Pipeline giant Enbridge Inc. has added to its long-term spending plan as it pours money into a slew of growth projects.

The company updated its long-term funding plan Thursday, and now expects it capital program between 2012 and 2016 to reach $35-billion, nearly $11-billion of which is expected to come from the company's cash flow. Most of the remainder will be debt.

"Since the long-term funding plan discussed at our investor conference last fall, we have achieved greater-than-expected progress in the development of attractive new growth opportunities, including those already announced and those yet to be" Richard Bird, Enbridge's chief financial officer, said in a statement.

"An update to our funding plan now indicates an incremental equity requirement over the 2012-2016 period."

Enbridge issued $500-million in equity via a bought deal Thursday, selling 10.85 million shares at $46.11 each.

The Calgary-based firm has billions of dollars worth of projects under construction right now.
