On the Role of Regulatory Policy on the Business Case for Energy

This paper presents a SWOT analysis of the impact of recent EU regulatory changes on the business case for energy storage (ES) using the UK as a case study. ES technologies (such as batteries) are key enablers for increasing the share of renewable energy generation and hence decarbonising the electricity system. As such, recent

Using overhead covered conductors at high voltages

While covered conductors for medium voltages are usually made of aluminium alloy and covered with a 2 mm layer of black weather resistant XLPE, this single layer is not sufficient at higher voltages, so triple extruded XLPE layers are used. Work on developing overhead covered conductors goes back to the late 1970s, with 20 kV lines.

How Does a Solar Farm Connect to the Grid?

If the nearest transmission line to your property has a voltage of, say, 115 kV (115,000 volts), the output voltage from the solar farm needs to "step up" to 115 kV to feed power into it. Likewise, the power that line carries to a neighborhood 50 miles away eventually needs to "step down" in voltage so that homes can use it.
