Exhibit 99.1

     Mpower to Reshape Company through Strategic and Financial Transactions


ROCHESTER, NY - January 8, 2003 - Mpower Communications Corp. (NASD OTC: MPOW),
a provider of integrated data and voice services to business customers, today
announced several strategic and financial transactions which should further
strengthen the company financially and focus its operations on its California,
Nevada and Illinois markets.

Mpower has reached an agreement with RFC Capital Corporation, a wholly owned
subsidiary of Textron Financial Corporation, for a three-year funding facility
of up to $7.5 million, secured by certain of the company's receivables. Mpower
anticipates closing this facility by January 31, 2003. This new funding is
expected to provide near-term liquidity for Mpower as it continues to
restructure its operations. The company indicated that it is also in active
discussions with additional potential investors.

         Mpower is bringing geographic concentration to its business by
transitioning its customers and assets in Florida, Georgia, Ohio, Michigan and
Texas to other service providers. Each of these transactions is expected to
result in cash infusions to Mpower and significant reductions to the company's
cost structure. Importantly, these transactions are expected to provide
uninterrupted service for customers transitioning from Mpower and job
opportunities for the company's employees in these markets.


o    Mpower has reached an agreement for its Southeast markets, and will
     transition its customers in Atlanta, Ft. Lauderdale, West Palm Beach, Miami
     and Tampa to Orlando-based Florida Digital Network Inc., a full-service
     integrated communications provider.

o    Mpower has also reached an agreement for its Texas markets, and will
     transition its customers in Dallas/Ft. Worth, Houston, Austin and San
     Antonio to Xspedius Equipment Leasing, an affiliate of Xspedius
     Communications, a competitive communications carrier headquartered in St.
     Louis.

o    Finally, Mpower also reached an agreement for its Michigan and Ohio
     markets, and will transition its customers in Detroit, Cleveland and
     Columbus to LDMI Telecommunications, an integrated communications provider
     serving primarily business customers in the Great Lakes region.

Twelve months ago, Mpower set out on a path to strengthen its balance sheet. In
July of 2002, Mpower completed a financial recapitalization that retired
approximately $600 million in long-term debt and preferred stock. As of January
3, 2003, the company's remaining $50 million in long-term debt was also retired.
Coupled with the transactions announced today, the resulting new cash, reduced
operational cost structure and new financing are expected to significantly
improve Mpower's long-term viability.

         "Over the past year we believe we have executed on our vision and have
strengthened the company from both a financial and an operational perspective,"
stated Mpower Communications Chairman and Chief Executive Officer Rolla P. Huff.
"In an industry burdened




by debt-laden telecommunications companies, Mpower stands apart from the crowd
as a company completely free of long-term debt."


"The new Mpower will have geographic focus across 12 markets in California,
Nevada and Illinois with more financial and operational strength, scale and
agility," added Huff. "While our company will now be focused exclusively on
serving and growing our base of 75,000 customers in these three states, we are
extremely pleased that these agreements will provide ongoing communications
services for Mpower customers in every market and new opportunities for many of
the valued employees who will be leaving the company."
