The Business of Energy Management

See on Scoop.itGreen Energy Technologies & Development

When we look back on 2012, most of us will likely remember it as a year of extreme weather. In the summer particularly, record heat and drought coupled with a struggling economy had consumers doing all they could to find ways to save on energy.

Duane Tilden‘s insight:

# One of the most powerful tools does not have to be a piece of technology, but a strong management system. Companies should consider centralizing their data and creating incentives. |

# Alternative energy can also help in managing unpredictable energy prices. In the cost-conscious world of business, making these investments can be challenging in the face of the competitive business case process.  We have found success in these deals by combining financial variables – areas with high electricity rates and available financial incentives – with funding mechanisms like a Power Purchase Agreement (PPA) – to create steady electricity cost models that are competitive with current rate structures. |

Could IT Cut Greenhouse Gas Emissions by 16% by 2020? | The Energy Collective

Duane Tilden‘s insight:

"The Global e-Sustainability Initiative (GeSI), an information and communication technology (ICT) industry partnership, just released a new report that details how expanded use of ICT could cut global greenhouse gas (GHG) emissions by 16.5% by 2020 and offset $1.9 trillion in gross energy and fuel costs. …  Unsurprisingly, the power and transportation sectors, respectively, are found to have the highest potential for GHG emission reduction via greater ICT adoption. But the report also finds agriculture – even more so than manufacturing or the consumer and service sector – to be an area with significant potential for greater energy efficiency."

Why the green building industry needs to pay attention to tenants

See on Scoop.itGreen Building Operations – Systems & Controls, Maintenance & Commissioning

It’s time for the building industry to shift from develpment to maintenance, using a life cycle approach.

Duane Tilden‘s insight:

After buildings have been successfully commissioned and verified to be achieving their designed performance, they need to be operated in a manner that maintains that performance over time. Building re-commissioning is the practice of retuning a building every 5 to 7 years to bring its performance back in line with its design intent and technical capability. …

 

A well-instrumented building, and other buildings with interval utility meters, can be monitored using advanced analytical software to track energy performance and remotely detect faults in systems and equipment.

 

A systematic approach to improving building performance involves setting goals, establishing policies, defining metrics, developing action plans, tracking performance and reporting progress. As we have learned in recent projects, the timing of improvement actions — from retro-commissioning to opportunistic equipment upgrades to major retrofits — are critical to achieving significant efficiency improvements with the best financial returns.

Ten Ways to Slash Energy Costs in your Organization

See on Scoop.itGreen Building Operations – Systems & Controls, Maintenance & Commissioning
Whether you’re a for-profit business or a non-profit municipality, your bottom line matters. Your bottom line determines whether or not you continue

Duane Tilden‘s insight:

"…So what exactly does energy management software do? “Energy tracking” says it best. Energy management software tracks utility bills, and in doing so spots abnormal trends and suspected billing and metering errors. Some programs also track 15-minute electric meter load data, which can provide valuable insights into near real-time usage patterns and expensive power leaks.

By compiling a database of utility bills, energy management software puts the power of information at your organization’s fingertips. Comprehensive energy management software ought to help you slash energy costs, comprehensively. Here are ten ways energy management software protects your bottom line:  …"

Emerson Process Management, a global business of Emerson (NYSE: EMR), has been selected to provide its Ovation™ control and optimization technol

Duane Tilden‘s insight:

"…

The 110-megawatt (MW) Catalina Solar and 140-MW Pacific Wind projects are located in Kern County, California."

 

Emerson’s Ovation system will play a key role in adjusting electrical output as directed by the California Independent System Operator (CAISO) – a task that is becoming more important as renewable energy sources provide an increasing share of electricity to the grid. …"

Cannibalization in Renewable Energies

See on Scoop.itGreen & Sustainable News

If you read the reports from major energy agencies and industry associations, you might be tempted to conclude there is a bright future where all types of renewable energies will flourish and coexist peacefully. Well, they will not. Much like in any other sector, some technologies will trump others. In this two-part article, we analyze how solar photovoltaic (PV) is beating concentrated solar power (CSP), and how offshore wind is doing the same to wave energy.

How to Install and Use an Energy Management System – Sustainable Plant

See on Scoop.itGreen Building Operations – Systems & Controls, Maintenance & Commissioning

For facilities with hundreds of devices to manage, monitor and track, a central system is required to pool data from the device, circuit or load into understandable, actionable information. Energy management software trends data to manage expenses across a facility, making it possible to compare equipment or facility energy consumption and identify inefficient practices. Software calculates the return on changing habits, replacing equipment.

ROI: How to Justify the Cost of an Energy Monitoring System | Sustainable Plant

See on Scoop.itGreen Building Operations – Systems & Controls, Maintenance & Commissioning

You can’t calculate ROI of a metering system any more precisely than you can for a financial accounting system, but experience shows energy monitoring always leads to reducing consumption by 10 to 20 percent or more.

Duane Tilden‘s insight:

"…. In several of our projects, energy costs for the total facility were reduced 40% or more with no capital improvements required; the savings resulted entirely from changes in accountability, responsibility, operation, maintenance and control that were only possible because of the data from the monitoring system. …."

 

"There are no magic bullets, no simple solutions for complex problems as so many would like to believe. Energy use in large buildings and systems is very complex. My advice is to return to the fundamentals of good engineering problem-solving and financial management: start by installing instrumentation, gather the actual information, the facts, then view energy as dollars; treat energy management as financial management and integrate it with your existing financial management and accounting system."

Utility Dominion Buys Big into Fuel Cells

See on Scoop.itGreen & Sustainable News
Stationary fuel cells have been steady performers for years delivering electricity at office parks, supermarkets, or wastewater treatment plants. But utilities, for the most part, have stayed clear of fuel cells.

Richmond, Virginia-based Dominion today said it will own and operate a 14.9-megawatt fuel cell power generation station in Bridgeport, Connecticut. Supplier FuelCell Energy claims it will the first publicly-traded utility in North America to use fuel cells for distributed power generation into the grid.
