Draft US law calls for energy storage tax breaks

Fri, 04/12/2019 - 13:10 -- Hugh Finzel
US Congressman Mike Doyle

Draft legislation has been introduced to the US House of Representative that would see energy storage receive the same investment tax credit as solar installations.

The ‘Energy Storage Tax Incentive and Deployment Act’, introduced by Pennsylvania representative Mike Doyle (pictured), would incentivise both utility-scale energy storage projects and small battery systems for residential use.

The current tax code allows an investment tax credit for energy storage when it is installed in conjunction with a solar energy system; this bill would extend the investment tax credit for energy storage investments in a wider range of applications and provide greater assurance to prospective investors.

Exide invests in VRLA storage plus solar at Portugal plant

Fri, 04/12/2019 - 10:14 -- Hugh Finzel

US battery manufacturer Exide Technologies is investing in a solar power facility coupled with VRLA battery storage at its production plant in Castanheira do Ribatejo in Portugal.

Another solar facility will be installed at Exide’s recycling plant in Azambuja, Portugal.

The solar-plus-storage system will pair 500kWh worth of Sonnenschein A600 VRLA from GNB— a division of Exide Technologies— with solar. The two sites will have a combined total of around 10,000 solar photovoltaic panels, with a total generating capacity of 3.8MWp. The company said this was equivalent to the power requirements of more than 2,000 homes.

Hawaiian approval for six solar-plus-storage systems

Fri, 04/05/2019 - 10:05 -- Hugh Finzel

The Hawaiian Public Utilities Commission has approved contracts for six solar-plus-storage projects, totalling 274MW/998MWh, as the price of power generated from such projects falls below traditional generation methods.

The approval comes as the cost of solar projects fully backed by four-hour batteries has fallen below the regulators’ threshold of US$0.10 per kWh, which the Commission said is “cheaper than both gas peaker plants and Hawaiian Electric Industries’ current cost of fossil fuel generation, much of which is petroleum based”.

This announcement comes less than 18 months after AES Distributed Energy started work on a 20MW/100MWh storage system on Kauai island, at which point the cost of power for solar-plus-storage stood at $0.11 per kWh.

Florida plans ‘world’s largest’ battery

Fri, 04/05/2019 - 09:45 -- Hugh Finzel

Florida Power & Light Company (FPL) is planning to build “the world’s largest solar-powered battery” to replace a pair of 1970’s-era natural gas power generators in the state.

The 409MW/900MWh Manatee Energy Storage Centre (MESC), which will receive power from FPL’s existing solar power plant in Manatee County, is expected to start operation in late 2021.

FPL is also planning a series of smaller battery installations, solar power plants, and efficiency upgrades to existing combustion turbines across the state, in order to replace 1,638MW of generating capacity.

Sodium-sulfur batteries pilot for UAE solar park

Tue, 03/12/2019 - 12:44 -- Hugh Finzel

Japan-based battery developer NGK Insulators has supplied sodium-sulfur (NaS) batteries for a pilot energy storage project in the United Arab Emirates.

The 1.2MW/7.2MWh batteries were supplied to Dubai’s Electricity and Water Authority (DEWA) for the project at the Mohammed Bin Rashid Al Maktoum Solar Park (MBRAMSP). Ingeteam provided power and control electronics for the battery storage facility.

The NaS system will be used for “energy time shifting, frequency control and voltage control”, as well as to increase grid stability and reduce CO2 emissions. It will be “the first energy storage system paired with a solar PV plant at a grid-scale level in the United Arab Emirates”, the companies said.

ENGIE solar-storage park for South Africa

Mon, 02/18/2019 - 00:00 -- Hugh Finzel

ENGIE has started commercial operations of its 100MW Kathu Solar Park (KSP) to “provide clean and reliable energy to 179,000 homes” in South Africa.

KSP is a greenfield concentrated solar power project with “parabolic trough technology” and equipped with “a molten salt storage system that allows for 4.5 hours of thermal energy storage”.

The project has been realised under round 3.5 of South Africa’s Renewable Energy Independent Power Producer Procurement (REIPPP) programme, a competitive tender process launched “to facilitate private sector investment in renewable energy generation”.

Redflow storage sures up electric supply for Thai village

Mon, 02/18/2019 - 00:00 -- Hugh Finzel
Ban Pha Dan

Australia-based Redflow has provided a hybrid battery system coupled with solar energy generation to create a microgrid that will provide a reliable power supply in a remote village in Thailand.

The energy storage system is made up of 10 Redflow ZBM2 zinc-bromine flow batteries— which provide 10kWh apiece— and three lithium batteries. The ZBM2 batteries will provide power to the Ban Pha Dan community school, town hall, and temple, while the lithium batteries will supply energy for individual homes.

Ban Pha Dan is in Lamphun province and is surrounded by a wildlife reserve where power pylons are not permitted, meaning that the village has lacked access to electricity in the past.

BESS order boost for storage in Massachusetts

Mon, 02/11/2019 - 00:00 -- Hugh Finzel

Canada’s Storage Power Solutions (SPS) has been selected to boost the expanding portfolio of battery energy storage systems in the US state Massachusetts.

SPS has been contracted by Industria Engineering to provide a 3.5MW/8.2MWh BESS for part of a solar-plus-storage project in the town of Grafton.

The new project— which follows a 1.5MW system SPS deployed for Industria Engineering in 2018— will be used to store excess energy from a 4MW front-of-the-meter solar farm, thereby increasing solar harvesting and shifting solar generation to peak loads on the substation.

Electrolyte tanks installed for the 3MW 12MWh VRB-ESS at the Hubei Zaoyang project

Chinese vanadium redox battery manufacturer VRB Energy has begun commissioning a 3MW/12MWH vanadium redox battery, phase one of its Hubei Zaoyang 10MW/40MWh project, which will be the “largest vanadium flow battery installed in China”.

The system is being installed to integrate a large solar photovoltaic system into the grid at Zaoyang.

VRB’s chief technical officer Dr Mianyan Huang said: “We are delighted to have successfully integrated the first module of a 1MW/4MWh VRB-ESS into the grid, allowing our customer, Hubei Pingfan, to immediately benefit from cost-savings on peak-hour electricity tariffs through energy arbitrage at its industrial park.”

Georgia in mind for solar-plus-storage

Mon, 01/21/2019 - 00:00 -- Hugh Finzel
Eguana residential battery system

Creative Solar USA and Canada’s Eguana Technologies have installed and commissioned a fleet of more than 20 residential energy storage systems (ESS) in the US state of Georgia.

The initiative is part of the state’s ‘Solarize Atlanta and Carrollton-Carroll (SACC) campaigns.’

In 2018, Creative contracted more than 170 solar PV installations under the SACC campaign, for a total capacity >1.2MW. As part of the initial roll out, “two dozen of Eguana’s ‘Evolve’ ESS units were selected by Georgia homeowners as their battery system of choice.
