Grid connection contributions

Every new wind farm, solar plant, factory or housing estate needs a grid connection, and someone has to pay for the cables, transformers and substation upgrades. The money usually goes to the network operator, which owns the assets afterwards. Both sides need to decide what they have bought or sold. This guide covers the network operator's revenue, assets contributed in kind, and the payer's accounting, with an example from each side.

Short answer

Grid connection contributions are payments, or assets, that customers give a network operator to connect them to the grid. For the network operator, the contribution is consideration under IFRS 15, which replaced IFRIC 18: if connecting the customer is a distinct service, revenue is recognised when the connection is made; if it is not distinct from the ongoing network service, it is deferred as a contract liability and recognised over the period of that service. Assets transferred by customers are non-cash consideration at fair value. For the generator or developer that pays, the connection is property, plant and equipment if it controls the assets, otherwise usually an intangible right of access amortised over the project's life. In this guide's example, a US$ 12 million connection payment is amortised at 0.48 million a year by the wind farm that pays it.

What are grid connection contributions?

Payments that a customer, such as a generator, developer or large user, makes to a transmission or distribution network operator to build or upgrade the connection it needs. Sometimes the customer builds the assets itself and hands them over to the operator. Rules on who pays what vary by country: some regimes charge the full cost of the connection, others only the assets used solely by the customer, with wider reinforcement recovered through tariffs.

How does the network operator account for contributions?

The customer is obtaining services from the operator's ordinary activities, so IFRS 15 applies. The key question is what the contribution pays for. If the connection is a distinct service, for example because the customer can take its supply or sell its output through another party once connected, revenue is recognised when the connection is complete. If the customer must buy ongoing network services from the same operator, and the connection has no value without them, the connection is not distinct and the contribution is part of the price of those services: it is a contract liability, recognised as revenue over the period the services are expected to be provided. The assets built are the operator's property, plant and equipment under IAS 16, depreciated over their lives. See performance obligations.

Grid connection contributions: both sides of one connection

A wind farm developer pays a network operator US$ 12 million to connect a new 25-year project. The operator builds a substation and cables costing 10 million, which it owns. The connection is only usable with the operator's ongoing network service, expected to be provided for 40 years.

Each side spreads the payment over the period it benefits from it: the operator over the service period, the developer over the life of its project. If the developer's project ends sooner than expected, any remaining intangible asset is written off.

What if the customer builds and transfers the assets?

When a developer builds the connection assets and transfers them to the operator, the operator receives non-cash consideration. It recognises the assets as property, plant and equipment at fair value and the same amount as consideration, recognised as revenue on the same basis as a cash contribution, either on connection or over the service period. The developer derecognises the assets it built and recognises an intangible right of access if it still benefits.

How does the payer decide what it has bought?

If the payer owns and controls the connection assets, such as its own substation and export cable up to the point of connection, they are its property, plant and equipment. If the network operator owns them, the payer has paid for a right of access to the grid, which usually meets the definition of an intangible asset because it is identifiable, controlled through the connection agreement and brings future economic benefits. It is amortised over the shorter of the connection right and the project's useful life. A payment that only secures a place in the connection queue may be a prepayment until the connection is made, and is written off if the project is abandoned. See IAS 38 intangibles.

How does US GAAP compare?

US utilities generally record contributions in aid of construction as a reduction of the related plant cost under regulatory accounting, rather than as revenue, which differs from IFRS 15. Payers apply similar reasoning about whether they control the assets. See power and utilities accounting and regulatory deferral accounts.

Questions people ask

How does a network operator account for connection contributions under IFRS 15?

As revenue on connection if the connection is distinct; otherwise as a contract liability recognised over the period of the ongoing network service.

What replaced IFRIC 18 Transfers of Assets from Customers?

IFRS 15, which treats assets transferred by customers as non-cash consideration measured at fair value.

How does a generator account for a grid connection payment?

As property, plant and equipment if it controls the assets, otherwise usually as an intangible right of access amortised over the project's life.

Is a payment to join a connection queue an asset?

Usually a prepayment until the connection is made, written off if the project is abandoned.
