Butler farms microgrid

Power from pig manure has proven to be an innovative solution to several farm challenges for a unique hog farm in rural Lillington, N.C. A report written by POWER magazine editor Aaron Larson explores how Butler Farms  installed lagoon covers for animal waste to not only reduce odors and eliminate rainwater ingress, but also to capture … [Read more...]

A Comparison of Fuel Choice for Backup Generators

natural gas backup generators

The costs of a power outage to a business can be substantial, including losses in product, revenue, productivity, and customers. With increasing severe weather events and disasters triggering greater numbers of costly power outages, there is a growing interest in generators for reliable backup power. This report discusses the costs and benefits … [Read more...]

Energy Storage: The New Efficiency

This report, which describes how states can use energy efficiency funds to provide incentives for energy storage, is a publication of Clean Energy Group (CEG), with appendices containing several white papers prepared by the Applied Economics Clinic under contract to CEG. This report explains the steps Massachusetts took to become the first state to … [Read more...]

Surviving a Catastrophic Power Outage

The nation has steadily improved its ability to respond to major disasters and the power outages that often result. But increasing threats—whether severe natural disasters, cyber-physical attacks, electromagnetic events, or some combination—present new challenges for protecting the national power grid and recovering quickly from a catastrophic … [Read more...]

California’s Changing Time-of-Use Rates: Calculating the Impact on Behind-the-Meter Solar PV and Energy Storage

solar pv

For utilities, electricity is generally more expensive and complex to deliver when demand is high. To help cover these costs, California’s utilities have traditionally imposed time-of-use (TOU) rates, which created a daily schedule that applies different prices for power based on demand trends on the grid. When demand is highest, prices are highest … [Read more...]

Innovations in Energy Generation, Storage & Networks to Improve Efficiency and Ensure Reliability

Energy Generation

At Microgrid 2018 in Chicago, experts from FuelCell Energy, Younicos and Power Engineers explored the latest innovations in energy generation, storage, microgrids and networks. Geoff Slevin, director, business development at FuelCell Energy, offered the case for fuel-cell microgrids. Fuel cells can be more efficient than competing baseload … [Read more...]

The Missing Link in Energy Storage

A number of challenges now face the electric power industry: volatile wholesale market, increasing transmission constraints, and uncertainty on the part of customers as to what this has all meant. Today, these three issues play a role in the development of hydrogen energy storage demand : Government Role Prior to deregulation in the electric … [Read more...]

Energy Storage Study

There is great potential in Massachusetts for new advanced energy storage to enhance the efficiency, affordability, resiliency and cleanliness of the entire electric grid by modernizing the way we generate and deliver electricity. In order to increase energy storage deployment, this Study presents a comprehensive suite of policy recommendations to … [Read more...]

Integrated Distribution Management Systems

In this report, we present the architecture of an integrated electric distribution system management approach based on the coordinated operation of a DMS, MCs, DERMS, and DERs. The relevant DER group functions necessary to support the implementation of selected DMS applications, i.e., OLPF, VVO, FLISR, SCA and DR, are identified; and messages for … [Read more...]

How to Optimize Energy Storage in a Microgrid

In this paper, new voltage sensitivity indexes are proposed which can help you optimize energy storage in your microgrid. These indexes are derived from the inverse Jacobian matrix from the Newton-Raphson power flow analysis. After calculating and evaluating these indexes for the studied microgrid, four candidates‘ buses are selected. To verify … [Read more...]
