Understand the connection before committing to the plant.
A grid-injection proposal needs an identified network interface, acceptable gas and a commercial connection pathway. Establish requirements with the relevant operator early. Access regulation and a physical connection assessment serve different purposes; neither guarantees a particular cost or available capacity.

Give the operator a useful project brief
Provide site coordinates, product composition, minimum and maximum flow, operating profile, intended start and project stage. Distinguish measured data from design assumptions. Identify existing utility constraints and the proposed connection corridor.
Define the acceptance specification
Agree quality, pressure, measurement, odorisation where relevant, monitoring and shutdown arrangements. Applicable standards and operator requirements must be checked for the particular interface. A methane-percentage figure alone is not a complete acceptance specification.
Establish cost and responsibility boundaries
Ask which party designs, owns and maintains each asset. Identify connection, compression, metering, reinforcement and commissioning requirements. Request assumptions behind indicative costs and the information needed to refine them. No generic national fee should replace this process.
Assess low-demand conditions
Check whether the distribution system can receive proposed production across seasons. If output exceeds local demand, consider curtailment, alternative delivery or reverse-flow investment. Include these outcomes in the revenue model rather than assuming all production will be accepted.
Align connection and customer agreements
Technical access should support the intended sale arrangement. Confirm delivery point, measurement basis, interruptions and certificate ownership. Equipment procurement should follow a sufficiently defined interface so late specification changes do not undermine the design.
Keep the project record current
Record dated milestones for enquiry, feasibility, design, approvals, agreement, construction and commissioning. Clearly distinguish a connection enquiry from an executed agreement. Use operator correspondence as project evidence, with permission before publishing commercially sensitive details.
Frequently asked questions
Does an access arrangement approve my injection equipment?
No. Economic regulation, engineering acceptance and project approvals are separate requirements.
What data should I provide first?
Location, proposed gas composition, flow range, operating profile, project stage and expected timing.
Can I rely on a national connection timeframe?
No universal timeframe is established here; obtain the operator’s project-specific process and dependencies.
