We often hear about California’s leading position in solar and latterly in energy storage. Perhaps lesser known than direct policy support for energy storage and renewable technologies is the way California’s network operator (CAISO) is starting to reconfigure how it procures demand response, with a positive impact for energy storage – and particularly behind-the-meter assets, as Ted Ko, policy director of Stem, explains.

The UK’s large-scale battery storage installations have reached 100MW of capacity, made up of around 50 individual sites larger than 250kW. Lauren Cook of Solar Media’s Market Research team discusses how this point has been arrived at and what we might expect to see coming next.

Having been subject to discussion for years within the academic sphere, energy storage projects have become a topic of high interest to energy sector focused investors in recent years. Philipp Lobnig of E-nable+, an online platform connecting energy projects with investors, offers his views on the key questions these investors should be asking.

Chris Pritchett of UK law firm Foot Anstey recently served as moderator for the “Developers and financiers debate” at the Energy Storage Conference at the Solar & Storage Live 2017 show in England. Afterwards, Andy Colthorpe caught up with Chris for an in-depth interview on camera.

No one moment took energy storage into the mainstream of the UK power system more than the outcome of National Grid’s August 2016 tender for Enhanced Frequency Response (EFR). Reporter David Pratt examines the business case behind Vattenfall’s first EFR project and asks what grid operators and regulators’ next moves are likely to be.

One of the ‘value of energy storage’ questions that was being asked a lot two or three years ago was around the use of batteries and decentralised system architecture instead of traditional “poles and wires” grid networks. However, advancements in this area have been slow to materialise and Navigant Research’s recent ‘Energy Storage for Transmission and Distribution Deferral’ report sought to fill the knowledge gap. Andy Colthorpe took the opportunity to ask lead author Alex Eller three quick questions around the topic.

What does it mean to be all things to all people? Does it overstretch resources to breaking point, or does it give you a chance to cast a wider net and capture market share? Vivint Solar recently joined Tesla in a race to offer whole packages including solar, storage, EV charging and other components to US customers. We talked to GTM Research’s Brett Simon on some of the dynamics of those parallel strategies.

In a world where energy storage will play an increasingly important role – in balancing renewables, reinforcing the network, and reducing energy costs – how important will ‘brand’ be?

Managing director of UK energy storage manufacturer Powerflow, Ian Murray, addresses some FAQs on what consumers should be asking about batteries before buying them for their houses.

Solar entrepreneur and financier Jigar Shah probably requires little introduction. The SunEdison founder and former CEO is now president at Generate Capital, a project financing venture for sustainable infrastructure investment. Shah spoke with Andy Colthorpe about Generate Capital’s latest solar-plus-storage projects for a school district in California, as well as sharing his thoughts on the economics of energy storage today.
