How California demand response has opened up to energy storage, virtual power plants

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.

EFR: Inside Vattenfall’s first grid-balancing UK project

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.

Navigant on energy storage as ‘non-wires’ alternative for utilities and grid operators

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.

How Tesla and Vivint are taking different paths to the ‘one stop shop’ destination

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 the past month we have heard a lot about the future of storage in the UK. From plans by the government and regulator to enable greater flexibility across electricity networks to changes to technical rules governing the market, there's been a sense that a great deal is changing. Analyst Lauren Cook of Solar Media's in-house market research team takes a look at the utility-scale pipeline figures behind the headlines.

In the UK, a new, quarter of a billion-pound innovation competition for batteries has been launched, while plans for overhaul of the energy sector promising a “determined, joined-up, far-sighted and deliberate approach from government” appear to have been met with relish by the industry. Consultant Robert Ede goes beyond headlines to look at what this might really mean in practical terms.

Interest in energy storage in the Middle East is ‘ramping up significantly’, as we reported last week in an extract from this interview with IHS Markit analyst Julian Jansen. His firm is forecasting 1.8GW of energy storage for the region by 2025 – from an installed base of next-to-nothing today. Jansen talked us through some of the drivers, market dynamics and the general picture of what we might see developing.

On the back of rapidly decreasing costs for energy storage and solar photovoltaics (PV), consumers wishing to achieve a low-cost and reliable supply of power are considering grid defection—or at least, partial grid-defection—as an increasingly attractive alternative. Julian Jansen, analyst at IHS looks at the economics of grid defection in Europe today and in the future - and how its proliferation could impact the energy industry as a whole.
