Solarcity/Tesla Pioneer Utility Scale Energy Storage System

SolarCity has selected Tesla Energy to supply the batteries for a first-of-its-kind solar array and energy storage system to be built for Kaua’i Island Utility Cooperative (KIUC). SolarCity made the selection after conducting a comprehensive competitive solicitation in the battery marketplace. The proposed SolarCity/Tesla project is believed to be the first utility-scale system in the U.S. to provide dispatchable solar energy, meaning that the utility can count on electricity being available when it’s needed, even hours after the sun goes down.

The 52 MWh Tesla Powerpack lithium-ion battery storage system will feed up to 13 megawatts of electricity onto the grid to “shave” the amount of conventional power generation needed to meet peak demand in the evening from 5 p.m. to 10 p.m. By using the solar energy stored in the battery instead of diesel generators, KIUC will reduce its use of imported fossil fuels and also cut its greenhouse gas emissions.

Under the terms of the 20-year contract announced in September 2015, KIUC will pay SolarCity 14.5 cents per kilowatt hour, only slightly more than the cost of energy from KIUC’s two existing 12 megawatt solar arrays, whose output is available only during the day. The array and battery storage facility will be built on 50 acres of land owned by Grove Farm Company, Inc. adjacent to KIUC’s Kapaia power station off Mā’alo Road, just north of Līhu’e.

The project has already received most of its required state and county approvals and is now awaiting approval by the Hawai’i Public Utilities Commission. KIUC and SolarCity have requested an accelerated timetable for review of the project so that construction work can begin by April with a goal of being in commercial operation by the end of 2016.

KIUC is a member-owned cooperative serving 33,000 customers on the island of Kaua’i. Formed in 2002 and governed by a nine-member, elected board of directors, KIUC is one of 930 electric co-ops serving more than 36 million members in 47 states.

SolarCity provides clean energy through residential, commercial and utility-scale solar systems and energy storage. The company claims to have disrupted the century-old energy industry by providing renewable electricity directly to homeowners, businesses and government organizations for less than they spend on utility bills.

Tesla Motors’ goal is to accelerate the world’s transition to sustainable transport with a full range of increasingly affordable electric cars. Palo Alto, Calif.-based Tesla designs and manufactures electric vehicles as well as renewable energy storage for residential and commercial applications.

Corporate Sourcing of Renewables Growing, Taking Place in 75 Countries

Companies in 75 countries actively sourced 465 terawatt hours (TWh) of renewable energy in 2017, an amount close to the overall electricity demand of France, according to the report from the International Renewable Energy Agency (IRENA). With the continued decline in the costs of renewables, the report suggests, corporate demand will continue to increase as companies seek to reduce electricity bills, hedge against future price spikes and address sustainability concerns.

Arsenal Unveil Battery Storage System: First Of Its Kind At A UK Football Club

Arsenal Football Club has unveiled a battery storage system (BSS) to store enough energy to run the 60,000 seater Emirates Stadium from kick-off to full time. It follows a unique collaboration with Pivot Power to install a 2MW/2.5MWh lithium ion BSS, with funds managed by Downing LLP. The project, the first of its kind in the UK, will also save club money as it works to support low-carbon plans. The BSS allows Arsenal to avoid peak power prices, buying electricity when it is cheap and storing it for use when prices are high. Typically, energy can cost three times more at peak times than overnight. The installation maintains Arsenal as the leader in sustainability in sport following its commitment to clean energy with Octopus Energy in 2016.

Wind: China Maintains Emerging Markets Top Spot Following 19.7GW Build Boom

Wind industry intelligence service A Word About Wind has launched its Emerging Markets Attractiveness Index report for 2018, which provides insight and analysis into the most attractive emerging markets for wind companies. The index, now in its second year, ranks the top 30 emerging markets that investors should consider when investing in wind in Europe, Africa, Asia and Latin America. The list considers factors including political and economic stability for investors, alongside the growth of electricity demand and potential for wind growth, in order to rank the countries by overall potential. As with last year’s report, China tops the list and the ongoing trade war with the US shows no sign of slowing China’s formidable growth.
