WIND SPEED

Friday, April 6th, 2012

Continuing the theme of WIND POWER, one of our members sent in this link to an amazing new art project that shows, in real-time, the surface wind speeds over all of the United States.  Surface wind data comes from the National Digital Forecast Database.  You can zoom in on the map to see more detail.

WIND POWER II

Friday, March 16th, 2012

Since the first WIND POWER blog two weeks ago, we have received over 20 phone calls and in person questions about these two systems. It is true that wind power is on the minds of local islanders!

Here is a summary of the questions we have received and answers we compiled:

For ease, Turbine 1 is the tall turbine system on Lopez and Turbine 2 is the round turbine system on Orcas.

Q. What are the sizes in kW of the wind turbines?
A. Turbine 1 is 10 kW and Turbine 2 is 2.5 kW

Q. How much energy per year will the turbines produce?
A. Turbine 1 is estimated to produce 12,000kWh per year.  Turbine 2 is estimated to produce 3,000kWh per year. Our average member uses approximately 800 kWh per month.

Q. How were these turbines permitted?
A. Turbine 1 was very costly and time consuming to permit because of its height at 120 feet. It was the first of its kind to go through the San Juan County permitting process and actually helped pave the way for future wind systems. Turbine 2 was much simpler to permit as the height is only 35 feet.

Q. What is the name of the company that manufactures these turbines and how much do they cost?
A. Turbine 1 is manufactured by Xzeres (http://www.xzeres.com/). We do not have cost data on these particular systems but a wind turbine of this type and height could be in the neighborhood of $100k. Turbine 2 is manufactured by Home Energy America (http://www.homeenergyamericas.com/energy-ball). One of these turbines would be in the neighborhood of $20k.

Q. What other resources are at these properties?
A. The Turbine 1 property also as solar PV. The Turbine 2 property has a geothermal heat pump and is planning to add solar PV.

Please direct your additional questions about these wind systems or any renewable energy systems to the OPALCO Energy Services Department at 376-3571 or abertino@opaloc.com.

WIND POWER!

Friday, March 2nd, 2012

it is an exciting time for small scale wind power in San Juan County. Two very different wind turbine systems have recently connected to the OPALCO grid.  The first is the somewhat traditional looking 120’ turbine on Lopez manufactured by Xzeres. This 10kW system is expected to produce over 12,000 kWh per year. The second installation is the two turbine, futuristic looking Earth Ball system on Orcas.  These turbines are manufactured by Home Energy America and are rated at 2.5kW each. The expected yearly output for each Earth Ball is 3000kWh.

Both owner-members have signed up for the MORE (Member Owned Renewable Energy) program and will be receiving a production incentive funded by the voluntary contributions of other Co-op members who support local renewable energy generation.  If you want to support the MORE program, check the box on your paper bill or call in to let us know at 376-3500.

The OPALCO Energy Services staff will be monitoring these new wind systems along with their owners for performance numbers. We will report back in six months with the data.

A SECOND LIFE FOR EV BATTERIES

Thursday, February 9th, 2012

From smartgridnews.com: Unlike standard car batteries, lithium-ion batteries used to power EVs have a lot of life left in them after they’re retired from service in a vehicle. Automation technology group ABB, Nissan North America, 4R Energy and Sumitomo Corporation of America have teamed up to evaluate and test the all-electric Nissan Leaf battery for residential and commercial use as energy storage systems.

Lithium-ion batteries have up to 70% of their capacity remaining after 10 years of service as a car battery. The partners plan to create a Leaf battery storage prototype capable of providing at least 50 kilowatt hours of power, the amount needed to keep the lights on in 15 average homes for two hours.

Ahhhhhhh!!!!!! How did I use so much electricity last month?

Wednesday, January 25th, 2012

Why did I use more than last year at this time? Hasn’t it been warmer this year?

These are questions we get a lot this time of year.  Often, after some investigation, we find the answers together.

For example: to answer “Why did I use more than last year at this time? Hasn’t it been warmer this year?

Guess what? This past December hasn’t been warmer than last year.  We think it has, myself included, but here are the average December temperatures for the last three years:

Dec 2009   37 deg
Dec 2010   43 deg
Dec 2011   40 deg

Here’s another example:  “How did I use so much electricity last month?”
Check out the blog post from December 14th.  ( IT’S ALL ABOUT HEATING NOW ) If you heat with electricity, like I do, your bill has gone up 3 or 4 times since the summer.   That’s how it is if I don’t want to wear a parka indoors!

