One sheet per plant. None of them is a permit.

AURION POWER, STAR KEY Energy PLC. These are floor plans for a credit discussion: what building each project needs, and which project does not belong on the 150 ha pin. They are not a survey, not an IFC set, and not a drawing an Ethiopian-registered architect has stamped.

Site

The lease rectangle is the sponsor’s 150 ha, unsurveyed. CSP sits outside it on purpose.

Photovoltaic building

Phase 1 power is a 50 MWac field. This sheet is one MV and inverter building. How many copies, and where the rows sit, waits on the hectares that are actually buildable.

Geothermal power house

Binary ORC. The air-cooled condenser is a yard, not a room. Nothing here is ordered before the well test.

One well pad

A single pad. The program is three to six wells. A field plan would be fiction before the first well is completed.

Control, admin, workshop

The occupied building. Control is separated from the workshop so a weld does not sit on the SCADA wall.

CSP — a different project

Shown so a reader can see the power block, and so it cannot be papered onto the Tendaho lease.
