Vayu Tracker - for Large Energy Users

Electricity makes up a large percentage of your monthly energy spend. Imagine being able to pay wholesale prices for it. With Vayu’s electricity tracker product, you can do just that.


Vayu Shield

Vayu Shield is a totally flexible product that offers price certainty by allowing you to fix all or a portion of your electricity for whatever usage period that suits you.

Innovative Renewable Energy Solutions

Vayu can offer a variety of solutions to help large energy users operate in a more sustainable fashion. The benefits include:

  • Controlling electricity costs into the long-term
  • Access to renewable or green power
  • Reducing your carbon footprint, thus achieving sustainability CSR objectives


At Vayu we constantly look at innovative ways of working with our Customers on these priorities and delivering integrated renewable energy solutions through:

Corporate PPAs

A corporate PPA brings consumers and generators together irrespective of location, generating capacity or supply requirements with no capital outlay required by the Customer. In addition to offering the benefit of cost predictability, Vayu can connect a specific generation source like a wind farm with a specific demand source of a Customer. Whilst also managing the volumes and pricing elements, it is also attractive from a Corporate Social Responsibility (CSR) perspective, as it can directly support local communities and lower the Company’s carbon emissions.

On-site generation

Some Industrial and Commercial Customers have their own onsite generation. Onsite generation, or auto-production, is where an energy consumer installs a generation facility at the same physical location as their demand. The electricity generated is used to power its own premises first and any excess power is spilled to the grid creating an income stream.

Vayu provides an attractive solution via a monthly invoice to facilitate both the supply of electricity required from the grid and also payment for the times the generator exports excess power to the grid.

The availability of a flexible contract was a key deciding factor for College Proteins when considering switching our electricity provider. Since signing up to Vayu’s Electricity Tracker, we have benefitted from lower wholesale market prices and the savings have been considerable. Participation at the Electricity Auctions allowed us a further opportunity to secure power at competitive rates, which assists us in reducing our energy bills.

Vayu’s energy supply partnership with Dalata goes beyond the supply of natural gas. For example, Vayu is installing smart metering across all our ROI hotel sites, which will enable us to view, manage and control all our hotel site’s energy consumption and costs like never before. Stephen Clarke
I am not surprised that other large customers are also seeing value in using Vayu as their gas supplier. Vayu seems to be doing all the right things to establish the company as a leader in this market.
