Puerto Rico Electric Power Authority

The outage began at 5:30 a.m., leaving about 1.3 million of Puerto Rico's 1.4 million customers in the dark, according to Luma Energy, the private company that operates the system. Crews have begun restoring electricity in some areas, but it may take 24 to 48 hours to fully resume service, officials said.

The continued delay in resolving the case raises constitutional concerns, a bondholder attorney said.

Calling it a "tragedy" for residents, without a negotiated setllement resolution could be years away, mediators said.

PREPA says it is short on money and Genera's parent company has said it may go out of business.

After losing its first appeal, the Puerto Rico Oversight Board initiated a second appeal with the First Circuit Court of Appeals.

The court affirmed its earlier decision, which means bondholders have a claim on the full $8.5 billion due.

Some analysts question how much a leftist governor would impact financial and bond issues.

Oversight Board says the non-consenting bondholders ideas are "not a proposal."

Puerto Rico's electric reliability is likely to continue to deteriorate without access to the capital markets, the investors said.

The study also projected a $1.475 trillion loss to productive infrastructure by 2050.

The plan involves building modern infrastructure and streamlining government operations and delivery of services.

Current Members Andrew Biggs and John Nixon will be reappointed for another three years.

PREPA and its creditors have 30 more days to negotiate a possible debt-cutting deal.

The bondholders have a lien on what has been received and not on what will be received, according to the Oversight Board and Unsecured Creditors.

The bond parties and the Oversight Board are now arguing over the meaning of the word "account."

The judges will take written statements to decide whether to rehear the case, although petitions for rehearing are generally rejected, one observer noted.

U.S. District Judge Swain wants the parties to reach an agreement and again threatened to dismiss the case.

Some PREPA bond parties suggest the bonds should paid in full, while the board is offering around 4% to those who haven't accepted a settlement.

The board's executive director said he is unsure how much longer the PREPA bankruptcy proceedings will take.

In a separate development, the board asked an appeals court to reconsider its PREPA decision.
