It is great to see a DNO being so proactive in both accepting levels of energy storage onto the grid they manage, and to be consulting with industry on future deployment.  They, like most if not all DNO's are certainly not short of interest or formal applications. I've always found WPD to be forward thinking, attending industry shows and making an effort to connect with the renewable industry for many years. Even way back when some shows were still in halls no bigger than a basketball court!
