The grid plan of Miletus in the Classical periodīy 2600 BC, Mohenjo-daro and Harappa, major cities of the Indus Valley civilization, were built with blocks divided by a grid of straight streets, running north–south and east–west. 2.2 Ecological features, rain water absorption, and pollutant generation.1.5 Early United States (17th-19th centuries).1.3 Europe and its colonies (12th-17th centuries).If there were ever a time for states to take notice – and support a cost-effective regional planning approach – that time is now. But some of these projects require at least a decade-long permitting and construction process, which means that the right decisions must be made right now if states want to meet renewable goals by 2035. In short, a lot is riding on transmission planning in MISO between now and next fall. MISO’s Board of Directors will vote on the initial conclusions from the Long-Range Transmission Planning Initiative toward the end of next year. What MISO launched this week is only the beginning of the road. Based on MISO information The time to act is now MISO has identified at least three areas with significant congestion that need relief, and its new initiative and other transmission plans can help to eliminate that congestion and allow cheaper - and cleaner - power to flow across the MISO region and subregions. Our grid is increasingly congested, which means that there is not enough space on power lines to move electricity from one area to another, which prevents MISO from delivering the lowest cost power to customers. MISO’s Planning Initiative also can help to address weaknesses in the existing power grid. It’s also an appealing plan for states, which enjoy the good jobs created by in-state generation, as well as lower electric rates enabled by geographically diverse generation. MISO’s approach not only reduces costs but also enhances the geographic diversity of generators, which is good for grid resiliency and will maximize the use of clean energy resources. ![]() This will mean a combination of longer interstate transmission lines and shorter in-state lines. Like with its last long-range planning process more than a decade ago, MISO announced that its new transmission planning approach will look at a mix of local and regional generation resources for states – an affordable path since some of the most efficient and low-cost renewable facilities may be located across state lines. In the roadmap laid out by MISO this week, we see the right elements for success. MISO was created in part to allow states and utilities to benefit together from infrastructure upgrades – and to avoid costly redundancy. This is where MISO and this week’s Planning Initiative launch come in. Unfortunately, without a change in direction, we’re going to be building more small, congested roads than larger highways. Imagine what travel would be like without interstate highways. The first option of leaving each utility and state to its own devices is inefficient and more expensive, puts frontline communities near fossil plants in harm’s way, and could even leave us with less reliable power. The problem is this: states and utilities aiming to move toward carbon-free energy either have to generate that power near where it’s needed, or else take advantage of a modern power grid that enables the delivery of lower-cost renewable energy from across a large region. Here’s what’s at stake: a much faster and more affordable carbon-free energy future with more jobs and less pollution. ![]() This process should deliver the right results – but only with support from MISO stakeholders along the way. It’s a challenge that got the start of an answer this week with the Midcontinent Independent System Operator (MISO)’s launch of its Long-Range Transmission Planning Initiative. With more utilities and states aiming for ambitious clean energy goals – and with developers eager to build low-cost renewables throughout the region – come stories of thousands of megawatts of clean energy projects falling out of the development pipeline due to transmission system constraints. ![]() The mid-continent’s electric grid is facing serious challenges.
