Utility Interconnection

The grid tie is not the primary supply for a co-located burner but a backup and balancing path — the layer that carries the campus during burner outages.

The grid as backup, not base

For a behind-the-meter burner, the utility interconnection changes role. Instead of supplying the whole campus, it imports only when the burner is short — during maintenance, a trip, or a fuel-limited period — and it can export surplus when the burner is long. It becomes an independent reliability layer rather than the primary source.

This role is central to answering the availability gate. The grid's own availability is independent of the burner's failure modes — a plasma trip does not affect the utility feed — so the two together are far more reliable than either alone. During any planned burner maintenance window, the grid carries the load and the compute never notices.

Interconnection is also where real-world constraints bite. Interconnection queues and local grid capacity can limit how much import a site can rely on, which is one reason on-site generation is attractive in the first place — but it also means the backup path must be secured, not assumed. A campus that leans on grid import for burner outages needs that import to be firm when called.

The honest design treats the grid as an essential, independent member of the hybrid: sized to carry the load through the longest expected burner outage, and secured well enough to be trusted as backup.

• Grid imports during burner shortfalls, exports surplus
• Independent failure modes make the pair more reliable
• Carries the load during planned burner maintenance
• Interconnection capacity/queues must be secured, not assumed
