Five Takeaways: Early Moves and Current Trends in Energy Storage

McDermott continues its dialogue with renewable industry leaders to provide the latest market updates on the disruption, challenges and opportunities COVID-19 presents to the industry. This week, we focused on the energy storage market and hosted Chris McKissack, CEO at GlidePath Power Solutions. Glidepath was an early mover in energy storage. GlidePath is now one of the largest energy storage developers and independent power producers in the US, with over 100MW of commercially operating battery projects, 445 MW of battery storage and renewable energy projects, and 2.1 GW of greenfield development pipeline of battery storage projects across the US. We had an engaging discussion spanning the benefits of being an early mover in the storage space, the current state of the dynamic energy storage market, and successful strategies you can use to approach the opportunities and challenges stemming from COVID-19.

1. Batteries Can Now Serve as “Shock Absorbers” for the Grid

Batteries are capable of doing much more than just “energy shifting,” where a developer simply stores energy from a solar project from one time of day and dispatches it onto the grid at another time of day. For instance, we are now able to place stand-alone batteries closer to load than most large-scale wind and solar projects. This provides an opportunity for frequency response and regulation in that it allows grid operators to dispatch generators more efficiently. This is important to today’s market. 60 years ago, we had an unpredictable load, but very predictable generation. You could ramp-up and ramp-down generation by turning a dial. Today, we have more and more intermittent resources and renewables dispatching the grid resulting in more demand response. We now have both unpredictable load and unpredictable generation, making it much more difficult for the operators of the grid to balance the two. There is an opportunity for batteries act like shock absorbers for the grid and keep things stable.

2. Batteries Remain Key to Energy Shifting and Financial Energy Arbitrage

Despite the versatility of batteries, energy shifting remains an important use for batteries, particularly for financial energy arbitrage. Batteries provide an opportunity for load customers to marry their purchase of energy with their load and shape it to a particular financial profile. We see a lot of this usage by datacenters today and this trend will continue.

3. Early Movers in Energy Storage Will Likely Emerge from COVID-19 Even Stronger

The battery energy storage market was poised for a period of sustained growth in 2020 and 2021, but it is unlikely to emerge totally unscathed from COVID-19. According to some forecasts, market growth is now forecast to decline for 2020. The pace of the recovery will depend how quickly the COVID-19 crisis is resolved. However, depending on the agility of the company’s management and the status of the development of its projects going into COVID-19, some battery storage companies may come out of COVID-19 even [...]

Maryland Likely to Become First State to Adopt Energy Storage Tax Credit

UPDATE: This bill was signed into Maryland law on May 4, 2017 with a $75,000 maximum credit for commercial systems. A previous version of the bill offered credits to commercial systems up to $150,000.

In April, the Maryland legislature passed a bill creating a state income tax credit for the costs associate with installing an energy storage system. Governor Larry Hogan is expected to sign it into law. Unlike measures in other states such as California and Massachusetts, the Maryland bill does not contain mandated amounts of energy storage that utilities must procure. Instead, if the current bill is signed, Maryland will be the first state in the country to incentivize the deployment of energy storage systems by offering a tax credit. Presently, an energy storage system can qualify for the federal investment tax credit if it is installed alongside a solar photovoltaic system. This is the first ever tax credit for storage-only projects, although qualified energy storage systems still may be paired with renewable energy projects.

Under the terms of the bill, a taxpayer will receive a credit equal to 30 percent of the installed costs of the system, not to exceed $5,000 for a residential system or $150,000 for a commercial system. The incentive program has a funding cap of $750,000 per year, and applications for the credit will be approved on a first-come, first-served basis. Additionally, the tax credit may not be carried over for use in future tax years. The tax credit is currently slated to run from 2018 to 2022. (more…)
