Wärtsilä to Provide Full Energy Storage Solution for One of the Largest Power Hybrid Projects at an Off-Grid Mine in Mali

The technology group Wärtsilä will optimise the energy system of the Fekola Mine, located in a remote region in southwest Mali. This is needed to improve the mine’s operations, reduce fuel consumption, and lessen the carbon emissions. Wärtsilä has been contracted to design and engineer a cutting-edge 17MW/15MWh energy storage system based on the company’s GEMS energy management solution. 

Convergent Announces the Completion of 21 MWh of Energy Storage Projects at Two Shell Facilities

Convergent Energy + Power, today announced that the 21 MWh of industrial battery storage systems under construction at two Shell Canada Products facilities in Ontario are now operational. Convergent is the largest operator of energy storage solutions in Ontario with over 40 MW in service. The energy storage projects are a joint venture between Convergent and Shell New Energies, designed to reduce the consumption of energy for the facilities by one third of typical demand while increasing the reliability and long-term sustainability of the grid. The projects are located at Brockville Lubricants Plant and Sarnia Manufacturing Centre.

Businesses See Storing Energy While the Sun Shines as Key to California Power Shut-off Strategy

After three years of wildfires and now, blackouts, more and more business owners are looking to the power of the sun and storage of a battery pack for peace of mind. “I tell people if they have solar, think about adding batteries,” said Aron Moore, owner and president of Sun First Solar of San Rafael. “Many of our farm, winery and grocery store customers are already using solar and portable generators if needed, but today everyone is talking about storage.”

Stem Joins Forces with NEC Energy Solutions to Deliver Turnkey Offering for Solar + Storage Optimization

Stem, Inc., the global leader in artificial intelligence (AI)-driven energy storage services, announced today that it is partnering with NEC Energy Solutions, headquartered in Westborough, MA, to simplify and optimize the deployment and operation of solar + storage projects. Stem will resell and integrate its Athena AI platform with NEC’s GSS® end-to-end grid storage solution. The agreement will result in a powerful solar + storage solution for large-scale projects, leveraging NEC’s AEROS® proprietary energy storage controls and Stem’s sophisticated Athena™ AI platform to perform solar and storage optimization, wholesale market participation services, solar charging compliance and reporting, and warranty compliance and administration.

Balance-of-System Costs Falling for Non-Residential Storage

Since 2014, non-residential storage system prices have declined by more than 15 percent in the U.S. Commercial and industrial customers with predictable, peaky loads are increasingly turning to storage to help manage demand charges. Grid services are also expected to provide a key value stream by the early 2020s. Over the next five years, system costs will decline further, with all-in costs falling by more than 27 percent by 2024, according to a new Wood Mackenzie report that looks at the pricing landscape for the U.S. non-residential storage segment.

Let’s Kill ‘Utility-‘ or ‘Grid-Scale’ Storage

Ask people how they segment the energy storage industry, and you’ll often hear them divide it between customer-sited or behind-the-meter storage and “utility-“or “grid-scale storage.” But if you then ask them what they mean by “utility-scale,” you can’t get a clear answer. Is it 5 MW, 10 MW, more than 20 MW? Do they mean “front-of-meter”? Or connected to the bulk transmission system? No, we’re not calling for the end of the large-scale storage industry. We’re saying that distributed, smaller-scale storage can provide all the same value to the grid that large-scale storage can and should be explicitly encouraged to compete on playing fields that policymakers have leveled everywhere.

CalCom Energy’s $100M Fund Targets Farms for Solar-Battery Systems

In California, it’s not just vulnerable families and critical services that could use battery-backed solar systems to ride through wildfire-prevention power outages. Farms also have critical energy needs, like pumping water to crops on set schedules, or chilling them after harvest, that could face significant disruption under the state’s new wildfire prevention regime. CalCom Energy, a long-time solar and energy services provider for California’s agricultural sector, thinks it has a solution. This week, the Fresno-based developer launched a $100 million Agriculture Energy Infrastructure Fund, aimed at combining low-cost solar power-purchase agreements with the backup power of energy storage.

University Team Developing Novel Low-Cost Energy Storage System

Two Cal Poly Pomona engineering professors have won a $149,000 grant from the U.S. Bureau of Reclamation to continue development of a low-cost energy storage system using reverse osmosis concentrate (ROC), the byproduct of water desalinization plants. As droughts increase, more communities, especially in the Southwest U.S., are considering desalinization plants to meet their fresh water needs. However, ROC is harmful to the environment due to its high salt content, biocides, metals and coagulents. At the same time, the energy sector is looking for more cost-effective methods of energy storage.

Implications of Rate Design for the Customer-Economics of Behind-the-Meter Storage

This work provides insights for the two main sources of bill savings for residential and commercial customers – demand charge reductions and arbitrage of energy charges – considering a range of customer profiles and retail rate designs. Storage can reduce monthly demand charges, which are dependent on the customer’s billing demand in kW rather than the amount of energy they consume in kWh, by charging during times of low energy consumption and discharging during peak consumption hours, thereby reducing peak power consumption from the grid. Storage can also reduce electricity bills by charging the storage during low-priced hours and discharging during high-priced hours, taking advantage of price-differentials of time-varying rates. This study considers a variety of demand charge designs and rates that allow for energy arbitrage.
