operators.

(
F)
(
1) Contracts for electric service
must ensure data center operators bear the fair cost of utility service,
including but not limited to:

(
a)
infrastructure costs directly attributable to serving the data center;

(
b)
appropriate allocation of fixed costs and capacity costs;

(
c)
costs of maintaining reliability for existing customers; and