What are some other culprits that cause our homes to use more electricity this time of year?
1. Not using window coverings. Windows are like holes in the wall.  If you cover them, less of the heat ($$) from the room will go out the window.
2. Attic access doors which are not sealed and insulated. Heat ($$) rises right out the roof if you let it.
3. Emergency heat strip settings on thermostats. Did it accidently get left on? You should never put your heat pump in that mode unless your heat pump is not keeping the house warm. Heat strips will consume about 3 times as much electricity as the heat pump alone. This is different than the auxiliary heat mode which comes on usually when the temperature falls below 35 deg.
4. Close the fireplace damper tightly when you are not using it. It’s just like an open window!
5. Lighting. It’s dark outside and our lights are on longer. Did you know CFL bulbs  use one quarter the energy of incandescent bulbs but provide the same amount of light?
6. Hot Tubs. No explanation needed.

Always remember we are here for you. Now that OPALCO has completed the rollout of digital Automated Meter Reading meters, our Member Services team can review your daily consumption trends with you to try to pinpoint your heating and other high consumption sources. Also, reads can now be pulled just a few days before billing.  This means billing periods may not be consistent year over year for comparison.  Always remember to pay close attention to the reading dates and “Days Served” on your bill when comparing historical consumption.  See Understanding Your OPALCO Bill for a visual explanation of you bill.

Our Energy Services Department can help you with a more in depth investigation of your home. Consider a Home Snap Shot Energy Assessment by one of our Building Performance contractors.

 

Electric Vehicles: the “electric highway” and end of tax credits

Thursday, January 12th, 2012

As seen in the Seattle Times this weekend: The first fast-charging station in the Washington’s “Electric Highway” is being installed at the Sehome Village Shopping Center in Bellingham. Also – a tax credit that allowed Americans to deduct 30 percent of the cost of electric car chargers installed in their garages has expired. Read the full articles

While You Were Enjoying the Holidays –

Thursday, January 5th, 2012

Congress decided to temporarily halt the enforcement of new light bulb efficiency standards. Here is one article on the subject from Electric Co-op Today.  What does this mean for you?  You will still be able to buy a 100 watt incandescent light bulb in 2012, but why would you?

It’s all about heating now!

Wednesday, December 14th, 2011

 

Over the summer I figured out that my home’s base load electricity usage was around 17kWh per day.

I gave the definition of “electricity base load” as the amount of electricity used in providing routine needs for your household, such as operating everyday appliances and electronics including the water heater. The base load usage does not include the seasonal load of heating.

The official start of winter is only a few days away, but I turned on my heating system October 3rd, and my electricity usage has gone steadily up as the temperatures have gone down.

How much electricity is it taking to heat my 1600sf house?  Of course there are many variables to consider including the inside temperature setting and whether or not I have the wood stove burning.

On average, since I turned the heat on October 3rd, my usage has gone up to 57 kWh per day from the 17 kWh per day in the summer. That’s over three times as much.  Now in December the average is 71 kWh per day and that’s 4 times as much.  When I have the wood stove burning in the evenings the usage goes down between 10 kWh and 15 kWh per day.

How does this translate to my OPALCO bill?  Easily, it’s gone up and it’s gone up in proportion to how much electricity I’m using to heat my home. Yes, that means 3 to 4 times as much as the summer bill! Oh, and don’t forget, some of the usage is due to more lighting on these dark evenings.  It’s just a few more days until the shortest day of the year.

Ho, Ho, Ho Hum – Welcome to winter!

Holiday Lights: Be Safe. Be Efficient. Go LED.

Tuesday, November 29th, 2011

If all decorative light strings sold in America this year were ENERGY STAR qualified, we would save over 700 million kWh of electricity per year and reduce greenhouse gas emissions equivalent to those from about 100,000 cars! Many ENERGY STAR qualified decorative light strings feature LED technology. What is an LED?

  • Light emitting diodes, or LEDs, are small light sources that are illuminated by the movement of electrons through a semiconductor material.
  • LEDs are exceptionally energy efficient when producing individual colors, many using up to 90% less energy than an incandescent bulb to produce the same amount of light.
  • For example, the amount of electricity consumed by just one 7-watt incandescent bulb could power 140 LEDs — enough to light two 24-foot (7.3-meter) strings.
