Guide to Back Up Power: Considerations for Energy Storage Assets

Commercial and industrial businesses bear 98% of the tens of billions of dollars in costs associated with power outages in the United States each year. Despite these costs in lost production more than 80 percent of C & I energy storage installations today are NOT used for backup power.

With the cost of adding backup power being nominal when selecting the right inverter, and a pipeline of 1.3 GW of commercial and industrial energy storage installations forecast by 2021, Dynapower examines considerations for developers and end users when selecting an energy storage inverter to provide valuable backup power for their installation and maximum value for their energy storage installation.

Achieving Operational Optimization in Microgrid Implementations

With the increasing penetration of distributed generation sources, such as solar PV, as well as energy storage technologies, microgrids—small-scale versions of centralized electric grid functionality—are gaining popularity. When properly designed, built, optimized, and operated, microgrids can achieve specific goals for their owners, including cost control, reliable energy delivery, resilience, and carbon emission reduction. This paper reviews the characteristics of microgrids and their various operational objectives, showcases the feasibility analysis required to plan a successful microgrid implementation, and highlights strategies for optimizing microgrids and the technological solutions required to achieve these objectives.

Shifting the Corporate Perspective on Energy: A Service, Not a Commodity

A new business and organizational model, “Energy-as-a-Service”, is allowing Best-in-Class companies to fundamentally change the way they procure and manage energy.  This white paper explores the factors that are driving large energy users to view energy as a service rather than a commodity to lower their enterprise energy costs and while improving their competitive advantage.

Growing from 1000VDC PV Systems to 1500VDC; Why and How?

Why did the industry move from 600 volt solar arrays to 1000 volt solar arrays? The answer is simple, to reduce system costs. The value of increased system voltages is realized in infrastructure savings, reduced installation costs, and end-to-end efficiency improvements. That is the same reason that the industry is now moving from 1000 volt systems to 1500 volt systems. Central inverters have led the way, but Sungrow has just introduced a 1500V string inverter that promises a complete industry shift.

 

Utilities in the Connected Age: Strategies for Cybersecurity

Security is more than just a regulatory-driven necessity for utilities; it has become a business imperative. Most utilities can no longer do business effectively or efficiently without internet of things (IoT) technology; and events in the Ukraine have shown that large-scale attacks against power grids can succeed. Beginning July 1, 2016, utilities must comply with NERC’s Critical Infrastructure Protection standard, v6, which features an expanded scope and emphasis on security, compared to previous NERC CIP regimes. Most U.S. utilities already enjoy a relatively high level of awareness and sophistication about cybersecurity, compared to other industries — but there are some common weak spots. To respond effectively to ever-shifting cyber threats and vulnerabilities, utilities must adopt a risk-based security approach that exceeds regulatory requirements. This paper recommends an integrated utility security program that encompasses physical and digital security technology, staffing and training, leadership support, cross-departmental collaboration and cross-sector coordination.
