New Hampshire

New Hampshire's Outdoor Lighting Efficiency Act (HB 585) — sponsored by a bipartisan group of state legislators and backed by conservation groups, town planners and a leading utility — became law on September 13, 2009.

HB 585 does these four things:

• Requires all new and replacement outdoor lighting (including roadway lighting) installed with state funds to be fully shielded, "dark-sky friendly," and not to exceed minimum lighting levels recommended by the Illuminating Engineering Society of North America (IESNA.)

• Requires utilities to provide fully shielded dark-sky compliant streetlight fixtures to New Hampshire municipalities as the default option, although local communities can choose other designs if they wish.

• Tells the Public Utilities Commission to set a "midnight service" rate for streetlighting that allows utilities to install timers on non-essential lights selected by municipalities to be turned off at midnight, to reduce energy consumption by half.

• Establishes a statewide policy of protecting New Hampshire dark skies as a cultural asset important to rural character and the tourism industry.
