Revenue from Contract with Customer [Abstract]

Revenue, Remaining Performance Obligation, Expected Timing of Satisfaction

Below is a listing of all performance obligations that arise from contracts with customers, along with details on the satisfaction of each performance obligation, the significant payment terms, and the nature of the goods and services being transferred:

Revenue Recognized Over Time:
Reportable Segment	Performance Obligation	Description
SJG Utility Operations ETG Utility Operations ELK Utility Operations Wholesale Energy Operations	Natural Gas	SJG, ETG and, prior to its sale in July 2020 (see Note 1), ELK, sell natural gas to residential, commercial and industrial customers, and price is based on regulated tariff rates which are established by the BPU or the MPSC, as applicable. There is an implied contract with a customer for the purchase, delivery, and sale of gas, and the customer is billed monthly, with payment due within 30 days. Payments are received from certain customers based on a predetermined budget billing schedule. Budget billing does not represent a contract asset or liability but rather just a receivable/liability because there are no further performance obligations required to be satisfied before the Utilities have the right to collect/refund the customer’s consideration. Consideration is due when control of the energy is transferred to the customer and is satisfied with the passage of time. Budget billing liability balances are recorded within the Customer Deposits and Credit Balances line item in the consolidated balance sheets. SJG has direct connections to and long-term gas transmission services on interstate pipeline systems. The sale of gas to third parties from these pipelines prior to entering our service territory is considered OSS. These contracts to sell off-system are at a price, quantity and time period agreed to by both parties determined on a contract by contract basis. SJRG sells natural gas to commercial customers at either a fixed quantity or at variable quantities based on a customer's needs. Payment is due on the 25th of each month for the previous month's deliveries. Revenue is currently being recognized over time based upon volumes delivered (i.e., unit of output) or through the passage of time ratably as the customer uses natural gas, which represents satisfaction of the performance obligation.
SJG Utility Operations Wholesale Energy Operations	Pipeline Transportation Capacity	SJG and SJRG sell pipeline transportation capacity on a wholesale basis to various customers on the interstate pipeline system and transport natural gas purchased directly from producers or suppliers to their customers (for SJG, this is known as Capacity Release). These contracts to sell this capacity are at a price, quantity and time period agreed to by both parties determined on a contract by contract basis. Payment is due on the 25th of each month for the previous month's deliveries. Revenue is currently being recognized over time based upon volumes delivered (i.e., unit of output) or through the passage of time ratably coinciding with the delivery of gas and the customer obtaining control, which represents satisfaction of the performance obligation.
Wholesale Energy Operations	Fuel Management Services	SJRG currently has several fuel supply management contracts where SJRG has acquired pipeline transportation capacity that allows SJRG to match end users, many of which are merchant generators, with producers looking to find a long-term solution for their supply. Natural gas is sold to the merchant generator daily based on its needs, with payment made either weekly or biweekly depending on the contract. Revenue is currently being recognized over time based upon volumes delivered (i.e., unit of output) coinciding with the delivery of gas and the customer obtaining control, which represents satisfaction of the performance obligation.
Retail Services	Electricity	SJE sells electricity to commercial, industrial and residential customers at fixed prices throughout the life of the contract, with the customer billed monthly and payment due within 30 days. Revenue is currently being recognized over time based upon volumes delivered (i.e., unit of output) or through the passage of time ratably coinciding with the delivery of electricity and the customer obtaining control, which represents satisfaction of the performance obligation.
Renewables	Solar	Solar projects earn revenue based on electricity generated. The customer is billed monthly as electricity is being generated, with payment due within 30 days. The performance obligation is satisfied as kilowatt hours of energy are generated (i.e., unit of output), which is when revenue is recognized.

Renewables	Fuel Cell	The fuel cell projects earn revenue based on electricity generated. The customer is billed monthly as electricity is being generated, with payment due within 30 days. The performance obligation is satisfied as kilowatt hours of energy are generated (i.e., unit of output), which is when revenue is recognized.
Renewables	CHP	Marina sold MTF/ACB in February 2020 (see Note 1). Prior to its sale, Marina had a contract with a casino and resort in Atlantic City, NJ to provide cooling, heating and emergency power. There were multiple performance obligations with this contract, including electric, chilled water and hot water, and each of these was considered distinct and separately identifiable performance obligations that were all priced separately. These performance obligations were satisfied over time ratably as they were used by the customer, who was billed monthly.
Retail Services	Energy Procurement Consulting Services	AEP and EnerConnex provide energy procurement consulting services. These businesses match energy suppliers with end users and are paid commissions by energy suppliers. The commissions received on energy procurement contracts (whether received at the beginning of a contract or paid under monthly terms) are earned and recognized over the duration of the underlying contracts as energy usage occurs, which represents satisfaction of the performance obligation. The resulting contract liabilities are not material as of December 31, 2021, 2020 and 2019.

Revenue Recognized at a Point in Time:
Reportable Segment	Performance Obligation	Description
Renewables	SRECs	The customer is billed based on a contracted amount of SRECs to be sold, with the price based on the market price of the SRECs at the time of generation. This does not represent variable consideration as the price is known and established at the time of generation and delivery to the customer. The performance obligation is satisfied at the point in time the SREC is delivered to the customer, which is when revenue is recognized. Payment terms are approximately 10 days subsequent to delivery.

(a) A receivable is SJI's and SJG's right to consideration that is unconditional, as only the passage of time is required before payment is expected from the customer.

(b) All unbilled revenue for SJI and SJG arises from contracts with customers. Unbilled revenue relates to SJI's and SJG's right to receive payment for commodity delivered but not yet billed. This represents contract assets that arise from contracts with customers, which is defined in ASC 606 as the right to payment in exchange for goods already transferred to a customer, excluding any amounts presented as a receivable. The unbilled revenue is transferred to accounts receivable when billing occurs and the rights to collection become unconditional.
