Boston Natural Gas Prices Spike in December

December Natural Gas Prices in Boston

Boston saw natural gas prices spike in December. In a recent notice, the United States Energy Information Administration (EIA) shows that bidweek natural gas prices for December 2013 were nearly triple the November prices. The December settled at $14.52 per million Btu which compares to under $4 in October and $10 last December. The December 2013 prices are the highest ever recorded at the Algonquin hub that serves Boston. Nationally, prices have not risen to this degree. Factors contributing to the price spike include: pipeline/delivery constraints, cold weather in November, forecast below normal temperatures in December and maintenance downtime for secondary delivery systems. The full EIA report is available here.  Residential and commercial natural gas prices will inevitably rise in response to the increased cost for the Utilities to buy gas on the open market. Since about 40% of building energy expense is space heating, natural gas customers should plan for increased natural gas prices this winter. It looks like New England will not be able to sustain the low natural gas prices seen in recent years because of the limited pipeline capacity. The reasons for this are in the second EIA chart and our interpretation, below.

Delivery Infrastructure Problem

New England has infrastructure problems that limit delivery. There is simply not enough pipeline available to meet the expansion in natural gas demand that has occurred in recent years. Most of the natural gas entering New England is delivered via the Algonquin Gas Transmission pipeline system. This system has historically operated well below capacity except during peak demand. Because of increased natural gas use, the pipeline system has operated near capacity year round since 2011 and can no longer keep up with peak demand. Now,  demand peaks on top of the new normal monthly requirements can’t be met — especially if secondary delivery options are constrained. Constrained capacity results in increased natural gas prices. You can read more about the pipeline here. Here is a graph that shows how much demand for the pipeline has increased in recent years:

Geothermal Heating and Cooling Just Keeps Getting Better

Geothermal Heating and Cooling equals efficiency!  This is particularly true with the latest and most advanced 7 Series line introduced by WaterFurnace and provided by Achieve Renewable Energy.  This state of the art system is considered the ‘best of the best’ and represents the industry’s FIRST fully launched variable capacity residential unit and the ONLY unit to surpass both the 41.0 EER and 5.3 COP efficiency barriers developed by the U.S. Department of Energy.

WaterFurnace 7 Series

How does it work?  Unlike traditional geothermal units, which typically use one or two fixed compressor speeds, the 7 Series scales the speed up and down based on actual need.  This allows the system to run more frequently at lower capacity thus resulting in an increase in efficiency that translates into over 30% savings over a typical Geo system and up to 70% savings on a more traditional fossil fuel system. The 7 Series works like a race car with a 10 speed transmission while traditional units are limited to 1 or 2.

The current market place for these variable speed or inverter-based units is just starting to develop. The only inverter-based GSHP in production that is readily available is the WaterFurnace 7 Series. Competing units from other manufacturers are anticipated in the coming year or two but are not currently available. Achieve has installed or is currently installing more WaterFurnace 7 Series units than any other WaterFurnace dealer in our area and we believe we have the most inverter-driven GSHP experience of any geothermal installer in the Commonwealth of Massachusetts.

Tower School Solar PV Production Exceeding Expectations

Tower School PV Array

Electricity produced from Solar PV is the whole point of installing the solar panels, right? What can you do to maximize the production from your small commercial or residential PV system? Maybe you should talk to Achieve about designing your system with micro-inverters. The Tower School solar array went live in August of 2012 and we now have performance data for the first year. Achieve built this 25 kW Solar PV system with individual Enphase Micro-inverters for each of the 105 solar panels. The micro-inverters are designed to minimize impact due to shading. Micro-inverters also allow each solar panel to start producing electricity at the first sign of morning light. This maximizes solar PV production. Having each solar panel independent has great advantages over more common central inverters. Central inverters that connect solar panels like strings of old-style Christmas Tree lights — if one has a problem they all have a problem. Using standard industry software, the Tower School array was predicted to produce 28 mega-watt hours per year. In the first year, Tower School produced 32 MWh. That is over 14% more than predicted. Tower benefited with the extra 4,000 kWh produced and with an extra 4 Solar Renewable Energy Credits (SRECs). That’s about $1,550 in extra cash due to increased solar PV production. Was it the micro-inverters? Hard to say for sure. We do know using micro-inverters make monitoring and troubleshooting a breeze. The graph below shows solar PV production predicted for the Tower School array and the actual production. Not every month exceeded the predicted output. The lower winter half of the year (October to March) had several months with lower than predicted PV production. All of the summer half of the year (April to September) had higher output.

New Incentive on the way for Geothermal and SHW

There is a new incentive coming and this is a big deal for a lot of our clients because it creates an income stream from their renewable energy systems! Explaining things is a little regulation wonky we’ll try to be brief. If you have read our website then you know that there are tax credits and sales tax exemptions for geothermal systems Geothermal Drilling Rigand solar hot water (SHW). The tax incentives are great but the renewable thermal options have lagged behind solar PV in some states like Massachusetts. Those installations also qualify for Solar Renewable Energy Credits (SRECs) which are traded on an open market and provide ten years of income for owners of PV systems. Now both Massachusetts and New Hampshire are poised to be issuing renewable energy credits for each MWh of renewable thermal energy generated.

In Massachusetts, Senate bill S. 1593 is working its way through the legislature. The bill would include renewable thermal sources in the Solar Hot Water ArrayAlternative Energy Portfolio Standard. Achieve was at a meeting this week with Massachusetts Senator Downing who is the Senate chair for the Joint House/Senate Telecommunications, Utility and Energy Committee. Based upon discussion at the meeting, S. 1593 seems to be in a good position to move forward this year. Once the bill is passed, MassDOER will modify regulations to integrate renewable thermal technologies into the Alternative Energy Portfolio Standard (APS). There is an active set of regulation and trading system for the credits so adding in the renewable thermal technologies should not be too big a task. Achieve has had some informal discussions with regulators and expects the revised regulations will include a cutoff date for entering the program, an eligibility term, metering requirements and may have differing rules for residential and commercial projects regarding how the AECs are minted. One option that may be considered is providing owners of smaller systems a number of years of AEC ‘up front’ to further offset installation costs.

Rooftop Solar Array Enhances Curriculum at Tower School

Screen Shot 2013-08-21 at 9.10.05 PMTower School announces the completion of their rooftop solar array and the installation of electronic monitoring stations, which became fully operational during the 2012-2013 school year.

Board member, and driving force behind the solar program at Tower, Susan Livingston, expressed her commitment to the program, “As we try to move beyond burning fossil fuels as a nation, demonstrating the active use of renewable energy in schools sets a wonderful example for the community and our students. The new Solar Array can be a practical teaching tool for our children to learn more about our energy future.”

Head of School, Peter Philip agrees: “We are pleased to set an example for our students and for the community through the installation of this Solar Array. As well, we are eager to witness how our teachers and their students weave this commitment to renewable energy into the curriculum.”

The 105 solar module system was installed by Beverly MA-based, Achieve Renewable Energy, and is designed to supply more than 28,000 kilowatt-hours per year. Larry Lessard, director and founder of Achieve Renewable Energy, LLC says, “We’re proud to partner with Tower School in deploying a solar-electric system that will generate renewable, carbon-free power for decades. Our final phase is the installation of electronic monitoring stations within the science lobby, so the re- newable energy system can be integrated into the science program. To me that is the most gratifying part of the project.”
