Introduction
Contracts are one of the building blocks of a portfolio on Tensor Cloud. They feed into asset simulations and into asset management baselines.
PPAs and bilateral agreements set the terms on which an asset's generation and environmental value are sold during the contract period. Each asset can be linked to one PPA, one bilateral agreement, or one of each. An aggregation contract is a service contract between you, as the aggregator, and the owner of the assets. Aggregation contracts are available when enabled for your workspace; contact Tensor to enable them.
To see the contracts in your workspace, select Contracts in the main navigation bar. Click a contract in the list to open its overview, described in PPA view, Bilateral agreement view, and Aggregation contract view.
Contract types
Tensor Cloud supports three types of contracts.
Power purchase agreements (PPAs)
A PPA sets the terms on which an asset's generation is sold to the PPA offtaker during the contract period. To create one, press Add new at the top right of the contract list, select PPA in the Select contract type dialog, and press Continue. A page opens where you enter the PPA terms; PPA settings describes each section.
Bilateral agreements
A bilateral agreement models the direct sale of an asset's environmental value in the form of non-fossil certificates (NFCs). You can manage it independently of any PPA. To create one, press Add new at the top right of the contract list, select Bilateral agreement in the Select contract type dialog, and press Continue. A page opens where you enter the agreement terms; Bilateral agreement settings describes each section.
Aggregation contracts
An aggregation contract records the service you provide to an asset owner and the fees the owner pays for it. PV contracts charge a service fee: a monthly base fee plus a fee per kWh. Grid battery contracts take a share of the net trading result. Each asset under the contract has its own supply dates and, for grid batteries, its own initial fee. An asset can be under several aggregation contracts at once.
Signed and Started aggregation contracts count toward realized revenue. Changing one does not re-run any simulation.
To create one, press Add new at the top right of the contract list, select Aggregation contract in the Select contract type dialog, and press Continue. A page opens where you enter the contract terms; Aggregation contract settings describes each section.
In the contract list, an aggregation contract shows its signing date under Start date, its initial term under Term, and the asset owner under Counterparty.
Changing a PPA or bilateral agreement re-runs the simulations of all connected assets. Depending on the size of your portfolio, this can take a few minutes.
