Distribution grids, mini-grids and interconnectors and Transformers and power electronics

Energy flows from distribution grids, mini-grids and interconnectors to transformers and power electronics; energy flows from transformers and power electronics to distribution grids, mini-grids and interconnectors; their prices have moved together.

Distribution grids, mini-grids and interconnectors (energy) and Transformers and power electronics (energy): 3 relationships.

How they are linked

1. Energy flow

Physical flow · Direct · Distribution grids, mini-grids and interconnectors → Transformers and power electronics

Chargers and adaptors convert mains power for devices.

2. Energy flow

Physical flow · 85% of flow · Transformers and power electronics → Distribution grids, mini-grids and interconnectors

Distribution transformers deliver usable voltage.

• 85% of Transformers and power electronics's energy goes this way

3. Price link: grid equipment

Cost and price · Strong · Both ways

Inverters, transformers and smart switching devices are installed together in distribution upgrades. The indices share the grid spending cycle, so yearly moves correlate at 0.70, though monthly changes barely relate, at 0.10, because list prices are revised infrequently.

• 0.10 monthly change correlation
• 0.70 12-month change correlation
• 0.84 fitted elasticity
