Load Profiles: How different storage systems, microgrid controllers fit specific C&I sites
Posted on Thursday September 10, 2020

Several case studies of storage installations supporting a variety of C&I solar+storage sites. Includes information on load profiles, goals of projects, and the specific solution each site chose. An example of a profile is below: Site: Church Load profile: This church in Bakersfield, Calif., is actually multiple facilities. It has two sanctuaries, a gymnasium, offices and classrooms. While certain small areas are occupied intermittently during the week, the primary activities are one Sunday service and an evening service each week. During these services, load is far higher than the rest of the week. Plus, the evening service starts just before sunset — so solar offsets almost none of the peak demand for the week. The facility had an electricity bill of around $40,000 per year — half on an energy charge, half on demand. The 100-kW solar system was sufficient to address the customer's entire annual energy usage but did essentially nothing to address demand. Goal: Boost the value (and reduce the payback time) of a solar array with Extensible Energy's DemandEx load flexibility software by reducing demand charges and shifting energy out of expensive time of use (TOU) periods. Solution: Software • 100-kW PV array• 16 controllable HVAC package ...

Batteries begin storing wind and solar energy for the Texas grid
Posted on Monday September 07, 2020

Conventional wisdom maintains that wind and solar power depend on affordable energy storage, and until battery prices drop, the United States will rely on natural gas and coal-fired power plants. A few years ago, most analysts thought it would take decades, but the clean energy future is much closer than most people think.

As Residential Solar Deployments Fell, the US Home Battery Market Powered On
Posted on Thursday September 03, 2020

Even the COVID-19 pandemic could not stop the residential storage market from growing in the second quarter, according to the new Energy Storage Monitor. Even as the coronavirus pandemic sent the U.S. economy into free fall this spring, the energy storage industry delivered its second-best quarter ever in terms of megawatts installed. Despite social-distancing orders, more customers than ever before added batteries in their homes to store solar power and provide backup power amid hurricanes, wildfires and other types of grid outages. Residential storage companies installed 48.7 megawatts/112 megawatt-hours in Q2, up 10 percent from the previous quarter, according to the new Energy Storage Monitor report released Thursday by Wood Mackenzie and the U.S. Energy Storage Association. That marks the fifth consecutive quarterly deployment record for residential storage, something that larger battery segments have never achieved.

Duke Energy contracts Wärtsilä for three battery storage facilities

Andrew Cuomo's clean energy target of 3,000 megawatts – the equivalent of 40 per cent of the homes in the state – of energy storage by 2030.

1.5GWh of 'Made in America' zinc batteries joining Texas, California grids from Eos Energy Storage
Posted on Tuesday September 01, 2020

Agreements to deploy 1GWh of novel aqueous zinc battery energy storage in Texas and 500MWh in California have been struck by technology provider Eos Energy Storage, marking a massive scale-up in expected installations for the systems. Eos Energy Storage said in a press release yesterday that its long duration zinc hybrid cathode batteries, which are best suited for 4-6 hour discharge but have the flexibility to go to higher power and longer run-times through de-rating power, have been ordered by 'technology agnostic' power producer International Electric Power for 1GWh of projects to be connected to the grid run by the Electricity Reliability Council of Texas (ERCOT).

Long-duration energy storage makes progress but regulation lags technology
Posted on Thursday August 27, 2020

The U.S. energy storage market was booming until the Covid-19 virus hit — and it continues to boom, despite, or because of the pandemic. The U.S. energy storage market is forecast to grow from 523 MW in 2019 to 7.3 GW in 2025, according to energy analyst Wood Mackenzie. Today's energy storage market is absolutely dominated by lithium-ion batteries, but a host of new energy storage technologies are being brought to market — offering longer durations and potential improvements in project economics and functionality.

How ahead-of-schedule energy storage adoption could help Nevada avoid blackouts, electric supply issues - The Nevada Independent
Posted on Monday August 31, 2020

Combined under-construction and pending storage projects will see NV Energy surpass a 1,000 megawatt energy storage goal seven years ahead of schedule. Still, as the state continues to move toward a greater reliance on renewable energy — including a gradual ramp up to a 50 percent Renewable Portfolio Standard by 2030 — renewable energy advocates say the state needs to take proactive steps now to avoid future resource adequacy issues -- i.e. blackouts or brownouts.

Largest US battery resource connects to CAISO grid, signaling next phase in California's storage growth
Posted on Tuesday July 14, 2020

Jason Burwen, vice president of policy at the Energy Storage Association, said in a statement that the announcement reflects the relentless movement of energy storage into mainstream electric system operations. "It's also important to note that this project is a standalone battery storage system. While there can be benefits to integrating storage directly with generation as a 'hybrid resource,' the LS Power storage system in CAISO is a reminder that effective grid operations can utilize the flexibility of storage as a standalone asset," Burwen said.

Global power grids decentralise towards a flexible future
Posted on Wednesday July 15, 2020

Redesigning national power grids is central to the strategy of moving toward cleaner, greener energy supplies. Perhaps most crucial are the attempts of "decentralisation", which involve energy being generated closer to where the demand is, as opposed to coming from larger power stations. Building this greater flexibility into networks is creating investment opportunities and a new role for utilities, energy aggregators, storage suppliers, as well as engineers.

New group led by IREC aims to simplify energy storage interconnection
Posted on Wednesday July 15, 2020

Holding on to power - Why storage is a crucial part of the state's new energy vision
Posted on Monday July 13, 2020

Today, only 5 percent of New Jersey's total electricity generation is from renewable sources. This is mostly solar with some biomass and wind. However, the 2019 NJ Energy Master Plan sets a goal of 100 percent of the state's energy needs coming from clean energy by 2050. There are many pieces to hitting this target, but the state has mandated that 50 percent of its electricity should come from renewable sources by 2030. For example, 3,500 megawatts (MW) of offshore wind generation capacity is a part of this mandate. This figure represents 20 percent of today's 18,000 MW of total electric generator capacity.
