Westminster, which has its own electrical utility, also allows net metering. New Brunswick allows net metering for installations up to 100 kW. Credits from excess generated power can be carried over until March at which time any excess credits are lost. SaskPower allows net metering for installations up to 100 kW. Credits from excess generated power can be carried over until the customer's annual anniversary date, at which time any excess credits are lost. In Nova Scotia, in 2015, 43 residences and businesses began using solar panels for electricity. By 2017, the number was up to 133. These customers’ solar systems are net metered. The excess power produced by the solar panels is bought back from the homeowner by Nova Scotia Power at the same rate that the utility sells it to its customers. “The downside for Nova Scotia Power is that it must maintain the capacity to produce electricity even when it is not sunny.” European Union Denmark established net-metering for privately owned PV systems in mid-1998 for a pilot-period of four years. In 2002 the net-metering scheme was extended another four years up to end of 2006. Net-metering has proved to be a cheap, easy to administer and effective way of stimulating the deployment of PV in Denmark; however the relative short time window of the arrangement has so far prevented it from reaching its full potential. During the political negotiations in the fall of 2005 the net-metering for privately owned PV systems was made permanent. The Netherlands has net-metering since 2004. Initially there was a limit of 3000 kWh per year. Later this limit was increased to 5000 kWh. The limit was removed altogether on January 1, 2014. Italy offers a support scheme, mixing net-metering and a well segmented premium FiT. Slovenia has annual net-metering since January 2016 for up to 11 kVA. In a calendar year up to 10 MVA can be installed in the country. In 2010, Spain, net-metering has been proposed by the Asociación de la Industria Fotovoltaica (ASIF) to promote renewable electricity, without requiring additional economic support. Net-metering for privately owned systems will be established in 2019, after Royal Decree 244/2019 was accepted by the government on April 5. Some form of net metering is now proposed by Électricité de France. According to their website, energy produced by home-owners is bought at a higher price than what is charged as consumers. Hence, some
