Hydraulic Fracking In the USA there has been a considerable interest in hydraulic fracking to extract gas from shale deposits. A glut in capacity has resulted in relatively cheap gas but the lack of liquification plants and political pressure prevents export of liquefied gas. Some suggest fracking could be a solution in the UK. However there is a huge difference in hydrocarbon extraction policy when the USA is compared to the UK. In the USA you own any minerals beneath your land. In the UK the Crown Estate owns all coal, oil or gas deposits regardless of who owns the land above. Clearly there is less financial motivation for a UK land
owner to extract gas if it belongs, not to him, but to the Crown Estate. As a result a fracking industry is expected to develop at a much slower rate than in the USA and will therefore be unlikely to reach significant volumes over the next decade. The UK has a relatively small amount of shale gas compared to Poland, France, Norway, Sweden and Ukraine. Imported gas will continue to play an important role in the UK electricity generation market although UK storage capacity remains shockingly small at just 4 percent of yearly consumption (15 days). Currently OFGEM, the UK energy
regulator, predicts the UK will drop to a 4.2 percent generation margin by 2015 (that is we have only 4.2 percent more generation or import capacity at peak demand). Ironically higher margins are required as green generation capacity increases as renewable do not offer 100
percent guaranteed availability. A 15 percent margin is considered the safe minimum limit, anything less could result in power restrictions on days of peak demand or in the event of unexpected maintenance shutdowns (for example problems on one of the import gas pipelines). “Demand-side action” will increasingly be used as margins decrease. “Demand-side action” is the friendly term used for shutting down large electricity users at times of peak demand, for which they will be generously rewarded. If overall load still exceeds generation capacity the voltage across the grid can be reduced to prevent the supply to smaller consumers being completely cut.
