About excess distributed generation (EDG)
In accordance with Ind. Code sec ch. 8-1-40, on April 7, 2021, the IURC approved Cause No. 45378, which sets the rate customers will receive for excess distributed generation. The rate is recalculated each year based on the average wholesale rate from the previous year multiplied by 125%. The new rate is effective March 1st of each year. The current rate is available on the SIGECO Electric Tariff under Rider EDG.
To qualify, residential, small business, and industrial customers may install a system to generate their own electricity, up to 1 megawatt, to supplement the supply they get from CenterPoint Energy. Under Rider EDG, CenterPoint’s electric meters measure the amount of electricity supplied by the company to the customer to power the customer’s home or business (inflow in the Electric Tariff). CenterPoint charges the customer for this electricity at the customer’s applicable retail rate defined in the SIGECO Electric Tariff. Simultaneously, CenterPoint’s electric meters measure the amount of electricity generated by the customer’s generating system and not used by the customer (outflow in the Electric Tariff). CenterPoint credits the customer for this electricity at the rate defined in Rider EDG in the SIGECO Electric Tariff.
Common customer generation systems include:
Wind
Most wind technologies can be used as stand-alone applications, connected to a utility power grid or combined with a photovoltaic system.
Solar
Solar power is commonly produced when photovoltaic (PV) systems convert sunlight into electricity. Roof panels are a popular choice.
Other options
Some other customer generation options include biomass, hydropower and hybrid systems.
About net metering
The net metering tariff is for residential, small business and industrial customers that installed an eligible generation system, prior to implementation of Rider EDG.
Under this tariff, when a net metering customer's renewable generator is producing more power than is being consumed, the customer essentially generates credits toward the bill. When a net metering customer uses more power than is being produced, the meter records the usage in the standard fashion. Net metering customers are charged only for the "net" power they consume from CenterPoint Energy which has accumulated over a designated period or, if their renewable energy-generating systems make more electricity than is consumed, they may be credited for the excess electricity contributed to the grid over that same period.
Customers will remain eligible for the net metering tariff under the following conditions:
-
Systems installed by Dec. 31, 2017
Customers with systems installed by Dec. 31, 2017 will be credited at the full retail price* for excess power put back on the grid until July 1, 2047. After 2047, excess power will be credited at the Rider EDG.
-
Systems installed after January 1, 2018 but before implementation of Rider EDG; or Customers with an approved, and signed, Net Metering Interconnection Agreement before implementation of Rider EDG
Customers with systems installed after January 1, 2018 but before implementation of Rider EDG will be credited at the full retail price* for excess power put back on the grid until July 1, 2032. After 2032, excess power will be credited at the Rider EDG.
Customers with an approved, and signed, Net Metering Interconnection Agreement before implementation of Rider EDG will be eligible for credit at the full retail price* for excess power put back on the grid until July 1, 2032 provided the following conditions are met.
Approved, and Signed, Interconnection Agreements before Implementation of Rider EDG: Customers that submit applications for Net Metering, and receive an approved, signed Interconnection Agreement before Implementation of Rider EDG on May 14, 2021 must complete system installation within one year of the approved, signed Interconnection Agreement to remain eligible for credit at the full retail price* for excess power put back on the grid until 2032. After 2032, excess power will be credited at the Rider EDG.
- Qualifying Biomass Systems installed between now and July 1, 2022
Customers with systems installed after implementation of Rider EDG but before July 1, 2022 will be credited at the full retail price for excess power put back on the grid until 2032. After 2032, excess power will be credited at the Rider EDG.
Grandfathering Provisions:
Customers will also remain eligible for the net metering tariff under the following conditions:
- In accordance with GAO 2017-2 and Ind. Code 8-1-40-13 and 8-1-40-14, any current Rider Net Metering customer that replaces (as defined in GAO 2017-2) their existing net metering facility after the Company's transition date will need to apply for approval of the new facility as a Rider EDG customer and will be deemed no longer eligible for Rider Net Metering. However, repairs, updates, and upgrades to portions of the net metering facility that do not increase the nameplate capacity (i.e. the alternating current output of the inverter(s)) of the net metering facility will not be considered to be replacing the net metering facility.
- Or if a new customer establishes service at a premise that was previously eligible for Rider Net Metering. If needed, please contact the New Service Department by email to newservice@centerpointenergy.com to request an interconnection agreement.
How to get connected
There are a few key steps you must complete to begin the interconnection process, including a formal application, signing an Interconnection Agreement, a site drawing and an inspection. Use the project checklist and guidelines before beginning your customer generation project.
