Synthetic AAEs decouple the physical flow of electricity from the financial flow. This will further increase the flexibility of contractual agreements. With respect to synthetic chaining contracts (also known as sPPAs), producers and consumers agree on a price per kilowatt-hour of electricity, as does a physical AAE. However, electricity is not delivered directly to the consumer from the power generation facility. Instead, the producer`s energy service provider (for example. B an electricity distributor) takes the electricity generated in its clearing group and acts (in the short-term electricity markets, to cite an example). The consumer`s energy supplier (for example. B, a municipal plant) obtains exactly the power profile that the manufacturer makes available to its energy service provider on behalf of the PPA consumer partner, the purchase being made on a platform such as the spot market. In the synthetic AAE, this flow of electricity is now supplemented by what is called a differential contract. In this contract, the AAEs parties aim to compensate for the difference between the agreed price of AAEs and the actual spot market price. This means that each counterparty in the AEA has two cash flows: one with the energy service provider concerned and the other with the AAE contractor. In any event, the payments add up to the price of the AAEs set at the beginning and offer both parties the desired price guarantee. Without direct physical delivery between the contracting parties (such as an AAE on site) and without a direct link between them (such as an off-site AAE), this is a simple and administratively economical AAE.
It is well suited to cases where a producer does not create or does not wish to create its own balance sheet group, to cite an example. At the end of the PPP agreement, some suppliers will transfer ownership of the solar installation to the building owner. This can be a good deal, because panels usually come with 25-year guarantees, so that at the end of a 10-year contract, you have an additional 15 years to take advantage of “free” solar power. They have to replace inverters that have shorter warranties, but this is often not a bad deal. In accordance with a physical AAE, the purchaser of the company will receive a long-term AAE (usually lasting more than 10 to 15 years) with a renewable energy generator in order to take some or all of the energy generated by its facility (or asset portfolio) with a fixed price per MWh. Under an AAE, the buyer is usually a utility company or a company that buys electricity to meet the needs of its customers. With the production distributed with a commercial variant of PPA, the buyer can be the occupant of the building – for example. B a business, a school or a government. Electricity distributors can also enter into AAEs with the seller. AAEs can cover 100% of project costs and the price of electricity purchased by the supplier is generally lower than the retail price of electricity.
This makes AAE cash flow often positive for the customer from day one.
