This letter is intended to raise stakeholder awareness of a very important project that the electricity distribution network licensees have recently initiated. This is the review of Engineering Recommendation (ER) P2.  

ER P2 has acted as the foundation stone for the planning of distribution networks for many decades. It is essentially unchanged from ER P2/5 which was introduced in 1978. It therefore pre-dates the development of smart grids, wide spread distributed generation and active customers.

The network companies have decided that there is a sufficiently strong case to carry out a thorough review of ER P2. We fully support this initiative and are represented on the industry working group that the network companies have established to lead this work. The first public engagement event took place on 1 May 2015.
