Rapid, affordable energy transformation possible ...· Using high-voltage direct-current transmission grid (HVDC) to supplement the current electrical grid may make this possible. HVDC lines, which are in use around the world, reduce energy losses during long-distance transmission. The following is a study using the HVDC model to push the theoretical envelope and see what is possible.

Transformers and Switchgear: Where is it All Going?"The typical lead time for switchgear at the moment is six months and for transformers 18 to 36 months (before the market pressures the lead time for transformers was nine months). At the current time there is a vicious circle – the greater the orders received the greater the backlog and the harder it is becoming to deliver on time ...
