		(4)  no person owns, controls, or owns and controls in 
any combination more than 40 percent of the installed generation 
capacity located in an ERCOT zone as provided by Subsection (a-2) 
and as determined according to Section 39.154(a)(2).

	(a-2)  For purposes of Subsection (a)(4), the ERCOT zones are 
the congestion zones determined by the ERCOT independent 
organization and in effect as of January 1, 2007.  This zonal 
restriction expires on the later of the first anniversary of the 
date of the implementation of the ERCOT nodal market or December 31, 
2009.  In determining the percentage of installed generation 
capacity owned or controlled by a person under Subsection (a)(4), 
the commission shall, for purposes of calculating the numerator and 
notwithstanding any other provision of this chapter, exclude 
capacity:
		(1)  from a generating facility that uses nuclear 
energy to generate electricity for sale and that is constructed 
after January 1, 2007;
		(2)  from a coal-fired generating facility that uses 
integrated gasification combined cycle technology or undiluted 
high-flame temperature oxygen combustion technology that excludes 
air; or
		(3)  from a generating facility that uses a renewable 
energy technology, as that term is defined by Section 39.904(d),

proportion of that capacity that is equal to the proportion the 
municipality's or electric cooperative's ownership bears to the 
total ownership;
		(5)  in an amount equivalent to the sum of firm 
bilateral energy or capacity sales for delivery in the relevant 
ERCOT zone that are not indexed to real time energy clearing prices

adding up to, 12 months or longer by the power generation company or 
through its marketing affiliate to unaffiliated third parties as 
reduced by firm bilateral energy or capacity purchases for delivery 
in the same ERCOT zone that are not indexed to real time energy 
clearing prices for a term of, or consecutive or overlapping terms 
adding up to, 12 months or longer, provided that the power 
generation company and marketing affiliate shall certify to the

from receiving the market clearing price for services offered in 
any market operated by the independent organization,".
	(6)  Add the following appropriately numbered item to read as

	(__)  In Section 39.156, Utilities Code, as amended by

following:
	(b-1)  An electric utility or power generation company that 
owns, controls, or owns and controls in any combination more than 40 
percent of the total installed generation capacity located in an 
ERCOT zone, as defined by Section 39.154(a)(2), not later than the 
90th day after the date the utility or company knew or should have 
known that its generation capacity exceeds the 40 percent 
limitation prescribed by this subsection, shall file a market power 
mitigation plan described by Subsection (b)(2).  Subsections (f), 
(f-1), (f-2), (f-3), and (f-4) apply to the filing.  The commission 
may not require divestiture or auction of installed generation 
capacity described by this subsection or take any action under this 
section that prohibits an electric utility or power generation 
company from constructing additional generating facilities.  For 
purposes of this subsection, the ERCOT zones are the congestion 
zones determined by the ERCOT independent organization and in 
effect as of January 1, 2007.  This zonal restriction expires on the 
later of the first anniversary of the date of the implementation of 
the ERCOT nodal market or December 31, 2009.  In determining the 
percentage of total installed generation capacity owned or 
controlled by a power generation company under this subsection, the 
commission shall, for purposes of calculating the numerator and 
notwithstanding any other provision of this chapter, exclude 
capacity:
		(1)  from a generating facility that uses nuclear 
energy to generate electricity for sale and that is constructed 
after January 1, 2007;
		(2)  from a coal-fired generating facility that uses 
integrated gasification combined cycle technology;
		(3)  from a generating facility that uses a renewable 
energy technology, as that term is defined by Section 39.904(d), 
and that is not dispatchable;
		(4)  from a generating facility owned by a municipally 
owned utility or electric cooperative, provided that if the 
facility is owned only partly by the municipally owned utility or 
electric cooperative, the commission shall exclude only the 
proportion of that capacity that is equal to the proportion the 
municipality's or electric cooperative's ownership bears to the 
total ownership;
		(5)  in an amount equivalent to the sum of firm 
bilateral energy or capacity sales for delivery in the relevant 
ERCOT zone that are not indexed to real time energy clearing prices 
and that are for a term of, or consecutive or overlapping terms 
adding up to, 12 months or longer by the power generation company or 
through its marketing affiliate to unaffiliated third parties as 
reduced by firm bilateral energy or capacity purchases for delivery 
in the same ERCOT zone that are not indexed to real time energy 
clearing prices for a term of, or consecutive or overlapping terms 
adding up to, 12 months or longer, provided that the power 
generation company and marketing affiliate shall certify to the 
commission each month the amounts excluded under this subdivision;  
and
		(6)  from generating facilities that were mothballed as 
of January 1, 2007, and remain mothballed.
