Networks
SSE has an ownership interest in five economically-regulated energy network companies:
- Scottish Hydro Electric Transmission (100%);
- Scottish Hydro Electric Power Distribution (100%);
- Southern Electric Power Distribution (100%);
- Scotland Gas Networks (50%); and
- Southern Gas Networks (50%).
Our electricity networks transmit and distribute electricity to around 3.5 million businesses, offices and homes via almost 130,000km of overhead lines and underground cables. Our gas networks distribute gas to around 5.7 million homes, offices and businesses via 75,000km of gas mains.
We estimate the total Regulatory Asset Value (RAV) of our economically-regulated 'natural monopoly' businesses is now £5.5bn, comprising:
- £590m for electricity transmission;
- £2.70bn for electricity distribution; and
- £2.2bn for gas distribution (ie 50% of the businesses' total RAV of £4.4bn).
SSE is the only energy company in the UK to be involved in electricity transmission, electricity distribution and gas distribution. Together, these lower-risk economically-regulated natural monopoly businesses, featuring RPI inflation-linked revenue, provide a financial backbone and operational focus for SSE and balance our activities in the competitive Generation and Supply markets.
