MISO’s Board of Directors Thursday rejected proposed guidelines on how the board chair makes committee appointments.

The guidelines, part of proposed changes to the Principles of Corporate Governance, were withdrawn after criticism from board members that they were “too prescriptive” and limited flexibility. The Corporate Governance & Strategic Planning Committee had earlier approved the changes by a 2-1 vote.

Some of the proposed changes spelled out the increase in the board’s membership to nine members from seven (in addition to the CEO), a change approved by the Federal Energy Regulatory Commission in June.

It was the guidelines proposed under the “Selection of Committee Members” that annoyed some directors. The guidelines spelled out the experience that should be required for membership on each of the board’s seven committees. One provision stated that membership on the nominating committee may be rotated annually.

“This is getting pretty prescriptive,” Director J. Michael Evans said. “I don’t think it’s ready for us to take up.”

The board referred the proposals back to the committee.

New Additions to MISO Board

Earlier in the day, MISO members elected two new directors: Thomas Rainwater, CEO of Rainwater Capital Management, and Paul Bonavia, executive chairman of UNS Energy, parent company of Tucson Electric Power and UniSource Energy Services.

One director is the first of two additions to the board between now and 2016 as it expands to nine members. The other takes the place of Shelley Longmuir, an attorney who had been on the board since 2006 but chose not to seek another term.

Baljit Dail, who has served on the board since 2009, was re-elected. All three will serve three-year terms.

The board is expanding from seven to eight directors effective January 1, 2015 and will add its ninth member in 2016.

Members also approved an increases in board members’ compensation. Annual retainers were increased by $10,000 to $70,000. The retainer for commission chairs was boosted by $2,500 to $7,500. The board chair also received a $2,500 increase to $15,000.

A day earlier, MISO’s Advisory Committee cast votes for new leadership. Vice Chairman Kevin Murray, executive director of the Industrial Energy Users-Ohio, was elected chairman for 2015. Tia Elliott, director of regulatory affairs for independent power producer NRG Energy, was elected vice chairman.
