However, the energy storage sector will continue its strong showing from 2016, with commissioned capacity set to exceed 1GW for the first time, Liebreich and McCrone say. “We predict a doubling of new capacity from this year’s 700MW to 1.5GW, almost all of it lithium-ion batteries. We are going to see a further reduction in battery prices of at least 15% this year, after a 70% reduction in the past five years.”

TDU Delivery Charge: TDU stands for transmission and delivery utility — in other words, the utility company in your area that is actually piping the energy from the power generation companies into your home. (Remember, REPs in Texas are just the middleman.) The TDU delivery charge is set by the utility and is consistent from plan to plan and provider to provider within its service areas. For example, AEP , the TDU for Corpus Christi, charges the same delivery fee for all TXU, Direct Energy, and Reliant plans. You don't typically get a choice in utility company, and therefore, these fees are pretty much unavoidable, non-negotiable, and won't factor into choosing an electricity plan or provider.
When you decide to switch, and have got the ball rolling with your new supplier, you should settle any outstanding debts. If you have bills that are more than 28 days old, you might find that you can’t change supplier until you’ve paid them. But there are some exceptions to the 28 days – for example, if you are less than £200 in debt, then your switch could still go ahead as normal
