Curtailment Program
Priorities A – use in residences, hospitals, schools, churches, public
safety buildings, agriculture B – (1) small commercial/industrial customers
(2) plant protection to prevent danger to personnel and facilities
(3) for human needs at commercial and industrial sites
(4) power generation for start up, safety and flame stabilization
C – medium size commercial customers D – medium size industrial customers E – (1) industrial customers for feed stocks
(2) small public utility electric generating systems

Curtailment Program
Priorities F – power generating plants for electricity to serve customers
in A above and small commercial/industrial costumers
G – (1) medium size commercial customers
(2) small industrial not qualifying in B, C, D or E above H – power generating plants for electricity not included in F
and B (4) above I – (1) large users with no alternative fuels
(2) Feedstock as defined in E above with greater
consumption J – boiler fuel and other indirect flame applications not
qualifying under a preceding priority

Curtailment Program
Priorities K – Interruptible sales – Railroad Commission requires
interruptible sales interrupted prior to curtailment of
A through J above. L – Interstate sales – these are to be interrupted prior to
beginning curtailment of A through K above and as
required by law.
