Date Enacted:06/25/2007 Effective Date:01/01/2008
Summary:
Note: In October 2008 the Missouri Public Service Commission issued a final rulemaking order
implementing the provisions of SB 54. Among the notable clarifications
offered under this rulemaking order are determinations that (1) monthly
net excess generation will be credited to the customer at the utility's
cogeneration rate and (2) systems larger than 10 kW must carry at least
$1 million in liability insurance and smaller systems must carry
$100,000 in liability insurance. The rulemaking order appeared in the
January 2, 2009 edition of the Missouri Register and is scheduled to
become effective February 28, 2009.
Missouri
enacted legislation in June 2007 (SB 54) requiring all electric
utilities -- investor-owned utilities, municipal utilities and electric
cooperatives -- to offer net metering to customers with systems up to
100 kilowatts (kW) in capacity that generate electricity using wind
energy, solar-thermal energy, hydroelectric energy, photovoltaics (PV),
fuel cells using hydrogen produced by one of the aforementioned
resources, and other sources of energy certified as renewable by the
Missouri Department of Natural Resources. Systems must be intended
primarily to offset part or all of a customer's own electricity
requirements, and must be located on a premises owned, operated, leased
or otherwise controlled by the customer. The new law took effect
January 1, 2008.*
Net metering is available until the total rated generating
capacity of net-metered systems equals 5% of a utility's single-hour
peak load during the previous year. However, in a given calendar year,
the aggregate capacity of all approved applications for interconnection
is limited to 1% of a utility's single-hour peak load for the previous
calendar year. If a customer's existing metering equipment is not
capable of measuring the net amount of electricity produced or
consumed, or if it is necessary for the utility to install "additional
distribution equipment to accommodate the customer-generator's
facility," then the customer must pay for these costs.
Customer net excess generation (NEG) during a given month
is credited to the customer's next bill at a rate at least equivalent
the utility's avoided-cost rate. Any NEG remaining at the end of a
12-month period is granted to the utility with no compensation for the
customer.
Utilities must offer a net-metering tariff or contract that
is identical in electrical energy rates, rate structure, and monthly
charges to the contract or tariff that the customer would be assigned
if the customer were not an eligible customer-generator. Utilities may
not charge the customer any additional standby, capacity,
interconnection, or other fee or charge that would not otherwise be
charged if the customer were not an eligible customer-generator.
Any costs incurred by a utility under Missouri's
net-metering statute are recoverable in the utility's rate structure.
The estimated generating capacity of all net-metered systems counts
towards the respective utility's accomplishment of any renewable-energy
portfolio target or mandate adopted by Missouri. Each utility must file
an annual report describing the status of its program.
Utilities not regulated by the commission are required to
adopt initial rules by October 1, 2008, including regulations ensuring
that simple contracts will be used for interconnection and net
metering. For systems up to 10 kW, the application process includes
all-in-one document that includes a simple interconnection request,
simple procedures, and a brief set of terms and conditions.
*Prior to the June 2007 legislation, Missouri
required certain utilities to offer “dual metering” to consumers. “Dual
metering” is much less favorable to consumers than net metering.
