Utility Integration

A common question for renewable developers interconnecting to a transmission system is whether they should pay more and procure a network resource interconnection service (NRIS) or pay less for energy resource interconnection service (ERIS)? The difference is this: A network service reserves transmission capacity on the grid for the renewable developer whereas an energy service...

Solar energy is figuring prominently in MISO utilities’ integrated resource plans. Recent announcements from MISO north region utility – Xcel Energy, and south region utility – Lafayette Utilities — show that both are considering utility-scale and distributed solar in meeting their future capacity needs. This solar capacity need is good news for solar developers. However,...

Midcontinent Independent System Operator (MISO) Board expects to approve a first interregional Market Efficiency Project (MEP) at its June 2020 meeting. Pennsylvania-New Jersey-Maryland Interconnection (PJM) Board already approved this project last December. This market efficiency project is a first for both MISO and PJM from a joint and common market perspective. MISO’s Transmission Expansion Plan...

Great River Energy (GRE) long-duration pilot project announcement generated many headlines recently. There were three things that the industry observers noted: 1) there is a new commercial grid-scale storage technology called aqueous air battery, 2) the pilot project is 150 hours duration and 3) GRE is retiring a baseload coal plant sooner than scheduled. Electric...

With the majority of the country’s workforce at home and most businesses and industries either operating at reduced capacity or temporarily shut down, COVID-19 has reduced electric demand across the board. This unprecedented drop in electricity consumption is reshaping the way the power system operates and forcing grid operators to revise forecasts and expectations for...

MISO voluntary capacity auction rarely makes news. But when it does, industry observers take notice. With $250 per MW-day, MISO Michigan zone 7 gives hope for developers in a vertically integrated state like Michigan. This capacity price is a good sign for renewable energy developers to enter into long term Power Purchase Agreements (PPAs). Remains...

New York Independent System Operator (NYISO) received FERC approval for its dual participation model. Dual participation refers to resources that participate in both wholesale and retail markets. This model has positive benefits for distributed energy resources, including aggregated energy storage. NYISO’s model leverages existing bid rules within energy, capacity and ancillary services market structures. Grid...

Solar developers have already added storage at solar interconnection locations, but MISO needs to do its part in approving those requests. Once MISO starts calculating solar capacity credit in 2020 fall, the value will be less than the current 50%. There are three reasons why MISO should prioritize hybrid interconnections. First, solar typically does not...

A new policy database aims to help cities, counties and townships be proactive when it comes to land-use issues. Thousands of megawatts of utility-scale solar power are expected in Michigan over the next decade, but most municipalities don’t have regulations to govern the land-use impacts. State officials and university researchers last week released what they’re...

With an average of 300 days of sun per year, the present and future of clean energies in Spain are focused undoubtedly on solar energy. By installing over 4GW of capacity in 2019 (14 times more than in 2018), Spain will lead the solar market in Europe this year, a landmark that illustrates the solar...
