 2009 and because there were no refueling outages at the Vermont Yankee or Millstone III plants in 2009.  Other operating expenses increased $6.8 million, primarily due to a $5.7 million increase in transmission expenses due to higher rates and higher costs from Vermont Transco LLC ("Transco") for its capital projects, offset by higher NOATT reimbursements.  Other increased costs included higher regulatory amortizations of $2.2 million, primarily related to the recovery of 2008 major storm costs, higher depreciation expense of $1.3 million, higher property taxes of $1.3 million and higher reserves for uncollectible accounts of $0.5 million.  These higher costs were partially offset by a $3.8 million decrease in maintenance expenses, primarily due to lower service restoration costs.  There were several major storms in 2008, but just one major storm in 2009.

Equity in earnings of affiliates increased $1.2 million, principally due to the $3.1 million investment that we made in Transco in December 2008, and other accumulated adjustments.  Other income, net increased $2.4 million, largely due to an increase in the cash surrender value of variable life insurance policies held in trust to fund a supplemental employee retirement plan.

Fourth quarter 2009 results compared to 2008

Fourth quarter operating revenues increased $4.3 million for many of the same reasons described above.

Purchased power expense decreased $1 million for the same reasons described above.  Short-term purchases decreased $5.9 million, partially offset by an increase in other purchases of $4.8 million.

Other operating expenses increased $2 million, including a $2.4 million increase in transmission expenses, and for many of the same reasons described above.  These higher costs were partially offset by lower maintenance costs for the same reasons described above.

Equity in earnings of affiliates increased $0.3 million for the same reasons described above.

2008 Common Stock Issuance

Earnings per share for 2009 reflect the impact of the November 2008 common stock issuance. On November 24, 2008, CV issued 1,190,000 shares, resulting in net proceeds of approximately $21.3 million.  The net proceeds of the offering were used for general corporate purposes, including the repayment of debt, capital expenditures, investments in Transco and working capital requirements.  The common stock issuance decreased per-diluted-share earnings by 18 cents in 2009.  There was no significant impact to per-diluted-share earnings for the fourth quarter of 2009.

2010 Financial Guidance

CV anticipates annual 2010 earnings to be in the range of $1.55 to $1.70 per diluted share.  As part of the alternative regulation plan base rate filing approved by the Vermont Public Service Board, the company's allowed rate of return for 2010 will be 9.59 percent, down from 9.77 percent for 2009.
