NextEra Energy and Hawaiian Electric Industries filed 92 more pages of responses Wednesday with the Hawaii Public Utilities Commission to requests for information about their proposed $4.3 billion merger.

The latest filing follows more than 1,000 pages of information submitted to the PUC by NextEra last month. Those documents contained 54 binding commitments from NextEra regarding a range of dimensions of the deal and how the company would serve Hawaii customers in the aftermath of its acquisition of HECO, raising to 85 the total number of commitments the company has made thus far.

Included in the new filings are details on how NextEra arrived at its projected average costs savings estimates for Hawaii ratepayers for next five years, if the deal is approved by the PUC.

Hawaiian Electric also supplied five years worth of charitable giving data, revealing giving that has fluctuated from a high of $2,345,000 last year to $2,148,000 in 2010. NextEra has promised to continue that record of charitable giving in the amount of at least $2.2 million a year for the next decade, if the sale goes through.

The companies didn’t provide everything that was asked for, saying that several information requests were inappropriate. Included in the 92 pages are five pages of “general objections” detailing reasons why they find 22 types of requests problematic.

Despite the growing amount of explanatory detail NextEra is making public, leading Hawaii officials, including Gov. David Ige and Consumer Advocate Jeffrey Ono are on record as strongly opposing the deal, as are multiple community organizations. The PUC has said it may not make a decision on whether to allow the acquisition until June of next year, giving the company as much as nine months to modify the deal and convince Hawaii leaders and ratepayers that it is in the state’s best interests.

Here are the 92 pages of responses:
