Paula Gant Natural gas key to Wellinghoff vision

The Chairman of the Federal Energy Regulatory Commission, Jon Wellinghoff, recently made news by suggesting that there may never be a need for a new nuclear or coal power plant to be built in the U.S.  Chairman Wellinghoff envisions a future in which renewable resources such as wind, solar, and hydrokinetics are backed-up by natural gas-fired generation — central and distributed facilities — which will provide load-response services.  If this potential were fully realized, coal and nuclear could theoretically be priced out of the market, potentially making baseload generating capacity a thing of the past.  A robust electric transmission system, demand response programs — “smart” grid — and increased energy efficiency would be an important part of the picture.  Chairman Wellinghoff raises a very important point regarding the economics that support this vision — expectations of ever-higher construction costs and increased siting challenges associated with new coal and nuclear plants are changing thinking about the relative cost equation comparing traditional central generation plant and distributed resources — renewable or other.  This shift in thinking on the part of leading policymakers is representative of the sea change that is occurring in thinking about how and where we produce energy.

Natural gas will play an important role in enabling this “smart” vision whether through traditional uses in space and water heating, or in the production of electricity inside of or nearer to homes and businesses.  As part of the state-wide New Jersey Clean Energy Program, natural gas utilities in that state administer Pay for Performance, which provides incentives of up to $1 million to industrial and commercial customers for purchasing and installing Combined Heat and Power (CHP) units.  This emerging technology is expected to become increasingly prevalent as an innovative way to enhance energy efficiency through recovery and productive use of waste heat, thus reducing both demand on the electric power grid and carbon dioxide emissions. And although it’s not yet ready for the mass market, even micro CHP (the smaller version designed for residential use) is beginning to earn some attention.

In short, Chairman Wellinghoff is definitely on to something “smart” and natural gas will be key to his vision becoming a reality.

Paula Gant Residential natural gas efficiency effort underway in New York

As energy efficiency begins to take center stage in federal legislation (the premier example being the Waxman-Markey draft bill currently under consideration in the House), it’s easy to forget that on matters of climate and energy states have long been the leaders in implementing energy efficiency solutions, and utilities have been at the forefront in partnering with regulators and customers to deliver energy efficiency gains.  These efforts are really ramping up – even prior to the infusion they stand to receive from the stimulus funds.

A great example of state-level energy efficiency activity was recently announced by the New York State Public Service Commission (NYPSC).  As part of its Energy Efficiency Portfolio Standard (EEPS) proceeding, the Commission has approved a natural gas efficiency equipment program for its nearly 4.3 million residential gas customers.  Under this action, more than $24 million will be made available for rebates promoting the purchase and installation of efficient, cost-effective, furnaces, boilers and other equipment.  This is great news for consumers, as it will provide a direct financial incentive to improve energy efficiency in their homes – savings that come in addition to the money they will save over time in reduced energy costs.

The action taken by the NYPSC recognizes the important role local utilities will continue to serve in delivering energy savings to residential customers.

The utilities participating in this initiative include Central Hudson Gas and Electric Corporation, Consolidated Edison Company of New York, Inc., Corning Natural Gas Corporation, KeySpan Energy of Long Island, KeySpan Energy of New York, New York State Electric and Gas Corporation, National Grid, Orange and Rockland Utilities, Inc., Rochester Gas and Electric Corporation, and St. Lawrence Gas Company.

Paula Gant Thoughts from the briefing for Congressional staff on renewable natural gas

The briefing on renewable natural gas to Congressional staff we did earlier in the week went very well. I am very pleased we got an opportunity to continue educating others about the options we have using renewable natural gas and our existing distribution network.

Here is a powerpoint from Chris Voell of the Environmental Protection Agency titled, “Renewable Biogas: Environmental Protection and Energy Independence.” You can download the full pdf here. It’s a large file so it may take a moment.

I’ve pulled out some interesting graphics and stats for a quick view.

Some stats on the projects include:

  • 450 electricity generation
  • 135 direct use (medium Btu)
  • 25 high Btu pipeline quality gas
    • AR, CA(2), GA(2), KS, LA, MI(2), NY, OH(3), PA(8), TN, TX(3), WI
    • Less than 5% of total projects
  • GHG reductions from currently operating methane capture and use projects:
    • Direct Methane – 3.5 million metric tons CH4/year
    • Avoided CO2 – 9 million metric tons CO2e/year
    • Total Reductions – 80+ million metric tons CO2e/year
  • Environmental equivalent to reducing CO2 emissions from:
    • More than 200,000,000 barrels of oil consumed, or
    • Nearly 16,000,000 passenger vehicles, or
    • Burning more than 450,000 railcars’ worth of coal.
  • Energy equivalent to:
    • Powering more than 915,000 homes and heating more than 700,000 home

Paula Gant Briefing for Congressional staff on renewable natural gas

090323biogas Briefing for Congressional staff on renewable natural gas We’re working with the Business Council for Sustainable Energy and the Gas Technology Institute to provide a briefing for Congressional staff on renewable natural gas tomorrow. Renewable natural gas is an important part of the portfolio of clean energy solutions. But what is renewable natural gas you say?

Renewable natural gas is a biogas which has been upgraded to a quality similar to natural gas. One of the attractions of renewable natural gas is that by upgrading the quality to that of natural gas, it becomes possible to distribute the gas to customers via the existing gas grid, and burned within existing appliances.

We’ve had biogas on our radar for a while. A growing number of our members are interested in this energy option.

As are some really big energy players like Royal Dutch Shell.  This energy giant announced just last week their decision to discontinue investment in renewable technologies such as wind, solar and hydro power because they feel they are not economic. Instead Shell plans to invest more in biofuels – like renewable natural gas — which do not use food-based crops and are less harmful to the environment.

I’ve actually written on biogas before on this blog but here’s a little more information. Biogas originates from biogenic material and is a type of biofuel. One type of bio-gas is produced by fermentation of biodegradable materials such as biomass, manure or sewage, municipal waste, green waste and energy crops. The other principal type of biogas is wood gas which is created by gasification of wood or other biomass.

Biogas can be used as a low-cost fuel for any heating purpose, such as cooking. Biogas can also be used in modern waste management facilities where it can be used to run any type of heat engine, to generate either mechanical or electrical power. Biogas can be compressed, like natural gas, and used to power motor vehicles.

Leave a comment if you have questions on biogas and I’ll be happy to try and answer them. I’ll also write later about my thoughts on the briefing. We are excited about the opportunity to continue educating others about the options we have using renewable natural gas and our existing distribution network.
