Energy Storage

Elon Musk, the man at the helm of Tesla, has hinted at the company’s Q1 investors’ call that a giant 1 GWh energy storage project would be announced soon. Highlighting the impact of Tesla’s 129 MWh battery in South Australia, he said “its grid stabilization was much greater actually than even a gas turbine plant, which normally respond quite fast.”

Siemens is applying its electrification experience in the marine industry to offshore oil and gas, focussing on reducing emissions and risk in harsh operational environments. BlueVault, Siemens’ advanced lithium-ion battery-based solution, is suited for both all-electric and hybrid energy-storage applications.

ITM Power and Northern Gas Networks (NGN) have announced the outcome of a feasibility study, evaluating the potential of deployment and cost-effective operation of 50MW energy storage capacity within the boundaries of the NGN gas distribution network. Low Thornley in Gateshead is being recommended as the most suitable site for a power-to-gas demonstration plant in the size range 50-100MW.

April 17 – Enel X, the energy services division of Enel Group through its US subsidiary EnerNOC, has struck an agreement with Algoma Orchards of Ontario, Canada to deploy a 1 MWh lithium-ion battery storage system under a contract spanning 11 years. The storage system will be deployed in the first half of 2018.

GE Reservoir, a new power storage platform for AC or DC coupled systems, condenses 4MWh of energy capacity into a 20’ box. The system improves battery the lifecycle by about 15%, delivers 5% higher efficiency and reduces installation time and costs, GE said, adding it already has a 20 MW, 80 MWh pre-launch commitment.

About two-thirds of the utility-scale battery storage capacity installed in the United States is located in two electricity markets: the California Independent System Operator (CAISO) and the PJM Interconnection which covers all or parts of 13 eastern states.

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.
