'In March, during the hours of 8am to 2pm, system average hourly prices were frequently at or below $0 per megawatt-hour'Surfer Cole Clisby rides his surfboard off the top of a wave as the sun sets off the shores of Leucadia, California"Yeah, they're out there havin' fun, In the warm California sun," sang The Rivieras in their 1964 hit.And it could not be more apt today as the sun in the state was so strong – and the number of solar farms so large – that electricity prices in the state have begun turning negative on the main power exchange, the US Energy Information Administration (EIA) has revealed.Solar made up a record figure of nearly 40 per cent of the electricity sent to the grid in the California Independent System Operator’s (CAISO’s) territory for a few hours on 11 March, after utility-scale solar farms grew by almost 50 per cent in 2016, the EIA said on its website.However, as the Quartz website pointed out, negative wholesale prices do not translate into an unexpected windfall for consumers.This is because retail prices are based on the average cost, so people might get slightly cheaper electricity but not an actual cash payment as a result of prices becoming negative for a few hours.The EIA said: “The large and growing amount of solar generation has occasionally driven power prices on the CAISO power exchange during late winter and early spring daylight hours to very low, and sometimes negative, prices.“However, consumers in California continue to pay average retail electricity prices that are among the highest in the nation.”Solar capacity in the state has grown rapidly in the last few years.There was less than one gigawatt in 2007, but nearly 14GW by the end of last year.At this time of year, the large amounts of sunlight and the relatively low demand can produce too much electricity around the middle of the day.“Electricity demand in California tends to peak during the summer months,” the EIA said.“However, in late winter and early spring, demand is at its annual minimum, but solar output, while not at its highest, is increasing as the days grow longer and the sun gets higher in the sky. “Although the sun is at a similar angle in September and October, electricity demand is still relatively high, leading to lower solar generation shares than seen in March.“Consequently, power prices … were substantially lower in March compared with other times of the year or even March of last year. “In March, during the hours of 8am to 2pm, system average hourly prices were frequently at or below $0 per megawatthour. http://www.independent.co.uk/news/world/americas/california-sun-solar-power-electricity-energy-prices-negative-renewables-green-climate-change-fossil-a7678086.html
Albuquerque city buildings getting $25M in solar panels Posted on Sunday, April 16th, 2017 By The Associated PressALBUQUERQUE, N.M. (AP) — New Mexico's most populous city has plans to install more than $25 million in solar panels on city buildings over the next two years.The installations in Albuquerque will mark the first phase in fulfilling a recently set goal of generating more of the city's energy from solar power.Albuquerque City Councilors Pat Davis and Isaac Benton made the announcement Saturday.They say the project's first phase of the project is expected to save taxpayers about $20 million over 30 years. City councilors last September passed a resolution calling Albuquerque to generate one quarter of its energy from solar power by 2025.The first phase of the project will begin later this year.The project will be financed through the energy savings and federal bond credits.https://www.marketbeat.com/articles/albuquerque-city-buildings-getting-25m-in-solar-panels-2017-04-16/
Do they mean 25% of their electric energy or 25% of total energy? Spend 25 mill to save 20 mill? Isn't that a net loss of 5 mill?
“The most exciting possibility is using this electrode with a solar cell, to provide a total on-chip energy harvesting and storage solution,” said PhD researcher Litty Thekkekara and lead author of the new study published in Scientific Reports.
“With this flexible electrode prototype we’ve solved the storage part of the challenge, as well as shown how they can work with solar cells without affecting performance. Now the focus needs to be on flexible solar energy, so we can work towards achieving our vision of fully solar-reliant, self-powering electronics,”
"With eight to nine hours of sunshine per day, the climatic conditions in Pakistan are ideal for solar power generation. According to studies, Pakistan has 2.9 million megawatts of solar energy potential besides photovoltaic opportunities.
