APS Issues RFPs for More Renewable Energy

Arizona Public Service Company (APS) announced it is issuing two requests for proposals next month as part of its campaign to bring more solar and wind energy into its portfolio. The two new RFPs will add enough solar and wind resources to power more than half a million homes, about 2,500 megawatts, by 2021, company officials said. Earlier this year, the company also successfully closed two RFPs for large battery installations to store renewable energy to use after the sun goes down.

NEC to Install More than 20MW of Municipal Energy Storage Projects in New England

NEC Energy Solutions has announced six additional energy storage projects of more than 20 MW at municipal power plants throughout New England. The new projects follow the model of the Sterling Municipal Light Department installed two years ago that has saved ratepayers more than $1 million on their utility bills. These energy storage systems reduce costs for transmission and capacity charges, which directly benefit the ratepayers. In Sterling, NEC’s GSS® Grid Storage Solution also provides resiliency for the community in the event of an outage from severe weather and other causes

Long Read: The Dawn of Megastorage

Plummeting costs, industry maturity, and the ever-increasing penetration of global renewables are expanding the use cases for battery storage technology. Over the past year and a half, storage projects are increasing significantly in both scope and capacity.

Department of Energy Announces $40 Million in Funding for 29 Projects to Advance H2@Scale

The U.S. Department of Energy (DOE) has announced approximately $40 million in FY 2019 funding for 29 projects to advance the H2@Scale concept. The focus of H2@Scale is to enable affordable and reliable large-scale hydrogen generation, transport, storage, and utilization in the United States across multiple sectors. Funded through the DOE’s Office of Energy Efficiency and Renewable Energy (EERE), with contribution from DOE’s Office of Nuclear Energy, the selected projects will advance hydrogen storage and infrastructure technologies and identify innovative concepts for hydrogen production and utilization including grid resiliency.

Buckland Sets a Milestone for Rural Energy Capabilities with New Li-ion Battery

A few years ago, the village of Buckland in northwest Alaska set a milestone a leader in rural renewable energy when it got two turbines and three solar panels installed. Now, the village has hit an even more ambitious target: unofficially becoming the first village to power itself entirely off of renewable energy stored in recently installed lithium-ion batteries.

Battery Storage Called Into Action As UK Suffers Country-Wide Power Cuts

Battery storage assets were called into action last week after the UK suffered country-wide power outages following a transmission system stress event. On August 9th, two large generators were disconnected from the UK’s power system almost simultaneously, effectively taking 2GW worth of electricity generation within minutes of each other. That collapse in generation sent the country’s transmission grid frequency to dip, so National Grid, the country’s electricity system operator, called on reserve and flexible generation capacity to respond, with many operators dispatching battery storage capacity to meet National Grid ESO’s calls.

Energy Storage Earns More Awards for KIUC

Kauai Island Utility Cooperative led the nation again in 2018 for interconnection of energy storage watts per customer, and ranked second in annual energy storage capacity, according to the Smart Electric Power Alliance. In 2018, KIUC posted more than 3,000 Wh/C, nearly six times more than the next ranked utility: Sterling Municipal Light Department in Massachusetts. This is the second year running that KIUC topped the list of storage watts per customer.

Energy Storage is Critical to Microgrid Development: Microgrid 2019

Microgrids increasingly depend on solar-plus-storage — or the ability to generate solar power on site and to store excess electrons in batteries that would release that energy when it is needed. Energy storage provides a Swiss army knife of services, from shaving peak load to storing and injecting wind and solar electrons onto the grid. It enhances reliability while also increasing efficiencies and allowing for more green energy on the grid.

Batteries Instead of New Power Plant on Long Island?

When the Long Island Power Authority said last summer that it was going to need new power capacity in the next few years, most people assumed that meant new generating stations or new transmission cables. But of the 16 companies that submitted proposals, one, AES Energy Storage, took an entirely different tack: it proposed batteries.

Microgrids promote energy independence

The Sacramento Municipal Utility District demo a “microgrid” that many other utilities have resisted. Microgrids promote energy independence, even allowing customers to secede from the larger utility grid powered up by their own resources. In an energy sector dominated by monopolies and centralized planning, microgrids could be a game-changer.
