High Energy Users

In addition to private wire solutions, ILOS can support sleeved PPA structures where renewable electricity generated by an ILOS project is sold to energy buyers via a licensed energy supplier.  The supplier “sleeves” the power through a customer’s existing grid connection, integrating it into your normal electricity supply contract.

This approach allows organisations to maximise the value of locally generated renewable electricity through on-site use and export, while maintaining existing supplier terms or negotiation new ones.

Typically, for partners looking to work with ILOS on sleeved PPAs, electricity is first supplied directly to the end user site via a direct connection to the substation on site within the same grid network, with surplus solar generation or battery discharge exported to the grid.  The customer’s electricity supplier manages balancing, settlement and supply arrangements to make up the balance between energy generated and consumed onsite, and that imported from the grid to make up any shortfall.

This structure enables ILOS customers to benefit from both dedicated on-site renewable infrastructure and grid-based renewable supply, while ensuring the solar project operates efficiently throughout the year.

By combining a direct supply with sleeved export arrangements, ILOS projects can be sized to optimise both site demand and overall generation performance.

Sleeved PPAs are increasingly used where organisations want to insulate their operations against rising energy costs with a dedicated connection into the substation at site, while retaining the flexibility of grid supplied electricity.

They are particularly relevant where:

• Existing electricity supplier relationships need to be maintained
• Energy demand spans multiple locations
• Flexibility is required alongside long-term pricing
• Energy users scaling faster than grid connections allow

In short, Sleeved PPAs provide a route to renewable procurement that works with operational demands.

ILOS approaches sleeved PPAs as part of a broader energy strategy, not just a standalone contract, negotiating with the customer’s supplier to manage excess or stored generation from a dedicated connection.

Typical delivery includes:

• Analysis of your load profile and procurement structure
• Identification of suitable generation assets and volumes
• Structuring of the PPA through a licenced energy supplier
• Integration with battery storage and export strategies
• Ongoing optimisation as demand and generation evolve
