ISO-NE marks Earth Day with an update on energy-efficiency, solar, and wind resources in New England

Region is on its way to meeting states’ “green power” goals

As the world marks the 45th annual Earth Day on Wednesday, April 22, New Englanders can take note of widespread efforts across the six-state region to develop cleaner sources of electric energy and reduce electricity use. ISO New England has been working closely with both the states and industry stakeholders to help quantify and integrate regional developments related to energy-efficiency (EE) programs and wind and solar resources, two renewable sources of power.

Wholesale electricity prices and demand in New England

March average prices for natural gas and wholesale power dropped by half from February’s high levels

The advent of milder spring weather, which helped reduce demand for natural gas for heating and alleviated constraints on New England’s natural gas pipelines, brought lower natural gas and wholesale electricity prices during March. Average wholesale electric energy prices and natural gas prices both dropped during March by more than 50% from February’s averages, which were the fourth-highest average prices for both wholesale electricity and gas since 2003.

The average wholesale electric energy price in New England during March 2015 was $57.93 per megawatt-hour (MWh)*, down 54% from the February 2015 average price of $126.70/MWh, and down 50.1% from the March 2014 average of $116.12/MWh. The average natural gas price declined by 53.3% from February’s average price.

ISO-NE’s Microsoft web browser policy for SMD applications changing this year; to support only Internet Explorer 11 beginning January 2016

In the fall of 2014, Microsoft announced that starting January 2016 they will support only the most current version of Internet Explorer (IE) web browser available for a supported operating system. This means that for the Windows 7 operating system, they will support only IE version 11. This transition poses some challenges to how ISO New England supports its SMD applications because Microsoft allows only one version of IE installed on Windows (in other words, you can't have IE version 8 and 11 on your PC). The ISO has worked to develop a plan to adjust the support of its varied SMD applications that will cause the least amount of inconvenience to market participants. Over the course of 2015, the ISO will modify many of the SMD applications to support both IE11 and the currently supported IE8 (and IE9 in cases where it is presently supported as noted in the web browser support for SMD applications policy). For applications that cannot be modified in this manner, the ISO will continue to support IE 8 (and IE9 if currently supported) until January 2016 and then only IE11 after that. The ISO will notify market participants of the migration dates and when outages will occur through our customary notification mechanisms.

Beginning January 2016, the ISO will support only IE11 for SMD applications. While other browsers may be used and work appropriately for some applications, we recommend that market participants using SMD applications plan to update their browser to IE11 that month.
