Summary

Note: On October 12th, 2015 the Hawaii PUC voted to end net metering in favor of 3 alternative options: a grid supply option, a self-supply option, and a time of use tariff. Customers with net energy metering application submitted before October 12th will have the option of continuing with net metering described below.

Community renewable energy tariffs have been proposed by Hawaiian utilities pursuant to SB 1050 and are currently being reviewed.

Eligibility and Availability

Net metering is available on a first-come, first-served basis to residential and “small commercial” customers (including government entities) that generate electricity using solar, wind, biomass or hydro-electric systems. Third-party owned and operated systems are eligible to participate in net metering (leased systems and systems with a third-party power purchase agreements can participate in net metering). Under the terms of the March 2008 and December 2008 PUC orders, Hawaii’s three investor-owned utilities (HECO, HELCO and MECO) and sole electric cooperative (KIUC) have slightly different programs:

For customers of Hawaiian Electric Company (HECO), the maximum individual system capacity is 100 kW. The aggregate capacity of net-metered systems is limited on a per-circuit basis to 15% per circuit distribution threshold for distributed generation penetration. Of this 15% in peak circuit demand capacity, 5% (or 0.75% of overall peak circuit demand capacity) will be reserved for residential or small commercial systems that are 10 kW or smaller.

For customers of Hawaii Electric Light Company (HELCO) and Maui Electric Company (MECO), which are both subsidiaries of HECO, the maximum individual system capacity is 100 kW. The aggregate capacity of net-metered systems is limited on a per-circuit basis to 15% per circuit distribution threshold for distributed generation penetration. Of this 15% in peak circuit demand capacity, 5% (or 0.75% of overall peak circuit demand capacity) will be reserved for residential or small commercial systems that are 10 kW or smaller.

For customers of Kauai Island Utility Cooperative (KIUC), the maximum individual system capacity is 50 kW. The aggregate capacity of net-metered systems is limited to 1% of KIUC’s peak demand. Of this 1% limit, 50% is reserved for systems 10 kW or smaller.

Net Excess Generation

The March 2008 PUC order also required each utility to develop a pilot program allowing net metering to a limited number of systems 100 kW to 500 kW in capacity, while allowing for even larger systems “if technically and economically reasonable and practicable.” KIUC currently has a pilot net metering program for systems up to 200 kW. Under the pilot program, customer-generators will be paid $0.20 per kilowatt-hour (kWh) for a system’s net excess generation at the end of each year. Participants can receive this payment for net excess generation for a 20 year term.

A customer whose system produces more electricity than the customer consumes during the month may carry forward NEG in the form of a kilowatt-hour (kWh) credit that is applied to the customer’s next bill. NEG may be carried over for a maximum of 12 months. At the end of the 12-month period, any remaining customer NEG credits are surrendered to the utility without compensation (unless the customer enters into a purchase agreement with the utility).

Virtual Net Metering/Community Solar

SB 1050 mandates that utilities propose community renewable energy tariffs by October 1st, 2015. The tariffs must:

  • Allow an electric utility customer to participate in an eligible project
  • Be designed to provide fair compensation for electricity, electric grid services, and other benefits provided to or by the electric utility, participating ratepayers, and non-participating ratepayers
  • Allow the electric utility to implement a billing arrangement to compensate customers for electricity and grid services
  • Standardize and streamline interconnection processes for community-based renewable energy projects.

Any entity with an eligible facility that meets compliance requirements can become subject to a community renewable energy tariff.

History

Hawaii’s original net-metering law was enacted in 2001 and expanded in 2004 by HB 2048, which increased the eligible capacity limit of net-metered systems from 10 kilowatts (kW) to 50 kW. In 2005, the law was further amended by SB 1003, which authorized the Hawaii Public Utilities Commission (PUC) to increase certain limits outlined in the law and provided for the carryover of net excess generation (NEG) to the customer’s next bill. In March 2008, the PUC issued an order to implement SB 1003. This order generally raised both the individual system capacity limit and the aggregate capacity limit for net-metered systems. In October 2008, Hawaii’s governor; the Hawaii Department of Business, Economic Development and Tourism; the Hawaii consumer advocate, and the HECO companies entered into an energy agreement, a product of the Hawaii Clean Energy Initiative. This agreement provides that there should be no system-wide caps on net metering, and that net metering should transition towards a feed-in-tariff. In December 2008, the PUC issued an order to raise the aggregate capacity limit for net-metered systems in the service territories of HELCO and MECO. In January 2011, the PUC issued an order approving changes to Kauai’s program, which was full, and the aggregate capacity limits for HECO companies were lifted and are now based on per-circuit caps rather than a percentage of peak demand.

