Energy Storage

Greensmith Energy, a part of Wärtsilä group, has completed two grid-scale energy storage systems in Texas. Called ‘Texas Waves’, the two 9.9-MW short-duration storage facilities are fed by E.ON’s 249-MW Pyron and the 197-MW Inadale wind farms, both near Roscoe, delivering energy on short notice to the Electric Reliability Council of Texas (ERCOT).

Arenko Group, a leading energy storage systems operator, has selected GE to deliver a 41-MW battery – one of the largest in the UK – to supply power on demand to approximately 100,000 homes. The grid-scale energy storage is designed to enhance efficiency of power transmission, balance renewable energy supply and help reduce customers’ energy bills. To be sited at a strategic location in the Midlands, the battery storage will commence operations in 2018.

Jan 17 – California Public Utilities Commission (CPUC) has ruled that Calpine needs to replace three gas-fired peaking power plants with energy storage facilities by 2019, “if feasible and at a reasonable cost to ratepayers.” Calpine had initially sought regulatory permission to maintain “must-run status” for the two 47-MW peaking plants in Feather River and Yuba and a 605-MW gas power plant in Metcalf.

Fluence, the new joint venture by Siemens and AES Energy Storage, has started operations at the start of this year, backed by a dedicated financing programme from Siemens Financial Services, and a substantial contract to supply a 400MWh battery system in California.

Jan 11 – Kilkenny County Council is processing an application Greener Ideas, a joint venture set up in 2009 between Bord Gáis Energy and Mountside Properties,for the construction of a 100MW battery energy storage system. Initially the project partners intended to develop an open-cycle gas turbines power plant on the site which is now listed for the battery project.

Commenting on the UK Government’s decision to de-rate battery storage ahead of the Capacity Market auction in February next year, UK Power Reserve (UKPR) said it “accepts and understands” this move while remaining confident about the future of battery storage in Britain. UKPR also underlined its goal to bring 120MW of battery storage online before 2020.

Controversy is mounting in Australia over whether the lifetime of AGL Energy’s 2,051-MW Liddell power plant should be extended – as proposed by the Turnbull government – even though the operator wants to shut down the “costly and unreliable” unit in 2022. A new report finds the government’s stipulated lifetime extension would cost around $3.6 billion over five years, compared to $2.2 billion for a combination of wind power, demand side-response and energy efficiency measures.

ITM Power has secured funding from the Department for Business, Energy and Industrial Strategy (BEIS) to deploy large scale Power-to-Gas energy storage on the Northern Gas Networks’ (NGN) distribution grid. In a subsequent study, both partners will examine the potential and cost-effectiveness of such storage solutions, starting from the 50 MWh range.

GEMS software from Greensmith Energy, a Wärtsilä company, will be utilized to help realise 2.4 MW/2.4MWh energy storage system test bed that CW Group is realising on behalf of Singapore's Energy Market Authority (EMA) and SP Group, a leading energy utility in Asia Pacific. The facility is due to be fully operational during the latter part of 2018.

Seeking to complement fossil power plants, South Australia has invited bids from investors in energy storage and bioenergy to share a $150 million fund. The tender is part of the government's wider $550 million energy plan that will see the world’s largest battery being built, and additional flexible gas power capacity. Applications for the $150 million fund close on September 28.

Aug 14 – GE Renewable Energy has booked a turnkey contract with Star Pumped Storage Ltd for the 344 MW Kokhav Hayarden hydro pumped storage station, the second to be installed in Israel. GE Renewable Energy is responsible for the design, manufacture, supply and installation of all electro-mechanical and hydro-mechanical equipment as well as complete balance of plant for the two 172 MW pumped-storage units. The project will be executed by a consortium led by Chinese EPC SinoHydro.

June 29 – Following this week’s working meeting in Belgrade between Gazprom CEO Alexei Miller and Dusan Bajatovic, director general of Srbijagas, the Gazprom head has signed a roadmap with Serbia’s Minister of Mining and Energy, Aleksandar Antic on how to jointly expand the Serbian gas transmission system. The expansion of the Banatski Dvor underground gas storage facility in Northern Serbia was also discussed. A memorandum, signed early June 2017, stipulates that the UGS facility's capacities will be increased from 450 to 750 million cubic meters. Serbia is a transit country for Russian pipeline gas exports which first reach Turkey and then get transported onwards to Austria and Western Europe.

Though Centrica CEO Ian Conn told the BBC this morning that closure of its 3.4 Bcm Rough gas storage facility will not destabilize Britain’s gas supply – given the possibility to import LNG and source gas from Norway and the EU through several interconnectors – some analysts see it differently. Commenting on Centrica’s move, Wood Mackenzie analyst Graham Freedman said the decision not reopen Rough storage comes as “no surprise” and makes “good commercial sense” for Centrica. However, he believes the implications on the UK's future security of gas supply “will no doubt lead to a UK Government review of its position, particularly in light of current Brexit negotiations.”

June 9 – Car manufacturer Renault-Nissan is finalising plans to build a 100-MW power storage plant in Europe, based on disused and recycled car batteries. Similar to rival Tesla’s electricity storage arm, the latest move of Renault-Nissan indicates the company’s aspiration to cultivate a second-hand battery market. The projected power storage facility, if built, would have enough capacity to meet the electricity needs of 120,000 homes. The carmaker confirmed the news, stating “We're working with The Mobility House on several programs including a major energy storage project that is currently still in the study phase.”

Utility-scale capacity provided by various energy storage technologies and renewables beyond wind, solar and hydro, collectively accounted for 4% of the electricity generating capacity in the United States in 2016. Latest EIA figures shows a small, but growing trend towards demand-side response – vital tools for balancing electricity markets the United States, and elsewhere.
