We’re here to help! We know that the topic of sustainable energy storage is somewhat complicated. Here are two of the most frequently asked questions we hear from prospective customers.

(Click on question to expand answer)
1. What advantages do I gain from energy storage?
Federal and State Incentives. Through 2019, battery storage when paired with renewable energy installations is eligible for the federal 30 percent Investment Tax Credit, which encourages companies to develop long-term investments that drive competition and technological innovation, and in turn, lower costs for consumers. In 2020 the ITC is reduced to 26 percent, and then it goes down to 22 percent the following year. In 2022 it drops to zero for residential structures, while the credit for commercial and utility drops to 10 percent and stays at that rate permanently.

Financial Savings. San Diego Gas & Electric, the IOU that serves San Diego County, has a history of raising its regular rates, and will continue to do so for the foreseeable future. Meanwhile, SDG&E buys energy from solar customers when they produce an excess. The utility also sells it back to them during periods when their arrays are not producing. However, a proposal pending approval from the CPUC to change the length of the buying and selling periods, known as Time of Use (TOU), basically amounts to a rate increase. Installing an iDES3 battery system would take you out of the rate-hike equation.

Leaving the Grid Behind. In the aim of meeting the state’s sustainable energy standard that calls for 100 percent renewable power by 2045, SDG&E is building new infrastructure. Yet such development will not be paid for out of company profits, it will be paid for out of rate-payers’ pockets. SDG&E, a Sempra utility reported fourth-quarter 2016 earnings of $151 million, up from $144 million in the same quarter of 2015.

Solar-Plus-Battery Storage Increases Property Values. There’s an immediate financial reward for adding rooftop or ground mount solar arrays and battery storage. But they also increase the value of your home or commercial building should you decide to sell, according to real estate agents and appraisers.

2. What makes iDemand Energy Storage systems the best choice?
