www.pnmresources.com - PNM Resources Gina Jacobi, 505-241-2211 (Analysts) Frederick Bermudez, 505-241-4831 (Analysts & Media) PNM Resources' (NYSE: PNM) New Mexico electric utility, PNM, today filed for an increase in general rates of $123.3 million - an increase in revenue of 18 percent.

If approved by the N.M. Public Regulation Commission, the proposed increase is expected

to go into effect in August 2009. With the proposal, PNM electric rates are projected to be 17 percent below the regional average and 13 percent below the national average.

"New Mexico's economy and its population are growing rapidly, and so is its need for more electricity," said Pat Vincent-Collawn, PNM Resources president and chief operating officer. "These proposed rates are part of our larger effort to prepare for New Mexico's energy future and ensure that PNM is financially healthy so that it can provide new sources of power, continue to reduce emissions and increase its investment in renewable energy."

Filed today with the Commission, PNM's request includes:

-- The continued use of a fuel and purchased power cost adjustment clause, which includes a proposal for a 75-25 sharing of off-system sales margins, with 75 percent going to customers. Profits from off-system power sales would reduce the overall increase request.

-- The recovery of the costs associated with the environmental improvement project at the San Juan Generating Station. PNM is seeking recovery of incurred costs already made on units 3 and 4 and an out-of-period adjustment for the projected investment of $81.7 million related to improvements on units 1 and 2, which will be completed about the same time the new rates would take effect.

-- A return on equity of 11.75 percent, based on a rate base of $1.6 billion and a test period revenue requirement of $807.4 million.

Earlier this month, PNM filed an agreement with key parties that would allow the utility to recover the costs of adding 357 megawatts to its retail generation portfolio and acquiring the beneficial interests of 29.8 megawatts of Unit 2 of the Palo Verde Nuclear Generating Station that the company previously leased. Adding those resources to PNM's rate base accounts for nearly 36 percent of the requested annual rate increase. The agreement - or stipulation - also needs Commission approval.
