Energy Storage

June 14 – Enel Group’s first utility-scale, stand-alone battery energy storage - the 25 MW/12.5 MWh Tynemouth project - is about to start operations, supported by a four-year contract with British System Operator National Grid to provide grid-balancing services. Enel bought the storage venture from Element Power in May 2017, and invested about 20 million Euros in the overall project, including construction.

UK Power Reserve has partnered with Fluence to deliver the first phase of its 120 MW battery storage portfolio to the British power grid. Fluence agreed to provide three 20 MW storage systems at sites in the Midlands and North West using its Advancion technology. All three new sites are due operational during winter 2018/19.

The Swiss arm of MAN Diesel & Turbo and ABB Switzerland have started to jointly develop, produce and commercialize a three-way Electro-Thermal Energy Storage system (ETES). Based on so-called ‘charging cycle,’ the ETES uses surplus renewable-electricity to generate heat and cold for storage in insulated reservoirs. The stored heat and cold can then be converted back into electrical energy on demand.

The world’s first liquid air energy storage (LAES) plant is being run by Highview Power at Bury, near Manchester. Supported by £8 million in UK government funding, the 5MW/15MWh LAES plant is the first operational LAES demonstration plant at grid-scale, providing backup electricity supply that is being utilized by the demand response aggregator KiWi Power.

Deployment of large-scale battery storage is rapidly increasing across the United States, but capital costs of energy storage systems vary greatly, dependent on the technology uses. Energy-oriented batteries systems, used for peakload shaving, are designed for longer durations and consequently have higher average costs per kilowatt and lower costs per kilowatthour. This type is mostly used in the California Independent System Operator (CAISO) area.

Technology of battery-based energy storage has matured and industry stakeholders in some regions of the United States have gained experience financing, procuring, and operating power storage installations. Lithium-ion chemistries batteries currently make up 80% of large-scale U.S. power storage, and most of the capacity is being installed in California followed by the Pennsylvania-New Jersey-Maryland Interconnection (PJM).

Mexico, the largest buyer of US pipeline gas and LNG, is preparing a tender for strategic storage at depleted oil and gas reservoirs. Cenagas, the Mexican National Natural Gas Control Centre, has already selected four underground sites – Acuyo, Brasil, Jaf and Saramako – from a list of 15 proposed sites. Registering strong bidding interest from foreign players, the Mexican Energy Secretariat (Sener) will hold the tender in September 2018.

Opinions differ widely when it comes to energy storage. Dominion Energy in its new long-term plan for Virginia and North Carolina notes that the price of battery storage showed it wasn’t ready for full consideration. Instead, the utility is looking to intensify the deployment of new gas-fired peaking power plants.

Dry natural gas production in the United States is forecast to reach a new record of 80.5 billion cubic feet per day (Bcf/d) in 2018, up from 73.6 Bcf/d in the previous year. According to the EIA’s latest Short-term Energy Outlook (STEO), the rise in US natural gas production will help replenish storage levels from current lows and support increasing natural gas exports, both via pipeline to Mexico and in the form of LNG.

Technological challenges are “taking root on the grid,” the New York Independent System Operator (NYISO) said with reference to an array of battery storage projects and the first offshore wind project off Long Island. Looking ahead, NYISO expects both baseload and peakload power demand to fall by about 0.14% through to 2028, caused by a rising use of distributed power sources and  energy efficiency measures.

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.

News in Brief

Mitsubishi produces methanol in Trinidad

Jan 20 – Mitsubishi Gas Chemical Company has launched commercial operations of a methanol and dimethyl ether plant in Trinidad and Tobago. The plant has an annual production capacity of one million tons of methanol and 20,000 tons of dimethyl ether, which can be used as an alternative fuel for cars and power generation.

First 8-cylinder B36:45 engine delivered

Jan 19 – Rolls-Royce has delivered the first 8-cylinder variant of its Bergen B36:45 gas engine to a tomato producer in Belgium. The medium speed genset is planned for delivery this spring and will drive an onsite power plant that generates 4700 kW electricity and 5520 kW heat. The new engine offers a 20% increase in power per cylinder and will replace an existing Bergen 12-cylinder B35:40 genset.

Moody’s upgrades Enel to Baa1

Jan 18 – Moody’s Investors Service has upgraded Enel’s long-term rating to Baa1, with a stable outlook.