Summary

Note: On May 12, 2015 Georgia’s governor signed House Bill 57 which allows residential and commercial customers to enter into third party financing deals for solar systems.

Georgia Power does not offer a net energy metering tariff. Net energy metering tariffs filed by cooperatives are recorded in Docket # 31536 on the Georgia Public Service Commission’s website. Customers should contact their utility to see if it offers net metering.

The Georgia Cogeneration and Distributed Generation Act of 2001 allows but does not require net energy metering to be adopted by utilities. The law requires all utilities — investor-owned utilities, municipal utilities and electric cooperatives — to offer bidirectional or single directional metering to customer generators, depending on how the customer’s facility is connected to the grid. Eligible technologies include photovoltaic (PV) systems, fuel cells and wind turbines up to 10 kilowatts (kW) in capacity for residential applications, and systems up to 100 kW for commercial applications. The aggregate capacity of such systems is limited to 0.2% of a utility’s system peak demand from the previous year.

Systems connected on the customer’s side of the meter use a bi-directional meter, and any net excess generation (NEG) is credited to the customer’s next bill at a predetermined rate filed with the Georgia Public Service Commission (this is currently the Solar Avoided Cost for Georgia Power) . Alternatively, a customer may choose to sell all electricity from a system (rather than using the electricity generated by the system) by connecting ahead of the meter.

HB 57 allows residential and commercial customers to work with third parties to install, operate, lease, and/or finance solar systems. The limit for residential customers is 10 kW and the limit for commercial customers is 125% of the actual or expected peak demand of the premises. All systems must meet applicable safety, power quality, and interconnection requirements. Commercial systems above 100 kW and residential systems above 10 kW are not explicitly prohibited at this time but may be subject to additional compliance requirements.

36KW Wind Turbine, Power Produced Each Month

The charts below gives a rough estimate of the power produced each month by Change Wind Corporations 36KW Helical Wind Turbine, and by a rough estimate I mean, the wind changes daily and your not going to get a wind to blow steadily at 10mph for a whole month.

 The main reason for the chart is to show how much electricity can be produced each month which is a lot, and that’s in the present time, what will it be 5 years from now or 10-20 years from now.

The cost per kilo watt hour has risen 30% or more in much of the USA over the past 10 years, some places a lot more then 30% and costs will continue to rise as coal mines are shut down and demand continues to rise.

Take the numbers from the chart and add about 50% more to that total and that’s the amount of power Change Winds 36KW wind turbine will produce 10-15 years from now.

Frequently Asked Questions

What is the cost per kW of CWC’s turbines compared to conventional power technology?

The CWC 36kW cost is $2013 per kW of power production capacity. According to the AWEA, the average cost for electricity production capacity in the USA is $6096 per kW —- 303% higher.

Who is CWC’s competition?

We are aware of 334 companies in the small wind turbine space. Most of them only produce very small turbines (under 10kW).  None of them price their electricity production capacity anywhere as low as Change Wind’s price ($2013 per kW,  i.e. $72,440 per turbine).

Is the CWC 36kW competitive with 3-blade horizontal axis turbines? 

Yes, very much so.  On a cost per kW basis, the CWC 36kW sells for 72% below the competition in small and medium turbines.  It pruduces electricity using turbulent air only 10 meters over the surface, cutting in at just 6 mph, and reaching optimal efficiency at 12 mph.  Since it captures wind from any direction it does not have to be mechanically turned into the wind direction.

Are there any service issues I should be concerned about?

The CWC 36kW comes with a 10 year warranty which can be extended an additional 10 years as long as the annual maintenance has been carried out. The turbine needs an inspection, oil change, lubrication, electronics check, and power wash every 100,000 kWh, approximately once each year, costing roughly $500 in most areas.

How is Change Wind able to price its turbines so low?  

Change Wind passes along to customers the benefit of high efficiency and low cost manufacturing.   Production is performed at a re-purposed New England wire factory building obtained at below market cost, with on-site hydro-electric power at 66% below market cost.  The company uses state-of-the-art CNC and robotic machinery, extracting its craftsmanship from the sophisticated machinery and tools, not from expensive workmen.

 

Are there tax incentives for on-site wind systems?

On October 3, 2008, the Emergency Economic Stabilization Act of 2008, H.R. 1424, was enacted into law.  It includes a federal-level investment tax credit to help consumers purchase wind turbines for home, farm, or business use.  Owners of systems with 100 kW of capacity or less can receive a credit of 30% of the installed cost of the system.  It is available for equipment installed through December 31, 2016.  Source: http://energytaxincentives.org/business/renewables.php.
